Water table depth in South
Most of the 12 wells the Central Ground Water Board measured in South read over 40 m. 83% were deeper than 20 m, beyond the reach of hand pumps and shallow borewells.

Is groundwater in South running out?
South pumps out 103% of the groundwater that can safely be taken out each year (2025, Central Ground Water Board). More is pumped out than rain puts back, so the water table keeps falling. Recharging rain from roofs and open ground is the way to lift the water table back up.
Frequently asked questions
What is the water table depth in South?
In CGWB's pre-monsoon 2018 readings, groundwater in South stood 5.8 m to 65 m below ground (19 to 213 ft) across 12 monitoring wells. Most of them read over 40 m.
How deep is a borewell in South?
A borewell has to reach well below the water level, and in summer the level drops further, so in South it has to go past 65 m (213 ft) where wells read deepest. The exact depth depends on where the water-bearing rock or sand layer is, which a local hydrogeologist or driller can tell from nearby bores.
Is the water table falling in South?
South pumps out 103% of the groundwater that can safely be taken out each year (2025), rated over-exploited. Pumping more than rain puts back means the water table keeps falling. That is 151 points lower than in 2017.
How deep should a rainwater recharge bore be in South?
About 200 ft is typical where most wells read over 40 m, deep enough to pass the clay layers that block water and reach sand or fractured rock that carries it down to the water table. The final depth is set on site from the soil seen while drilling.
