A falling water table
CGWB has rated Lucknow city over-exploited in every assessment from 2017 to 2023, and pre-monsoon water levels deepened by roughly 1.4 to 13 m between 2014 and 2023, with the deepest reading of about 45.6 m at Aliganj. Tubewells that once needed boring to 80 to 100 feet now go down 220 to 240 feet, according to figures cited before the tribunal.
How we fix it
An APCON motor driver protects your submersible against dry running as the water level drops, along with overload, voltage faults and single phasing, and level control stops it once the tank is full.
