Artificial Recharge of Groundwater

Product/Process

Process for recharge of ground water aquifers/hand pumps/dug wells tube wells through rainwater.

Application/Use

For providing sustainable drinking water to villages having acute water scarcity, particularly during summer months.

Salient Features of Process/Technology

The groundwater structures are recharged by allowing rainwater to percolate down the aquifers at leisure pace thereby raising the water table. For this activity, suitable weathered/fractured zones are identified for recharge after field investigations w.r.t. geology, topography and location. Micro catchment artificial recharge plan is developed. In a typical case of hard rock, small stop/check dams are constructed in pervious geological formations, which allow percolation of rainwater. The impact can be noted after 1 yr.
