PUBLISHER’S MESSAGE Trenchless Technology Award Trenchless Technology has become well known over the years for our Person of the Year and the Project of the Year awards. It’s always special for us to go through this selection process and then present the winners in Trenchless Technology. So it was with special pride that recently we were on the receiving end of a very nice honor. The American Society for Business Publication Editors presented Trenchless Technology a Gold Award for graphics excellence. The award was titled “Opening Page/SpreadComputer Generated”for the cover story that appeared in our April 2008 issue. The story was titled “The Numbers Game: Are Low Bids Undercutting the HDD Market?”This was a very appropriate cover story that even now about 18 months later, the topic is extremely critical considering the economic pressures. Named specifically in the award was our managing editor Sharon M. Bueno, and our graphic designer Sarah Hayes, who is also an accomplished artist.To view her work, go to www.sarahhayesart. com. We function on a publication team basis, and Sharon and Sarah are vital members of the Trenchless Technology Team.

Even More Economic News Every day we are bombarded with the state of the recession and opinions of when we will be emerging from it. Unfortunately, the construction aspect of the economy is in a lot worse shape than anything else. Per NUCA’s Aug. 12 “Washington Report,” the Bureau of Labor Statistics reported that in the latest month (July) “76,000 construction jobs were lost (marking the 25th consecutive month with significant job loss in the construction industry),” and that “1.68 million construction workers are out of work.” It is reported that the construction industry employment rate remains at 18 percent. NUCA goes on to report that the “water infrastructure (SRF) projects funded with ARRA (American Recovery and Reinvestment Act) money has until Feb. 17, 2010, to be under contract.” But it is generally understood that the bulk of these water projects are yet to be identified. But we know otherwise regarding the trenchless market sector. We do know that the smaller HDD work is hurting, as well as new construction trenchless work. But the water rehabilitation area has been strong. Perhaps, a good barometer is the recent reported results of Insituform, which said that its“North American Sewer Rehabilitation contract backlog reached a record level and increased 28.9 percent for the first quarter of 2009.” Furthermore, company officials say their “financial performance in North America Sewer Rehabilitation was the strongest [they] have seen in several years.”And referencing ARRA, they report “[they] also anticipate bidding opportunities to increase in this market as the impact of the stimulus dollars flow into the system.” The feeling is that the leadership in North America has finally gotten the message that we have to fix our water/wastewater systems. There are too many sinkholes, e coli bacteria in water off our beaches, drought and even drugs ending up in our water systems. The general population seems much more willing to accept rate increases, which in turn is a major funding source for water work. Some people say “the economy can’t get any worse,” but let’s all continue to push and work hard to have trenchless technology to lead in getting out of these horrible economic times. Best regards,

NEWS Tracking the Sewer Rat: Where Is He? During the last week of June, Mortimer the Rat traveled with Akkerman engineers Terry Fisher and Tim Fay, to Bogota, Columbia, to visit the headquarters of Ocesia.The company is currently finishing up in Fontibon installing local lines in this highly populated neighborhood for the Empresa de Acueducto y Alcantarillado de Bogota. When completed, this project will have installed 18 km of pipe. There were a total of six Akkerman pipejacking and guided boring systems owned by three different companies working concurrently on this project. Mortimer, Fisher and Fay visited a portion of this job where Ocesia used its Akkerman 4812 and 309 guided boring machine systems. Featured in the photo are Felipe Correa (holding Mortimer) and crew members from Ocesia, accompanied by Jose Escobar of Virtual Engineering (far right). Mortimer underwent a whirlwind travel experience departing and returning in three quick days. He enjoyed the open-air flea markets in Bogota where he dined on authentic ajiaco (potato soup), cocido (chickpea stew), arepa (unleavened corn bread) and perused racks of traditional clothing. He discovered a fondness for new recording artist Pipe Bueno and purchased his album. He endured some questioning from the staff at the immigration and customs counters in Minneapolis and Bogota airports but continued with no delay. You never know where Mortimer might show up next! Please check back for a complete accounting of Mortimer’s travels and also in an upcoming edition of Trenchless Technology or www.trenchlessonline.com.

Customers of Michels traveled to Wisconsin to take a “swing” at helping to celebrate the company’s 50 years in the construction business. The two-day celebration began on June 22 at South Hills Golf Course in Fond du Lac, Wis., for a shotgun start to 18 holes of golf. Golfers consisted of company president Pat Michels and many of the company’s vice presidents, along with customers and local dignitaries. They split up into foursomes and, despite the scorching temperatures, all had a great time. Locally based Holiday Automotive donated a new Chevy Malibu for anyone who could get a hole in one at the 10th hole — a 205-yard drive. Besides Mike Shannon, who donated the car, Dan Schwartz from Michels Pipeline came within feet of driving home in that beautiful car. After a day on the course, golfers were invited to a cocktail hour followed by a wonderful dinner at the golf course’s clubhouse. Raffle prizes were given away and Pat Michels spoke to the guests, thanking them for years of doing business with Michels Corp. www.trenchlessonline.com

The next day, Michels hosted an open house so customers could visit their new offices. Trenchless Technology publisher Bernie Krzys also attended the open house. Office and yard tours were given and employees and guests were all invited to a great buffet in Dale’s Diner.

CORRECTION The headline that accompanied the article on pgs. 24-25 in Trenchless Technology’s Lateral Rehabilitation Guide was misleading in that it identified American Water Resources, Inc.’s LineSaver® Program as an insurance program. While American Water Resources’ programs are offered as insurance in California and Virginia, the programs are offered as service contracts in all other states where American Water Resources conducts business.

GM Halts Production of Medium-Duty Trucks It’s been a long, hard road for General Motors (GM). GM filed for Chapter 11 bankruptcy in early June and has now announced that it will be winding down its medium-duty trucks. Production of the Chevy Kodiak and GMC Topkick medium duty trucks was to cease by July 31, 2009. For the past four years, GM has been attempting to locate a buyer for its medium duty truck business. Although it had several interested parties, GM was not be able to come up with a viable arrangement that would be in the best interests of both companies. Unfortunately, that has lead GM to get out of the medium-duty truck business. “We will be honoring all warranties on our medium-duty truck products and, of course, will maintain an adequate supply of spare parts for the foreseeable future,” said Jim Hopson, manager of Pontiac Communications. “We are currently working out all of the details regarding servicing the vehicles after the end of 2010, but customer’s first point of contact should still be their dealer.” Few details were provided by GM, as the company prepares liquidates the medium-duty assets over the next 18 months.

CWC Report Stresses the Importance of Infrastructure Investment A recent report by the Clean Water Council (CWC) steps up to illuminate facts that our elected officials need to know, in a time when Congress is considering a massive economic stimulus package. They need to know what we already do — investment in clean water infrastructure can create significant economic benefits right away. Titled “Sudden Impact: Assessment of Short-Term Economic Impacts of Water and Wastewater Projects in the United States,” the report shows that a $1 billion-investment in water and wastewater infrastructure results in total national output (i.e., demand for products and services in all industries) of between $2.87 and $3.46 billion, creates up to 26,669 new jobs (with average annual earnings for the construction portion of the jobs at an impressive $50,396) and generates personal (household) income of between $1.01 and $1.06 billion. In addition, each $1 billion invested generates approximately $82.4 million in state and local tax revenue. The report also shows that the targeted water and wastewater investment programs contained in pending economic stimulus legislation could, in short order, generate more than 300,000 skilled positions paying living wages. The results are based on actual data collected from 116 water and wastewater construction projects in five demographically diverse states, including 73 different counties. The projects were completed in 2006 and 2007, and encompass a comprehensive array of geographic regions, project types, size, materials, construction methods and labor markets. The output, jobs and income (direct, indirect and induced) tied to these projects were determined at the county, state and national levels using two respected input-output models and multipliers (IMPLAN and RIMS II).

INDUSTRY WATCH Design-Build Market Thriving for Water/Wastewater

A

report released by the Water Design-Build Council, a not-for-profit organization representing the leading design-builders of municipal water and wastewater systems, highlights the growth of the design-build method of project delivery for the nation’s water and wastewater infrastructure projects. The report, a four-year analysis of the Water Design-Build Council’s member firms, found that the sales value for the market grew nearly 80 percent in 2008 to reach $2.2 billion, representing 89 new projects. Geographically, projects in Florida, Arizona, Nevada and New Mexico represented 73 percent of all sales in 2008. “Increasingly, municipalities are working with design-build firms to address the need to repair, improve and expand their water and wastewater treatment facilities,” said Peter W. Tunnicliffe, president of the Water Design-Build Council and a senior vice president with CDM. “The growth of designbuild project delivery in the municipal sector follows the significant use of design-build delivery in the federal sector. The Council made recommendations to the Obama Administration and Congress that given the stimulus bill’s

priority to create jobs, the design-build approach allows states and municipalities to begin to complete their much needed water and wastewater projects more quickly than the traditional design-bid-build method.” From 2005 to 2008, Water Design-Build Council members reported design-build revenue of $6.4 billion and a total of nearly 349 projects across the United States. On average, 82 percent of member projects were design-build, while 15 percent were construction management at risk and 3 percent were design-build-operate.

