Why Tinsukia's ponds matter for its groundwater

9.5%Safe

Tinsukia pumps out 9.5% of the groundwater that can safely be taken out each year (2025, Central Ground Water Board), which the board rates safe. Working ponds are a large part of what keeps it there, by letting rain soak back into the ground.

Bringing a pond in Tinsukia back

Most ponds that are not in use can be revived. The work is the same in a village or a city sector:

Step 1

Survey

Map the pond's full original area, its inlets and its catchment, and record encroachments and sewage outfalls.

Step 2

Desilt

Dig out the silt that has sealed the bed, so water soaks into the ground again instead of evaporating.

Step 3

Reconnect

Clear and line the channels that bring rain in, with a silt trap before the pond; divert sewage away from it.

Step 4

Recharge

Add recharge shafts or wells in the bed where the soil is tight, so water reaches the aquifer faster.

Step 5

Protect

Fence or plant the banks, mark the boundary and hand upkeep to the panchayat or residents' body.
