Please consider three main aspects before recharging the storm water into the ground.
One the stormwater runoff must not be contaminated with Industrial pollutants, fertilisers, pesticides or sewage. It is important to evaluate the catchment area and the possible ingress of any unchecked runoffs in this catchment area.
Two, the infiltration area must also be unpolluted, if the land selected for ground water recharge already has seen infiltration of industrial pollutants in the past, the ground water recharge efforts will do more harm than any good.
Direct recharge into ground water via direct vertical shafts is a strict no. The RWH structures generally designed in India are only meant to be connected to clean roof tops.
Please consider use of Geocellular blocks under long grass bioswales for creating infiltration basins if you are sure of the quality of stormwater.