Other Key Findings from the Report Include: • The average design-build contract duration from 2005 to 2008 was 1.8 years; • The median value of new projects was $3.3 million; • Projects inArizona,California,Florida andTexas accounted for 65 percent of the design-build market sales since 2005; and • The number of water and wastewater projects was nearly equal, at 47 percent and 42 percent, respectively.

FMI Weighs In on Stimulus’ Impact on Utility Construction Griff Morris, managing director of utilities business development with FMI, recently discussed the economic stimulus and its impact on utility construction at the CMAA Leadership Forum in Scottsdale, Ariz. Morris noted there is $16.8 billion available for utility construction through the Department of Energy, $3.2 billion of which has been allocated to state energy programs. Given this current situation in which regulatory commissions will be seeking help from constituents to compete for the stimulus funds, Morris predicts the following: • Stimulus funding will be delayed as new regulations are developed and implemented • Delays will take place during the next six to nine months and will be followed by a robust upturn in utility construction spending for traditional projects coupled with a serious upswing in new technologies spending and • Opportunities abound for utilities and major constructors, as well as residential and commercial builders to form new strategic alliances to take advantage of the changing landscape.

States,” the report shows that a $1 billion-investment in water and wastewater infrastructure results in total national output of between $2.87 and $3.46 billion while creating up to 26,669 new jobs. “The CWC took inventory of actual projects in order to fuel the models with real-world data that accurately reflect current activity. The report is short and sharp, and the economic findings are rock solid,” added Bill Hillman, CEO of the National Utility Contractors Association (NUCA), a CWC member.

Specific opportunities exist for: Utilities: • Assist regulators in understanding new rules and designing new regulations to help state public utility commissions compete for federal funds • Be positioned to shape regulations to improve their business Large EPC firms and Contractors: • Robust near-term business outlook, especially for those who can embrace advanced technologies and forge alliances with utilities to become a “builder of choice” for solar and wind generation facilities Residential/Commercial Builders: • Much to be gained in aligning with utilities to partner in conservation initiatives like weatherization, smallerscale solar power and home energy audits and efficiency improvements

NASTT to Celebrate 20-Year History at No-Dig 2010 Chicago has been chosen as the destination location for the 2010 No-Dig Show, May 2-7. 2010 is a very special year for NASTT, as it will be celebrating its 20th anniversary. In 1990, five key people began to brainstorm on the possibility of establishing a new association just for trenchless technology. That organization became known as NASTT and those five people became its founding members. Twenty years later, NASTT is a vibrant, growing organization of more than 1,200 members in the United States, Canada and Mexico. It is very appropriate that we return to the birthplace where NASTT began — in Chicago — to celebrate this significant milestone. To showcase the 20-year history of NASTT, the society has planned a multi-media exhibit including interviews of past chairs, photographs and video, among other special events and awards.

American Augers Sta West Salem, Ohio, Company Remains a Key Player in the Auger Boring & HDD Markets By Sharon M. Bueno

A

merican Augers’ auger boring roots trace back to 1963 with the construction of one auger boring machine that was built in a small garage in a rural Ohio community. Today, the company is a worldwide leader in auger boring and maxi-size horizontal directional drilling (HDD) equipment with international product dealers representing all corners of the globe. With a milestone anniversary just a few months away, American Augers has grown exponentially from its modest garage beginnings, as has its reputation and position in the trenchless marketplace.

ays True to Its Roots Al Richmond may have started this manufacturing venture by building one auger boring machine, but in 2009, American Augers is a multi-million dollar manufacturing company with eight different auger boring machine models and six different maxi-size horizontal directional drilling rigs leading its product fleet. American Augers also produces HDD mud systems, auger sections and cutting heads and in recent years has added vertical drilling rigs for the oil and gas market, tapping into that growing market. The American Augers campus — once comprised of just Richmond’s garage — now spans 240,000 sq ft (including a recent 100,000-sq ft addition) and has grown from a handful of employees in its inception to 150 today, making the company one of the largest employers in the West Salem, Ohio, area. “I never had the opportunity to meet Mr. Richmond but I’m sure he would be amazed if he walked through here today to see the products we build, the quality of our engineering department and the worldwide support,” says American Augers president James Pfeiffer. “I’m sure he had a vision for where auger boring could go but I’m sure he never had a vision for how far it has come.” While today’s technology has made equipment faster, bigger and more powerful, not much has changed since Al Richmond built that first auger boring machine when it comes to quality, customer service and ingenuity — they are ingrained in the American Augers’ philosophy.

The Early Days

American Augers vice president of marketing and sales Dan Sharpe (left) with company president James Pfeiffer.

As its name suggests, American Augers made its reputation on its auger boring machines. But before it was known as American Augers, it was first Richmond Mfg. and it was run by Al Richmond right out of his garage in rural West Salem and for a time, he was the company’s only employee. In a bit of auger boring symmetry, the American Augers manufacturing site today is the former Richmond Mfg. facility, albeit a little larger in building size and product scope. “Al [Richmond] was approached about building auger machines by two gentlemen for the oil and gas industry,” Pfeiffer says. “He did such a good job that they decided they wanted more and he started building them in his garage. It grew from there. He acquired the property next to his house and he built the building that is now our warehouse. Our warehouse is actually his true manufacturing facility.” American Augers was spun off in 1970 by four Richmond Mfg. employees in Wooster, Ohio, to produce auger boring machines and the company later expanded to include equipment for pipe jacking, tunneling equipment and directional drills. In 1989, Augers Unlimited purchased Richmond Mfg. American Augers purchased Augers Unlimited in 1995, relocating the company back to its original home in West Salem. “We really came full circle as a company,” Pfeiffer says. In 1999,AmericanAugers was purchased by Chattanooga,

Tenn.-based Astec Industries, a manufacturer of continuous and batch process hot mix asphalt plants and asphalt recycling equipment, as well as a holder of companies that produce rock crushing machinery, road paving equipment and other soil remediation products. Once acquired, American Augers became part of Astec’s underground division. Over the years, as American Augers continued to grow, it expanded its walls at its West Salem facility, with the first coming in 1996 when 30,000 sq ft of factory space was added to the existing building, as well as a state-of-the-art paint booth. A second expansion began in 1999 to increase office, manufacturing and storage capabilities. The most recent addition just finished up this summer, after a 100,000sq ft building was constructed to meet the needs of its vertical drilling manufacturing operations.

Trenchless Markets With “auger” right in the company name, it’s no surprise that auger boring remains at the core of the company product base. “We were the first to focus on auger boring from the beginning,” Pfeiffer says. “American Augers is well identified with the auger boring growth of the trenchless market — from our name to our branding position. We are known for our auger boring machines. It is still a core part of our business to this day. Our name is synonymous with auger boring machines.” Today, eight models of auger boring machines are available from 24 to 96 in. in diameter, where in the early days, 12-in. 24

machines were the norm. While those are still made, American Augers has evolved with the changing market.“We have seen the work become more involved with larger diameter projects and we’ve been able to develop larger diameter machines with more horsepower to meet the needs of our customers,” Pfeiffer says. Auger boring will always be a key product — it’s what the company was founded on — but the HDD market has grown to be its largest asset and perhaps most critical to the continued success and survival of American Augers. Its first HDD rig was produced in 1988 and in 1991, American Augers became the first HDD rig maker to eliminate chain drives on the rigs and instead use a rack-and-pinion carriage design, which is now an industry standard. In 2002, its maxi-size rig line was introduced. With the overwhelming growth of the HDD market over the last 20 years, this facet of the company offers a higher dollar benefit to its bottom line. Six different maxi rigs are manufactured (all in excess of 100,000 lbs of pullback with some reaching beyond 1 million lbs of pullback). Today with a push toward large pipeline projects for natural gas, maxi rigs, such as those produced by American Augers, are tied to that market. But the growth of the oil and gas market drew the company into another aspect of it: vertical drilling. In 2006, a customer approached American Augers about taking one of its HDD rigs and modifying it for use as an oil and gas rig.That first rig was a slanted one, not a true vertical rig but its success gave company officials the impetus to dive into the vertical drilling market in 2007. The current model — called the VR500 — was released in 2008. Pfeiffer came to American Augers in 2005, taking the helm of a company that held a high standing in the auger boring market.And he arrived with a name of his own known to the trenchless market, having spent some 18 years with the Charles Machine Works/Ditch Witch. “This is truly a very small niche industry. [The trenchless marketplace] isn’t like Coca-Cola where you have millions of customers. We have a few hundred,” Pfeiffer notes. “Many customers who I knew years ago, I know today.” And with that experience, Pfeiffer has lived through the HDD industry’s ups and downs, viewing the market as cyclical. Companies need to prepare for the down times to ride them out. “We go through a rollercoaster ride like a lot of companies,” he says.“We had great growth in the 1990s and early 2000s. With the downturn of the fiber-optic business, that had a real impact on our industry. Now we are going through one of those swells again where the [HDD] market has slowed.” One aspect of American Augers that has proven to be an integral part of its success is its international base, which represents 45 to 50 percent of its business and is at a point that Pfeiffer is comfortable with. While it does some international auger boring work, it’s the HDD side of things that makes up its overseas sales. In 2008,American Augers exported drills to 19 different countries, including China, Australia, Brazil, Saudi Arabia, India and Turkey, to name a few. “One of the keys internationally is that you have to have distributors or agents in the countries you are working in,” Pfeiffer says. “In North America, we sell direct to the customer and that’s one of our strengths — direct contact with the customers. Internationally, with the culture and language differences, we have found it easier to have a dealer or strong agent to help with sales.” www.trenchlessonline.com

