India is rich in water with an average rainfall 1150mm. This translates into water availability of 10000 liter per person per day. However, domestic water consumption is 100 lit per person per day. Do we have 10 times more water then we need? Obviously not. The food we eat requires a huge quantity of water to agriculture. In future demand for food, and water will grow because of population increase. How could we to tackle this?

This project involves method of construction of water harvesting structures, depending upon nature of soil, topography of land, intensity of rain, availability of materials to trap every drop of rain water where this drops transfers in to farm well by ground water recharging or pumping.
The M.S.Swaminathen Committee has estimated the cost of water shed development in Maharashtra to be around Rs.6000 per hectare.
The present irrigation system of large dams & open canals is outrageously expensive, costing between Rs.100000 & 300000 per hectare. Large dam lose 25-50% of water through evaporation & percolation so in case with canal. Also area required for construction of dam large which create problem of rehabilitation of people.
