Product/Process
:Process
to augment under- ground water resource and check soil erosion.
Application/Use:Sustainable water supply in dug wells/hand pumps; augment
drinking water supply & irrigation potential, check soil
erosion, reclamation of wastelands.
Salient Features of Process/Technology
:
The concept of 'hill to valley' is adopted
to arrest rainwater at selected points in the catchment area.
In the hilly terrain, continuous as well as discontinuous
trenches are made while in the valley, continuous trenches,
boulder check dams or ponds are constructed on secondary/tertiary
drains. These water storage structures recharge the ground
water and raise the water table level. This also checks soil
erosion. Micro watersheds can be planned in semi-arid zones.
It takes 3 yr for marked impact.