Key Issues American Augers is not unlike many of the U.S.-based manufacturing companies that have taken a punch to the gut with the downturn of the economy. Like its competitors, American Augers has been forced to downsize its workforce in the last year as the manufacturing sector slowed. “The economy has had a huge impact on the trenchless market,” Pfeiffer says. “If you look at the sheer numbers from the Association of Equipment Manufacturers’ [AEM] reports, the number of unit shipments is down drastically.The economy is having a huge impact on all of our businesses. People are so nervous about what is going on in the economy that they are just not willing to make the investment in new equipment, more so than any other time that I’ve been professionally involved… These are unchartered, extremely difficult times.” While the economy remains the manufacturing industry’s No. 1 concern, there are other challenges facing companies like American Augers. Pfeiffer sees the new EPA emission regulations — called Tier standards — for off-highway diesel engines, particularly those with more than 175 hp, as having an effect on manufacturers. For the construction industry, off-highway diesel engine Tiers are coming to a head. The final and most stringent set of regulations (Tier 4) are already here. The Tier 4 standards for all horsepower ranges are fast approaching in 2011 through 2015. “The Tier 4 engines will create many challenges for manufacturers,” Pfeiffer says, noting the problem today is that — in his view — the “engine manufacturers are not as far along as we hoped they would be.”

Another challenge Pfeiffer sees is the ability for companies to keep up with the ever-changing technology but not going overboard with it. “There’s a challenge within all of our organizations to keep up technically and continue to add more sophistication in machines and at the same time keeping them simple enough and basic enough that the average user can work and maintain them,” he says. “This industry is really starting to face the challenge of ‘Are we getting more sophisticated than we need to be?’” With all the turmoil in today’s market, Pfeiffer does see American Augers coming out of this period stronger and better equipped to handle whatever comes its way. “We’re still optimistic about our products and the market. We’ve got a lot of support from our parent company and we’ve made a big investment [with the new addition],” Pfeiffer says. “We still believe there’s an opportunity for a lot of growth in the vertical, HDD and auger boring markets. We recognize that this is a down market but we know that there’s a lot of water and sewer infrastructure that needs replaced. I personally believe natural gas will be the clean fuel of the future for the next 50 years and a lot of natural gas pipelines are going through. We’re still optimistic that we’ll come through this period stronger than when we went into it and better prepared to grow and support our customers.” Sharon M. Bueno is managing editor of Trenchless Technology.

Sliplining in France Pipe Selection Helps Rehabilitate Highway Culverts

T

he French highway network spans almost 12,000 route km, 60 percent of which are administered in a concession system by private companies such as APRR (Autoroutes Paris-Rhin-Rhône). Thousands of metal culverts have been installed along the roads to channel water and more than 50 percent of these are steel circulars or arches. After being in service for 30 to 40 years, these culverts have reached their maximum lifetime and are at risk to collapse any time, causing road ruptures as far back as 20 years ago: Road embankment, paving and culverts needed to be repaired immediately, which required an expensive construction of temporary diversions for both water and traffic. 26

As a consequence, the highway companies conducted an extensive inventory. First surveys provided a better overview: A significant number of the steel constructions (corrugated galvanized iron culverts) and a number of concrete culverts showed serious defects. Consequently, all six highway companies introduced a compulsory rehabilitation program, in accordance with the technical specifications by the French Water Act of 1992. On this account, HOBAS GRP Pipe Systems have contributed to the security upgrade of the construction and highways. Thanks to its environment-friendly characteristics and its exceptionally long-lifetime properties, HOBAS GRP is a material that fulfills all requirements. It should www.trenchlessonline.com

also be noted that the HOBAS solutions for this project are based on trenchless technologies, which permit work without traffic disruptions. The project was located on Highway A31, which connects the town Beaune and Luxembourg and is part of the APRR network. APRR is a subsidiary of the Eiffage Group, the seventh largest building and concession company in Europe, and is in charge of the second-most important French highway network with 1,800 km. This project is noteworthy for its dual purpose: • To rehabilitate damaged metal pipes that were severely corroded for some parts, • To extend the road by one lane in each direction. Moreover, rehabilitation involves a group of 11 largescale hydraulic constructions, nine of which were originally elliptical, one was circular but strongly buckled and one was in the shape of an arch. The total length of installed pipe adds up to 685 m. APRR first invited tenders that HOBAS France approached. An overall solution was developed considering the geometry of each channel and grouping the constructions by size. This led to the proposal of four different and individual NC-Line profiles, plus one circular CC-GRP Pipe OD 1720 for the rehabilitation of nine elliptical constructions. Standard CC-GRP HOBAS pipes were suggested for the remaining circular constructions and for the arch a NC-Line ID 2880x1800. Apart from this, an alternative solution was proposed sliplining NC-Line arches and HOBAS CC-GRP pipes using both

HDPE & Pre-Chlorinated Pipe Bursting Helps to Rehab Michigan Water Pipes By Steve Cooper

T

he City of Livonia, Mich., found the way to save its water system and also keep costs under control by selecting pipe that is long-lasting, leak-free and makes it possible for a highly desirable method of installation to be used. Just a 30-minute drive from Detroit and with a population of almost 100,000, the City provides more than 16 million gals of water daily (mgd) to more than 38,000 residential, commercial and industrial customers through some 400 miles of water main pipe that varies in size from 3 to 36 in. Like many other communities today, it was faced with potentially expensive decisions concerning sections of the water system nearing the end of its useful life. Much of the system grid is well beyond its original 40-year expectation, with some pipes older than 60 years. For many years, the iron pipes were cracking and coming apart at the joints. System failures due to water main breaks were a growing problem.The ductile iron pipe, from large trunk lines to smaller distribution branches, was also prone to constricted flow due to tuberculation that was caused by the buildup of rust and sedimentary deposits of various salts, such as iron and magnesium precipitates. The regulating authority for water in Michigan is the Michigan Department of Environmental Quality (MDEQ). Current guidelines indicate that if a municipal water supply is to provide service to customers and for fire protection, the minimum pipe size is 6 in., while maintaining a residual minimum pressure of 20 psi at all points in the system. Not only was the City of Livonia facing the inability to maintain Pipe bursting with HDPE pipe was used to rehab some of the City of Livonia, Mich.’s aging pipes. 30

pressure and flow, there was also the loss of treated water due to the leaks, plus the possibility and risk of contamination due to infiltration of groundwater and other outside materials. “During the past 20 years, we experienced an increasing number of incident reports of broken water mains that required digging up the streets to do the repairs,” stated Livonia Mayor Jack Kirksey.“At first it was manageable. But during the past five years, the failing sections were reaching a catastrophic stage. Not only were we losing water — a valuable resource — but the cost to our taxpayers was significant.We had to find a way that would solve this problem and also be financially prudent. In other words, find the best system that would last the longest and have the most realistic cost.” City of Livonia water managers worked with local consulting engineering firm Hubbell, Roth and Clark Inc., Pontiac, Mich., to pinpoint the best way to save the water system. They also turned to the Plastics Pipe Institute

