corner of India, is a small hill state having an area of about 21,000 km2
and thinly populated. The state is entirely mountainous covered with green
vegetation. Villages are mostly located on hilltops. Mizoram State enjoys
abundant monsoon rainfall of about 2500 millimetres annually. But Run-off is
quick and people face acute water problems in the dry season. Villagers have to
walk long distances to fetch water from perennial springs and rivers. The
English who came to the area in 1894, got their domestic water from a 12- lakh
gallons capacity underground rainwater tank.

collection are the main sources of domestic water supply in Mizoram. With the

pumping scheme. Pipe water supply is supplemented by rainwater harvesting in
most of the towns and villages. Many families prefer rainwater for direct
consumption to pipe water.

of the important development schemes. During the International Water Decade
substantial funds for rainwater collection were released on a state as well as
