Water tables falling year on year
PHED data put the depth to groundwater in Patna Sadar at about 20.9 feet in May 2025 and 25.9 feet in May 2026, a drop of roughly five feet in a year, with Danapur and Maner falling too. Officials blame concrete cover that sends rain into drains instead of the ground, and PMC's own repair rounds include replacing burnt pump motors.
How we fix it
An APCON motor driver stops the borewell pump the moment it runs dry, guards against overload, voltage swings and single phasing, and fills the tank automatically so no pump runs longer than it needs to.