(PPI), an educational trade association representing all segments of the plastic piping industry, for information, recommendations and guidance to remedy the problem. An analysis of the system found that nearly 23,000 ft of deteriorated water main was in need of replacement. The aging pipes were generally 6 to 8 in. in diameter and it was obvious that replacement was warranted to maintain the integrity of the system. The consulting engineering firm assembled contract documents that were publicly advertised for potential construction contractors to bid. The documents allowed replacing the pipe with a similar iron product or with pipe made from high-density polyethylene (HDPE). “Both HDPE and iron pipe are industry standards for water main supply and are acceptable to the City of Livonia,” explained Daniel W. Mitchell, P.E., of Hubbell, Roth and Clark. “Although Livonia specifies the use of polywrapped, cement-lined, ductile iron, (called DI), pipe for water main use, HDPE pipe has also been allowed in recent years. The reason for this is that

the HDPE pipe enables the trenchless method of installation to be used.” Typically, water main replacement involves excavating equipment to dig up roads and residential lawns. The pipe is then laid out, sections joined together, connections made and the trench backfilled.This method is expensive because of the labor required and also puts residents on the defensive because of the disruption, safety concerns and traffic detours. The City’s water managers recommended using HDPE pipe because it provided the single solution to the multifaceted problem of doing the repair. PPImember company Charter Plastics, Titusville, Pa., HDPE pipe was selected for the replacement and upgrade. Various methods of construction were considered. A relatively new technology known as “pre-chlorinated pipe bursting” that utilizes HDPE was identified as the most cost-effective through the bidding process. The method of installation made possible by the use of HDPE pipe involves using the old pipe as a pathway and bursting it as the new HDPE pipe is pulled through the failing ductile iron pipe. Only small entrance

and exit pits are needed to accomplish the replacement and upgrade, not the extensive trench digging normally required. Charter Plastics’ PE 3408 Ductile Iron Pipe Size HDPE pipe was used. Its solid wall design and physical characteristics allows pipelines to be relined by using trenchless pipe bursting technology. It meets AWWA requirements for polyethylene pressure pipe and also meets ASTM F714 requirements. The HDPE pipe was joined by heat fusing the sections together in the field using a McElroy 412 self-contained fusion machine. This method was faster and more efficient to do than welding or clamping iron pipe and it created a single, monolithic pipeline, free of potential leaks even though it was blocks long in some areas. McElroy Mfg., Tulsa, Okla., is also a PPI member company. “We were putting in a total of more than 27,000 ft, which means a savings of more than $200,000 just for the pipe, not including cost associated with the labor and time that would be needed to handle and install the much heavier iron pipe. The end-result is that we were able to do this without raising the rate for water,” Kirksey said. Once the process began, it went very quickly. Most homes were reconnected to the system within three to four hours. The project started in April 2008 and finished that October. Hubbell, Roth & Clark’s Dan Mitchell summarized the initial steps. “The City knew it had a problem, and [Major Kirksey] along with the City Council and others established a budget they felt they could afford to address the problem.The staff was asked to prioritize the worst areas for a capital improvement program that would be within the budget. Once a scope of the project had been identified, the City solicited for engineering services in order to design, prepare bid documents and administer the construction of approximately 27,000 ft of new main — 23,000 ft as replacement main and 4,000 ft of new main for looping purposes.” After making the decision to replace the failing water system, the City’s concern turned to the destruction of both public and private property usually required when an underground system — water, gas, sewer and conduit — is installed. The City didn’t want residents to face a hardship from ripped up streets and sidewalks. Because HDPE pipe is somewhat flexible, strong and durable, it provides the ability to horizontally directional drill the pipe in close spaces — just a small hole about 3 ft wide to start each run. From that starting point, the crew was able to snake the pipe through the old ductile iron pipe. This www.trenchlessonline.com

reduced the cost and eliminated the need to open-cut. Plus the pipe has fusion-welded joints for zero leakage, it’s corrosion-resistant for a long life and it meets AWWA standards for potable water applications. If the traditional open-trench method was used to install the new pipeline, it would have been necessary to set up road barriers or detours, making navigating the streets difficult and dangerous while further upsetting drivers and pedestrians. According to the PPI executive director Tony Radoszewski, “The popularity of using polyethylene (PE) pipe in municipal water systems has continued to grow. Officials on the state, town, city, county and federal levels find it to be an economical and environmentally-sound solution with proven longevity and reliability to replace aging pipe systems.” “What Mayor Kirksey and his team did for Livonia is no different than any other leader can do,” Radoszewski observed. “By investigating alternative technologies, a major problem was solved, plus the community and construction workers were protected from unnecessary turmoil and dangers.

“Too often we hear or read about a construction project that was the site of a disaster after a backhoe hits a gas pipeline while digging a trench. Or a trench caves in, burying workers. From 2000 through 2006, there were 271 deaths related to trench work, according to the latest United States Bureau of Labor Statistics. “Mayors, city managers, public works directors and consulting engineers realize that digging trenches that upend and endanger lives is unnecessary now,” he stated. “The technology and products now exist that permit a more safe, practical and economical way to install a water system. “We are facing serious challenges when it comes to crumbling underground infrastructure — namely water and sewer pipes — and billions of dollars have been specified for water and sewer infrastructure projects,” he continued. “Decisions about materials used and how repairs or expansions are done are vital to us all.The choices about to be made will have an impact on us now and for generations to come.” On Feb. 20, a large contingent of mayors met with President Obama, mem-

bers of his Cabinet and Vice President Biden to discuss cities’ role in implementing the American Recovery and Reinvestment Act (ARRA) and how to get billions of dollars allocated by the stimulus plan flowing to cities. “Pipe systems made from high-density polyethylene do not rust and are leakfree — the two biggest problems facing water utilities today. Our city’s gas utilities almost exclusively use HDPE pipe for these very reasons,” Radoszewski said. “Furthermore, HDPE pipe systems are ‘green’ in every sense of the word. They are sustainable, use less energy to manufacture and ship, many times they are less expensive than traditional materials like concrete and metal and with superior joints, they are better at protecting natural resources.“ Kirksey had some advice for other mayors:“The use of HDPE pipe is a progressive step that all other cities should consider to reduce costs and disruption of daily life during the project and to improve their water infrastructure with a long-life product.” Steve Cooper is a freelance writer who frequently reports on the water industry.

TTC Retrospective Trenchless Technology Center – 20 Years of Groundbreaking Research & Counting

T

he year is 1989, you have just returned from your lunch break during which you caught up on news reports on the latest developments in Eastern Europe (was the Berlin Wall really going to be opened?).You return to your desk and, while glancing over the curled faxes awaiting you (isn’t this new technology great!?), you see a slick-haired stranger approaching, briefcase in hand. Your sewer department had been faced with a host of issues — backups, overflows, broken pipes, sinkholes — and this salesman says he has the answer to your problems (so this resin-saturated felt can seal my pipes while not digging up the streets?). It seems almost too good to be true. You need more information. But where can you find it? It was in this environment in which theTrenchlessTechnology Center (TTC) was founded at Louisiana Tech University in Ruston, La. At the time, technologies like directional drilling, microtunneling and cured-in-place pipe were making inroads, but little was known about these methods. That’s where TTC came in. And while TTC served as a clearinghouse of informa34

tion for utilities, it also served as a seedbed for new product development and a medium by which industry and academia could share knowledge. Today, the Trenchless Technology Center carries on this tradition and remains one of the premier research centers focused on underground utilities worldwide. As TTC begins its third decade, it will do so under new leadership. Upon the retirement of its director, Dr. Ray Sterling, the reins have passed to Dr. Rob McKim, who will serve as administrative director, and Dr. Erez Allouche, who will serve as research director. Both men have long histories in the trenchless technology industry, as well as with TTC. Allouche is an associate professor of civil engineering at Louisiana Tech and has been with TTC since 2003. McKim returns to Ruston following stints in industry and academia. McKim worked at TTC for three years from 1998-2001. As the trenchless market has matured since the founding of the Trenchless Technology Center (which was originally called the Trenchless Excavation Center), the role of the center has evolved to keep pace.“The pioneers of trenchless technology www.trenchlessonline.com

brought a vision, ingenuity and tremendous talents in the fields of mechanical and hydraulic systems, and TTC’s role was to spread the gospel and assist in the acceptance and incorporation of these technologies into the marketplace,” Allouche said. “As the market has grown, TTC’s role has shifted to assist in the development of new technologies, materials and concepts that will assist companies and utilities in improving the services they provide in terms of enhanced quality, lower costs and reduced impacts.”

