Is groundwater in Kolara running out?

184%Over-exploited

Kolara pumps out 184% 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 Kolara?

In CGWB's pre-monsoon 2018 readings, groundwater in Kolara stood 1.2 m to 13.3 m below ground (4 to 44 ft) across 31 monitoring wells. Most of them read 2–5 m.

How deep is a borewell in Kolara?

A borewell has to reach well below the water level, and in summer the level drops further, so in Kolara it has to go past 13.3 m (44 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 Kolara?

Kolara pumps out 184% 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 27 points lower than in 2017.

How deep should a rainwater recharge bore be in Kolara?

About 60 ft is typical where most wells read 2–5 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.
