Rain Water Harvesting

Product/Process

Design system for storage of rainwater at domestic/community level.


Application/Use

Useful in areas where water supply schemes are expensive (e.g. hills), ground water is saline (e.g. coastal areas, islands); to supplement existing provisions.


Salient Features of Process/Technology

For a domestic scheme, rainwater run off is gathered from the rooftops, courtyards and small catchment platforms and stored hygienically in FC tanks after passing through filters. In community level schemes, larger catchment areas are used for collecting run off water in underground tanks, fenced reservoirs or directing the water to lakes.


Status of Commercialisation

Widely implemented in NE region.


Minimum Economic Unit Size

As per requirements of consumer.


Indicative investment

Rs. 2 lakh for 2000 L cap tank.


Equipment and Machinery

Masonry tools, smith tools, casting moulds.


Raw Materials

Treated roof/platforms, inflow system, by pass system, ferrocement water tanks of 200-2000 L cap.
