"EVERY DROP OF WATER FALLEN ON THE EARTH HAS A VALUE"
The irrigation department of Sri Lanka has defined a minor tank as a reservoir whose irrigable area is less than 80 ha. It is estimated that there are about 25000 minor tanks in Sri Lanka, most of them in dry zone. Out of these about 10000 tanks are functioning. The rest are abandoned. Over the past two decades several government and non governmental organizations have made attempts to rehabilitate the tanks that are abandoned.