Sowing the Seeds One of the hallmarks of the Trenchless Technology Center has been a collaborative environment between industry and academia — an environment that still exists today.That collaborative spirit is not surprising considering the Center’s founder, Dr.Tom Iseley. Iseley grew up in the pipe laying business and worked as a contractor before pursuing higher education and a teaching career. While completing his doctoral studies in the field of trenchless technology, Iseley recognized a void in research. “We really lacked in some areas of trenchless technologies, particularly in microtunneling and rehabilitation techniques,” said Iseley.“I (From left) TTC’s Erez Allouche, research director, Ray Sterling, former director, and Rob McKim, administrative director, at the No-Dig Show in Toronto. felt what the industry needed was a mechanism to help facilitate R&D.” One project in the early days made a profound impact on the emerging field of trenchless — the Construction Productivity Advancement Research (CPAR) program — conducted jointly by TTC and the U.S. Army Corps of Engineers’ Waterways Experiment Station in Vicksburg, Miss. CPAR was one of the largest trenchless research projects ever conducted and included fullscale field research experiments on seven pipeline rehabilitation systems from five manufacturers; three microtunneling systems under controlled ground conditions with extensive instrumentation and monitoring; and small directional drilling systems.The findings of the research led to the development of the “The Guidelines for Trenchless Technology: CIPP and FFP Rehabilitation Systems, Mini-HDD, and Microtunneling.” “The CPAR studies were very important in establishing some engineering information to go along with the use of directional drilling, microtunneling and liner design in North America,” said Sterling, who took over as director in 1995. When TTC was established, it did so with an Industry Advisory Board (IAB), which provided guidance and financial support. In some cases,TTC provided the ideal research For more information visit www.trenchlessonline.com/info

and development medium for these growing companies.“At that time, some of the smaller companies that were involved in the industry didn’t have the wherewithal to perform the research themselves, so TTC filled that role,” Sterling added. The research and students who have been associated with TTC have had lasting impacts on the trenchless marketplace. Many Tech grads have entered the market as consulting engineers and con-

tractors, or entered academia to introduce trenchless to the next generation of engineers.Additionally,TTC served as the model for the Centre for the Advancement ofTrenchlessTechnologies at the University of Waterloo in Canada, founded by McKim.

one wonder whether they have anything to do with trenchless — ultra-wideband radar, geopolymers, nuclear magnetic resonance. “The mix of research that has evolved since Erez Allouche has joined the center has shown the capabilities and the desirability of having a center like this,” Sterling said. “We are doing advanced research in a number of areas that are not strictly trenchless, but they are being applied to the installation, inspection and rehabilitation of utilities.” Allouche concurred.“We have had more of a focus on fundamental scientific work and the development of new technologies,” he said. “We have also expanded the traditional soil-structure interaction and linear research areas to include software development, development of electromagnetic and acoustic sensor technologies and material sciences including polyurea, polyurethane and geopolymer.” Many of these areas of research are in line with the projected needs of the industry, which include improved inspection and assessment technologies and asset management. “The location and characterization of buried utilities is going to remain an important area that is nowhere near developed yet,” Sterling said.“We need more than just a visual look at the pipe. We need to figure out what the material properties are and where the voids are outside the pipe. By getting this type of information we can better predict how long a certain type of pipe or rehabilitation can be expected to last.” McKim envisions TTC continuing to play a role beyond research. “New technologies have been slow to catch on in North America, but by researching and testing new products before they are introduced in the field you can reduce the risk,” he said.“In the past,TTC has done testing and pilot projects and refined products before they entered the market, and that helped to facilitate their success and growth. In my mind that’s one of TTC’s key accomplishments” Additionally, TTC’s dialogue with industry has been important in disseminating information, as well as keeping a finger on the pulse of needs of the market. One way that TTC maintains the dialogue is through the Municipal Forum series, which consists of regional meetings that bring together city leaders and industry for a day of discussion on all relevant topics. With the increased acceptance of trenchless technologies and the needs associated with building and repairing underground infrastructure, the Trenchless Technology Center will no doubt play a major role for the next 20 years and beyond.

Resin Selection for Cured-In-Place-Pipe Applications By Bill Carroll

T

he cured-in-place-pipe (CIPP) industry has experienced phenomenal growth since its inception nearly 40 years ago. It has become the method of choice for rehabilitation of deteriorated underground sewers and pipelines due to its low installation cost, ease and speed of installation and minimization of ancillary requirements such as traffic rerouting, security, etc. One of the facilitators for this fast growth rate and ready market acceptance of the technique is the use of unsaturated polyester (UP) and vinylester (VE) resins. These workhorses of the thermoset composite industry have a long track record in corrosion-resistance applications. With an extensive database developed over decades of service, UP and VE resins and composites were well suited for adoption by the CIPP industry. In addition, the physical characteristics of these resins are quite amenable to the CIPP process. Low viscosities allow them to easily flow through and wet out the felt and fiberglass tubing used to reline existing pipeline systems. The resins’ ability to cure quickly and under a variety of conditions made for easy implementation. Their ability to cure thermally, through initiation by organic peroxides, as well as by exposure to ultraviolet light widened the opportunities to design systems to fit a great diversity of field applications. The heart of the CIPP system is the resin matrix. It causes a limp, flexible felt tube to become a rigid, structural member, allowing the free flow of liquids 38

and effluents through it. Its main function, though, is to provide resistance to the wide variety of chemicals often encountered in municipal sewer systems. From the moderately benign soapy water, waste products and cleaning solutions from personal residences to the harsh chemicals discharged from industrial manufacturing plants, the resin itself must not degrade over the design lifetime of the CIPP system. In addition, it must display sufficient integrity to maintain longterm structural effectiveness. In choosing a resin for a CIPP system, it is first necessary to identify the types and concentrations of the chemicals to which it is expected to be exposed. Thermal resistance is not usually an issue in underground applications but must be taken into consideration if installed near facilities that discharge liquids at above-ambient temperatures, such as discharges from pulp and paper mills. A secondary consideration is the potential for chemicals to come in contact with each other in the CIPP system. Often, municipalities have a history of material within an existing environment or they have performed analyses of their current eff luents to identify types and concentrations processed within their system. The workhorse of UP corrosion-resistance applications are isophthalic resins. The term “isophthalic” resins cover a broad range of resin types and applications in the composites industry. Corrosion-resistant resins, however, are a fairly narrow slice of polymer compositions. While it www.trenchlessonline.com

is the crosslinking through the carboncarbon double bonds of UP resins that turns them into a 3-D, thermoset matrix, a very high crosslink density results in a brittle matrix with limited structural properties and toughness. Substitution of isophthalic acid for part of the maleic anhydride in the polymer reduces its crosslink density with little loss of resin modulus and allows an effective balance between rigidity and toughness. The aromatic character of isophthalic acid is highly resistant to a wide range of chemicals, as well as providing good temperature resistance. The co-reactants with the acids that result in a polyester polymer are glycols or diols. These also affect the chemical resistance of a CIPP resin. Branched diols are preferred as the side groups on these molecules, which inhibit small molecule ingress into the main polymer chain and help prevent chemical attack. Ether glycols, such as diethylene glycol, are usually avoided as they exhibit somewhat of an open structure and the oxygen of the ether group can readily attract polar molecules such as water. Corrosion-resistant isophthalic resins are usually high in molecular weight. Chain scission of the polymer backbone degrades the material and its corrosion-resistance properties, so starting with a high molecular weight means it can sustain more attacks on the backbone before it loses structural integrity. Swelling of the polymer also results in a loss of structural properties.Again, a higher molecular weight results in fewer end groups to attract attacking chemicals and also contributes to less free volume in the matrix and less ability for molecules to penetrate the network. A higher reactivity resin, meaning a higher crosslink density, also inhibits the transport of molecules through the matrix and results in a higher degree of chemical resistance. High molecular weight equates to high viscosities so CIPP resins are usually high in styrene content to lower their viscosity into the range needed for fast and efficient tube wet out of multi-layer felt tubes. Isophthalic type resins offer a moderate degree of chemical

resistance. They can readily meet the resistance requirements of ASTM F-1216 for CIPP applications. Isophthalic resins are resistant to acids, salts, dilute chemicals and offer some degree of solvent resistance so they are suitable for use in most domestic and residential piping systems. They are not recommended for alkaline and oxidizing environments and are not resistant to aromatic and chlorinated solvents. Vinylester resins provide the next step up in chemical resistance. These resins, typically based on Bisphenol-A epoxides, contain a highly aromatic backbone, making them more resistant to chemical attack and provide greater resistance to temperature vs. isophthalics. They also contain fewer ester groups than isophthalics so they are more resistant to hydrolytic attack and have somewhat better resistance to bleaches, alkalis and solvents. While isophthalics can handle

most domestic eff luents, when industrial chemicals are involved in the environment they often are more aggressive both chemically and thermally. This is where VE resins should be considered. They offer a 20 C to 50 C (68 F to 122 F)

