Why North's ponds matter for its groundwater
89%Semi-critical
North pumps out 89% of the groundwater that can safely be taken out each year (2025, Central Ground Water Board), which the board rates semi-critical. Every pond that holds rain long enough for it to soak in puts some of that water back, so the 148 ponds and tanks not in use are a recharge opportunity going to waste.
Bringing a pond in North back
Most ponds that are not in use can be revived. The work is the same in a village or a city sector:
Desilt
Dig out the silt that has sealed the bed, so water soaks into the ground again instead of evaporating.
Reconnect
Clear and line the channels that bring rain in, with a silt trap before the pond; divert sewage away from it.
Recharge
Add recharge shafts or wells in the bed where the soil is tight, so water reaches the aquifer faster.
Protect
Fence or plant the banks, mark the boundary and hand upkeep to the panchayat or residents' body.
