About Rain Water Harvesting Programe

ABOUT RAIN WATER HARVESTING PROGRAME

OBJECTIVE: Match the legal compliance also to ensure the sustainable ground water supplies. Ensure cost effective, easy to operate and reduce the O & M Cost.

PROPOSED RAIN WATER HARVESTING STRATEGY: Roof top rain water is diverted to recharging through injection tube wells. Along excess rain water is treated with filtration system and use for other applications.

with this,

RWH SYSTEM DESIGN CONCEPT: Rain falls in Chennai -1200mm. Runoff coefficient -0.9 Collection efficiency -60%

Benefits of Rain Water Harvesting. Rain Water be harvested to conserve and augment the storage of ground water, to reduce water table depletion to improve the quality of ground water, and to arrest sea water intrusion in coastal areas. • • • • • •

naturally pure naturally soft (no dissolved minerals) free for those who collect it sustainable free of chlorine and its byproducts free of pesticides and other man-made contaminants