higher use temperature than isophthalic resins and are resistant to a wider range of chemicals. However, they are also not resistant or aromatic and halogenated solvents. When specifying resins for an industrial type environment, the materials the CIPP could potentially be exposed to should be reviewed thoroughly. Resins can often handle small quantities of chemicals that they normally would not resist in concentrated or long-term exposures. Also to be considered is when varied chemicals are present, there are interactions and reactions that can occur between materials that could compromise CIPP life. The highest degree of chemical resistance in a commodity resin type is found with Bisphenol fumarate resins. As with VE resins, these contain Bisphenol-A in their backbone but these resins have a higher crosslink density so they are more resistant to some chemicals than VE and offer resistance at higher temperatures. Bisphenol fumarates find high utility in oxidizing and caustic environments. In corrosion applications, they have been used for many years in chlorine dioxide and sodium hypochlorite containments. Again, these resins are not highly resistant to aromatic and chlorinated solvents. While the previously cited resins are used in the majority of CIPP applications, certain specialty resins occasionally find utility in specific environments. Terephthalic resins generally perform on par with

isophthalics. Epoxy resins are used but their chemical resistance can vary widely, depending on the curing agents used. They often do not develop optimum properties without a post cure. Epoxy novolac vinylesters can provide better chemical and thermal resistance than Bis-A based vinylesters as they achieve a higher crosslink density. Urethane-modified vinylesters can be more resistant to some media than standard VE resins. Filled resins are becoming more popular as they can provide a more cost-effective CIPP solution but the chemical resistance of the filler must also be taken into account in any application. While many are fairly inert, materials such as calcium carbonate are readily decomposed by acids and are not a good choice in a CIPP resin system. The CIPP industry has capitalized on the extensive history of unsaturated polyester and vinylester resins in corrosion environments to establish itself as the premier method for pipe and sewer rehabilitation. As with any corrosion application, the expected CIPP environment should be well understood before choosing the resin system. With their broad range of capabilities, unsaturated polyester and vinylester resins are well situated to participate in the continued growth rate of the CIPP industry.

Tight quarters at the back of the DreamWorks campus

A “Dream” Job Vitrified Clay Pipe Selected to Install Sewer Line Under Movie Studio By Mike Van Dine

T

ight timelines, a spaghetti mesh of existing utilities in the area, a cooling tower, electrical power vaults, buildings on the very edge of the easement that left no room for equipment or staging, parallel construction of an adjacent four-story story building and fiber optics that fed one of the most highly recruited and high profile companies in the country — DreamWorks. This job had it all. As a part of ongoing sewer system upgrades, the City of Glendale, Calif., planned to abandon the existing sewer line in the DreamWorks studio campus in favor of a new, larger, relocated line, approximately 40 ft to the west. In this congested urban campus, the options for routing the new line weren’t good, but after two years of negotiating the new easement, there was no going back.

Improvement project called for both open-cut and trenchless installations (both pilot tube and jack-andbore methods), with a final depth of 20 ft, but one section of the project created some exceptional demands. The plan called for the new line to follow the contour of the Los Angeles River (LA River) between the river and the DreamWorks Studios. The timeline had no room for delays because a new DreamWorks Studio Animation Building was slated to be built as soon as possible after the old line was abandoned (the new building was intended to be placed on top of the old sewer line). Construction of the animation building and the sewer line were to run concurrently. The addition of the building construction eliminated over half the available working space and further restricted access to the site.

This photo shows the drill bit coming out of the receiving pit.

The tight timelines, lack of room for equipment and concerns about existing utilities all pointed to using pilot tube microtunneling (PTMT). This method provides a very accurate (within ¼-in. up to 300 lf) installation with very little surface disruption. Because of the sensitive nature of some of the DreamWorks equipment and the exacting nature of their work, even excessive sub-surface vibration would have created unacceptable productivity loss. Jasmina Zigic, P.E., project manager for the City of Glendale, said,“We considered other materials, but the people at the National Clay Pipe Institute provided all of the information and documentation we needed to evaluate and specify clay pipe for both the open-cut and the trenchless parts of the installation.” “Some people still aren’t aware that clay pipe can be used in this kind of installation,” according to Joe Parker, vice president of technical services for the National Clay Pipe Institute (NCPI). “But we were able to work with the city to demonstrate the efficacy of VCP in this setting.”

Both the installation method and the ability to eliminate the external casing pipe were advantages for vitrified clay pipe (VCP). Because of its high-compressive strength (18,000 psi on average), leak-free joints and affordability, VCP is the predominant pipe material used in PTMT. The soil borings showed fill soils, 2 to 18 ft. The fill soils consisted of silty sand and were uniformly well compacted. The underlying natural soils consist of stiff to very stiff silt medium dense silty sand and medium dense to very dense poorly graded sand and well graded sand. “This job was another reminder that you should always be prepared for the unexpected,” said Parker.“In the midst of the job, we unexpectedly came across a boulder at a location that could not be potholed for retrieval.The boulder damaged the powered cutter head (PCH), causing a leak in the hydraulic fluid line. Luckily, this occurred at the last trenchless installation. To complete the installation, the contractor switched to biodegradable oil to be able to continue boring without contaminating the groundwater.” The jacking and receiving shafts were just 8 ft in diameter. During the installation process, spoil was displaced by the slant-faced steering head.The pilot tube was directed on line and on grade by rotation during advancement. The operator’s skill was critical in identifying unexpected or out of place utilities. DreamWorks became an important part of the team in identifying the active utilities and helping to keep the project on schedule.

In PTMT installations, the hollow stem of the pilot tube creates the optical path for the camera to view the LED target in the steering head displaying the head position and steering orientation. The pilot tube line establishes the centerline for the new sewer. The bore is then increased by the installation of a reaming head followed by augers in casings, which transport the spoil to the jacking shaft for removal. The final step to increase the bore used a PCH, advanced by the product pipe, which transports the spoils into the receiving shaft. “The challenges on this site made this an exceptional installation,” according to Zigic, “but it all worked quite well. We won’t have any hesitation about using this method and VCP again.” “The team effort on this job was impressive,” according to Parker. “At every step of the way, the City of Glendale, their contractors and sub-contractors and DreamWorks staff all seemed to understand that the nature of this job demanded a first-rate team. And they all came through.” Mike Van Dine is president of the National Clay Pipe Institute, a non-profit technical resource for design, installation and operation of vitrified clay pipe (VCP) gravity sewer systems. Established in 1944, NCPI is the authoritative resource for civil engineers and contractors designing, specifying and installing VCP sanitary sewer systems.

DIRECTIONAL DRILLING

Ground Conditions Wetlands Offer Challenging River Crossing By Greg Ehm

Earth Energy piggybacked the reamers for hole stability.

T

he soil conditions in Idaho create challenges that can leave the most experienced horizontal directional drilling (HDD) contractors scratching their heads in disbelief. That was the case for Earth Energy when it was faced with the task of installing a 24-in. HDPE water line under the Boise River in downtown Boise, Idaho. Soil conditions in this part of the state can range from cobble to sand to rock formations all within a 500-ft bore. So it takes a great deal of planning, patience and experience to complete underground installations in this part of the country, and that’s where Earth Energy comes in. Earth Energy was formed in 1989 by Erv and Darrin Hoge.They began by placing drops for the phone company, which included plowing, trenching, splicing and a variety of underground operations. In 1993, the company expanded into larger utility installation projects and today the company specializes in providing HDD services for the installation of fiber optics, phone, power, gas and water and sewer lines. Earth Energy also provides HDD services to the petroleum and gas industries, along with remediation of hazardous waste sites. 56

River Project with Multiple Challenges Earth Energy was contracted by United Water, the local potable water utility in the Boise area, to install a new 24-in. HDPE water main across the Boise River.The water main was being installed to provide a more reliable water source and line pressure to existing and new customers in the rural part of northeast Boise. “Earth Energy has a long-term relationship with United Water and their prime contractors to provide directional drilling services on new large-diameter water mains and the smaller service lines to commercial and residential customers,” says Erv Hoge. Prior to providing a bid for the project, Earth Energy conducted a series of site visits to determine the general layout of the area and met with the local utility companies to determine the location of existing underground facilities that may be within the proposed bore path. One of the primary utilities was an existing gravity sewer main crossing the river near the vicinity of the proposed bore. Another critical issue was the location of the utility easement along existing residential homes, which limited the amount of room between the sewer line and private www.trenchlessonline.com

property. Once these boundaries were determined, Earth Energy could proceed in developing a running line and profile for the new water main. The 640-ft bore would pass under the Boise River and a parallel stream, designated as a sensitive trout fishery, as well as a wetland area. Earth Energy was asked to maintain a minimum depth of 15 ft below the bottom of the stream and minimum setbacks were required away from the stream and river banks to prevent encroachment or damage to the wetlands and the sensitive flood plain area. “Overall the terrain across the bore path is relatively flat except for a drop in elevation of approximately 6 ft within the stream banks and river,” says Hoge. “The entire area within a quarter mile of the bore was also within the floodplain of the river.” Some of the challenges in completing this bore included maintaining the proper alignment within a limited utility corridor across the stream and river. In addition, the ground conditions varied between a loose gravel and cobble material to sand lenses and back to cemented cobble. The bore began on the creek side with a setback of 150 ft to get to the desired depth of 27 ft below the river bottom and ended up on the river side 100 ft from the bank. Earth Energy used its Vermeer D100x120 Navigator horizontal directional drill for this project — the newest addition to its fleet of six Vermeer drill rigs.The unit produces

100,000 lbs of pullback force and was fitted with a 6.5-in. single-roller type cone drill head for the pilot bore. “The pilot was pretty difficult,” says Burke Williams, operations manager for Earth Energy. “Due to the cobble, it was a struggle just to keep our pitches within reason for the diameter pipe we were installing. Once we got into the more solid formation, the bore went smoothly until we exited and again we had trouble keeping our pitch in the loose material.” To make matters worse, the pilot bore had to be completed with an arc to avoid pilings from a future bridge that was to be installed parallel to the bore path. Once the pilot bore was completed, Earth Energy utilized a series of roller cone-rock reamers to pre-ream the borehole to a 36-in. diameter before installing the 24-in. HDPE pipe. “We piggybacked the reamers,” says Hoge. “Once we completed a backream, we would use that same reamer to lead a larger-diameter reamer through the borehole. The piggyback procedure provided us with some stability inside the borehole considering the ground conditions.” With each 6-in. increase in borehole size, additional challenges were created in maintaining the proper mud mixture to remove the drill cuttings and prevent the borehole from collapsing. Earth Energy constantly adjusted the bentonite mud mixture to maintain the borehole. The loose unconsolidated cobble material near the surface was

the most difficult to maintain. The 24-in. HDPE waterline was staged on the exit side of the bore and United Pipe of Boise, Idaho, used a fusion machine to fuse the 50-ft segments. Earth Energy used a 32-in. cobble reamer to pull the 640 ft of pipe into place. “The pullback was a piece of cake,” says Williams.“During the pullback, our pressure never exceeded 60,000 psi, considering we were pulling more than 53,000 lbs of pipe into place.The total project from pre-planning to completion took 42 working days.”

Planning Tools Invaluable One of the advantages of using Vermeer equipment is the availability of Vermeer Bore Pilot and Atlas Bore Planner software to design the directional bore. According to Hoge, the initial step in utilizing the bore software was to determine which directional drill would be used on the bore. Once the drill size is determined, a topographic surface is built with the software and the desired depths along the proposed route are input into the software program. “The software designs the bore profile based on the allowable bend radius of the drill stem being used,” says Williams. “The computer will warn the user if the desired depths along the bore change too quickly for the drill stem in use.” Once the bore was completed, the actual as-built depths were input into the software and a comparison showing design vs. the actual was graphically shown. This project was one of Earth Energy’s more difficult due to the size of the pipe, the sensitive nature of the waterways and the variable conditions of the material to be bored.“We knew with proper planning and the right equipment we could complete the job and there really weren’t any surprises along the way,” say Hoge.

ELECTRONIC DRILLMASTER

Locate — The Need to Expose & Monitor By John Archambeault

nderground utilities and the HDD industry have mixed liked oil and water since the industry’s inception. Accusations and complaints — both real and imagined — have been hurled back and forth between the utility industry and the drilling contractors. All parties realize that the way to prevent damages is to expose the utilities in the drill path or adjacent to it before drilling. How do you do this in a way that is cost-effective and minimizes destruction to roads, improved lawns and grounds?

U

price of a high-end utility locator is quite low compared to two to three crewmembers digging for two hours a day, five days a week and 52 weeks out of the year. It is also a good idea to take note of the surrounding area of the bore path. Is there a gas grill in the backyard? Is electric or gas heat in the garage or a shed in the backyard? Can you see a trench line where there are no utilities marked? Most utility companies are not required to locate these lines on private property.

Utility Locators

Non-destructive Means

How do these 40-plus-ft deep bores get located? Most utility locators only locate to depths of 20 ft or so. All states in the United States now have a call-before-you-dig law. Basically, this law gives the utility company two to three days to locate and mark its utility.

Once the utility has been located, there are three methods that can be used to accomplish its exposure: mechanical exposure and pneumatic- and hydro-excavation. Mechanical exposure can be accomplished by either hand-digging or through other mechanized means such as a backhoe. Hand-digging requires a tremendous amount of time in order to dig a pothole to the required depth of the buried service. Another consideration, other than time and manpower, is the possibility of injury to workers using the shovel method. Using a backhoe for exposure increases the amount of restoration required to return the area to its natural condition and further increases the possibility of damage to the underground utility. Pneumatic- and hydro-excavation practices are by far the best methods to use when attempting non-destructive exposure of buried utilities. Pneumatic-excavation retrieves the spoil in a dry condition, which can later be used as backfill, while special hydro reduction digging tools make this a one-person operation. Both methods can dig a 6-in. diameter hole to a depth of 5 ft in less than 20 minutes. Furthermore, the vacuum excavator can perform doubleduty by vacuuming drilling fluid from the sump in front of the machine and removing frac-outs along the bore path. Finally, to bore either above or below a given utility without exposing that service and monitoring the progress of the drilling head and reamer is not recommended. It is senseless to put your crew and yourself in harm’s way to install a service. In our industry, we need to exhibit professionalism when working with buried plant by locating, exposing and monitoring the installation.

Once the utility has been located, there are three methods that can be used to accomplish its exposure: mechanical and pneumatic- and hydro-excavation.

Pipe and cable locators broadcast a radio signal on a utility and the receiver reads the signal. Some locators can simultaneously broadcast two or more signals, and the receiver will tell the person locating which signal is flowing better on the utility. Ninety-nine percent of the locating manufacturing companies agree the best way to locate a utility is to direct-connect to the line. Coil clamps are another option for broadcasting a signal to a utility line. Indirect or induction broadcasting is by far the most inaccurate method to locate. This method can broadcast a signal to all the utilities in the area and confuse the locate personnel. Some HDD locators on the market today will also locate underground utilities. Many HDD contractors double-check the utility marks in the bore path. Even though there is a red line painted on the ground signifying a buried electric line, the contractor still needs to expose this line by non-destructive means. How many times has a contractor hand dug to a depth of 5 ft with no electric line visible? Contractors need to perform their own locates by someone well versed in utility locating. This person is usually the HDD locator because of the vast experience this person has locating the HDD head.The 60

DIRECTIONAL DRILLING

PVC Pipe Successfully Installed in Iowa HDD Project By Sarah Humphreys

A

West Point, Iowa-sanitary force main project for a new subdivision called for 2,570 ft of 4-in. C900, as well as ability to work around less-than-perfect conditions. Heavy rains leading up to and including the project’s first day made for wet and muddy soils. For the underground-utility contractor, KM King Construction of Burlington,Iowa,this was a typical installation. KM King Construction,which has been performing horizontal directional drilling (HDD) for about seven years in response to a high volume of cast-iron-pipe-replacing reconstruction work in the area, is accustomed to a high water table and otherwise tricky situations. But company president Kim King was also ready to try something new. Specifications from project manager and engineer Jack Pope, Gardener & Associates, Oskaloosa, Iowa, called for a C900 product with external joint restraint in the form of couplings with O-rings.The product required the installer to align the pipe and couplings and then insert a nylon spline. KM King Construction requested a material substitution for a C900 product that included internal joint restraint instead. “I had used it several times and had good success with it,” says Pope of the external restraint product.“This was the first time I’d seen Eagle Loc 900. Based on the specs I was provided,

it appeared it would meet the requirements of the project.” Eagle Loc 900 is a C900 PVC pipe from JM Eagle whose bell is fitted with BullDog internal joint restraint manufactured by S&B Technologies. The BullDog system includes a Rieber gasket, iron grip ring and casing. When the installer pushes the spigot end of the pipe into the bell, the pieces lock together. Restraint is internal; there is no need for tools or external rods, clamps or bolts, which are susceptible to moisture and, consequently, corrosion. The internal restraint also eliminates the need for frequently used concrete thrust blocks. These can interfere with other infrastructure elements, make for a labor-intensive project, increase material costs, require too much space, stray from the engineer’s specs and make later excavations difficult or impossible. “We thought that it would be an easier installation and save time,” says King of the request for the substitution.“The other product required more time to fasten the joint.This seemed to be the perfect product for what we needed to do.” One of the things they needed to do was avoid disturbing adjacent sports fields, where soccer and baseball tournaments were going on.The specs called for HDD on about half of the project and left the rest of the installation to the contractor’s www.trenchlessonline.com

discretion. KM King Construction, whose projects are about 50 percent open-trench and 50 percent HDD, chose the latter installation for the entire job. “We didn’t have to directional bore but it was our choice to do that,” King says.“The city was in favor of it and it made for a happier relationship with the customer. We didn’t have to disrupt anyone. We could stay out of everybody’s way.” King’s team installed the pipe 5 ft deep in 400-ft sections, boring with a 4-in. bit, then pulling an 8-in. reamer attached directly to the pulling head and pipe. No service connections were installed on the pipeline.They chose not to pre-ream the hole due to the silty, sandy conditions with no visible rocks. King reported that the whole project went as smoothly as the pipe sliding into the ground. It reduced the labor needed because the crew assembled the pipe in one string before pulling it in, allowing them to complete other tasks on the project. This project had the length of a field on which it could link the pipe, however, in tight areas, Eagle Loc 900 pipe can also be snapped together one piece at a time close to the point of entry. “With the specified product, you have to make two connections at every joint, you have to place the locking spline at every joint, and there’s two of those at every joint,” he says, estimating that takes 15 minutes per joint, at a joint every 20 ft.“That’s quite a bit of time.With Eagle Loc 900, it’s like slipjoint pipe. You slip it together and it’s done.”

