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.
Status of Commercialisation:
