It is the techniquemof collection, filtration and storage of rainwater at surface or in subsurface aquifers, before it is lost as surface run-off,such that the collected water can be harvested in the time of need.
Perlocation Pit
The perlocation pits are shallow structures that help the rainwater to permeate through soil strata.Along with prelocations trenches they play an important role in ground water recharging.
Retention Pond
Retention ponds are ponds designed with additional storage capacity to attenuate surface run off during rainfall events.
Aquifer Borewell
Aquifer Borewell method are the most efficient rain water recharging technique, which directly charges the aquifer and reduces the wastage of rainwater getting into sewage drain.