King says pulling the pipe through the ground is also easier without the previously specified product’s shoulder on the connectors. The new pipe reduced the restriction, he says, and installing the pipe was complete in six days, with the subcontractor completely off the job by seven days. Although this was KM King Construction’s first time using internal joint restraint in a project and Eagle Loc 900 was introduced in March 2009, the BullDog technology has been tried in the field since 2006. It is also used in direct-bury construction, restrained road bores and aerial crossings. The Eagle Loc 900 product is available in DR18 in diameters ranging from 4- to 12-in. PVC pipe for use in distribution, pipelines of potable water, municipal water systems, force main sewers and water reclamation projects. Having passed the Million Cycle Test per UNI-B-13, the system is designed to conform with industry standards — including AWWA C900, ASTM D1784 and UNI-B-13 — so there is no need to modify existing s pecifications. King says his company will use internal joint restraint for more projects, including those that require horizontal directional drilling. “We thought it would save us time,” he says.“And it did.” Sarah Humphreys is with JM Eagle, a Los Angeles-based pipe manufacturer.

Hydro-Powered Cutters Meet the Growing Demands

L

ateral reinstatement, one of the most time-consuming aspects of pipe relining, is typically performed by pneumatic cutters that are winched into place and monitored by an adjacent CCTV crawler. This arrangement worked fine for contractors when relining was a niche industry, but tightening regulations and crumbling infrastructure have commoditized relining services, so staying profitable means stripping inefficiencies from the process. Moreover, relining materials have grown more durable, requiring cutting power that exceeds what existing technology offers.

Solutions often come from regions of the world that have borne higher regulatory burdens for longer periods of time. In Western Europe, for instance, hydro-powered cutters have emerged to deliver increased productivity while slashing overhead requirements. Powered by high-pressure water, these cutters generate five times the torque of their pneumatic counterparts, allowing them not only to cut faster without stalling, but to mill out an entire connection rather than leave a coupon to cause problems downstream. They also cut at up to 30,000 rpm, leaving exceptionally clean edges that require no post-cut brushing.

By Mike Russin

Hydro-powered cutters commonly integrate onboard cameras, as pressurized water is readily available to rinse cutting debris from view and to actuate outriggers that minimize vibration. These onboard cameras eliminate the expense of an auxiliary CCTV crawler to monitor cutting progress. Many hydro-powered cutters are also self-propelled, saving the time and resources required to string a winch line from a secondary manhole. Self-propulsion not only allows these cutters to crawl up to 500 ft, it adds another axis of cutting motion to the cutting arm’s bend and rotation. Furthermore, hydro power can be packaged compactly, allowing cutting in lines as small as 2.5 in. Lateral reinstatement is harsh work, and maintenance — routine and unplanned — is part of any relining crew’s daily activity. In fact, many relining operations incur the expense of keeping an extra cutter system on hand just to avoid downtime. With a water-cooled motor that has few moving parts, hydro-powered cutters require substantially less maintenance and are easily serviced in the field. Water also cools the cutting bit, allowing it to perform up to 90 hours before it’s replaced. Hydropowered cutters typically use diamond-impregnated hardened steel cutters, which are better matched to the speed and torque of hydro-powered cutting, and last longer when cutting hard UV-cured liners and performing pre-lining tasks. In fact, protruding taps, raised joints, roots, grout flashing, rebar and other hard materials can all be cut on a single run. Mike Russin is advanced technologies manager for Envirosight.

Our Failing Water Infrastructure: We Can Rebuild It Smarter, Better & Greener

W

hen you’re faced with an impending disaster, isn’t it only natural to take steps to prevent the catastrophe? Believe it or not, our towns, cities and entire communities are on the cusp of such a situation. I’m talking about our nation’s water systems — they’re failing. Water main breaks are popping up regularly and news reports are increasing about flooding that puts citizens in harm’s way. Yet we continue doing things the same way and expecting different results — isn’t that the definition of insanity? It’s time to implement smarter, greener, more sustainable solutions. The major culprits are older degrading pipelines that get patched up using traditional materials. This predicament is worsened by a lack of regulation over water loss from leaking pipe systems. Yet, these are easy to correct. First, let’s take a look at the situation. The figures for water loss are staggering. Due to the limitations of traditional pipe systems, it is common practice for utilities to accept and anticipate 10 to 15 percent rate of water loss. Current industry standards allow leakage rates for newly installed potable and storm water systems. Public water systems serving more than 1 million people in the United States average a loss of 17 percent. New York City pegs its loss at 10 percent: Daily water use is just more than 1 billion gal. The world loses around 33 percent of its drinking water each year. It’s not only a ‘cost-of-water’ issue. Leaking sanitary sewer and storm sewer pipes can also pose environmental and health issues. These circumstances point to a dire need to regulate water loss and leaking pipes. If it became mandatory that infrastructure managers reduce water loss by a certain percentage each year and totally eliminate it in the next decade, for example, there would be significant benefits. Perhaps 70

most important would be the reduction of potable water waste. This would push back the timeframe when additional water resources — new wells, reservoirs, water supply contracts with neighboring states, etc. — would be needed and help to fight periodic droughts. The NewYork Times Op-Ed columnist, Bob Herbert recently questioned, “I wonder what it will take to get this country serious about repairing and rebuilding its crumbling and increasingly obsolete infrastructure.” He then referenced the 2009 “Report Card for America’s Infrastructure” produced by the American Society of Civil Engineers (ASCE): “America’s drinking water systems face an annual shortfall of at least $11 billion to replace aging facilities that are near the end of their useful life and to comply with existing and future federal water regulations. This does not account for growth in the demand for drinking water over the next 20 years. Leaking pipes lose an estimated seven billion gallons of clean drinking water a day.” Mr. Herbert concluded: “We’re suffering now from both a failure of will and of imagination.” This does not have to be the case. It can be changed. Plastic pipe provides favorable labor and material costs, ease of installation, superior joints and a lower carbon footprint when compared to traditional metal and concrete pipe. It’s lighter, easier and practical to transport, requiring less fuel for delivery. It can be installed in many cases through trenchless applications that minimize destruction of an area and the need to re-route traffic. Plastic doesn’t rust, won’t discolor water, is corrosion and abrasion resistant, doesn’t tuberculate and doesn’t lose its long-term hydraulic efficiency due to internal pipe wall build up. Best of all, because highdensity polyethylene (HDPE) pipe sections and fittings are fused together delivering a completely monolithic

pipe system, it’s totally leak free. There are glimmers of hope. On a city-by-city basis, solutions are being implemented. One example is in Cascade, Idaho, where the underfunded and neglected infrastructure water and wastewater systems were on their last legs. Upon realizing the benefits of HDPE pipe, a plan was implemented to replace the mishmash of concrete, steel, cast iron and just about every other type of pipe that had been previously used. For Cascade, the possibility of future water loss was eliminated. Another is Tulsa, Okla., where old metal pipes leak water at an alarming rate and water conservation is a priority. These conditions, coupled with the city’s awareness that HDPE pipe is used by the area’s oil and gas industry where zero-leakage is critical, convinced the city to install it for potable water systems in new sub-divisions. These types of revitalizations are growing. But, new rules are needed. Regulations could be developed insisting advanced materials such as HDPE pipe be considered as part of the due diligence for a new system or the repair of an existing one. If we are serious about helping to minimize our carbon footprint and protect precious natural resources we need to apply innovative greener solutions that deliver sustainable performance characteristics and thereby prevent all-too-familiar catastrophes.
