Pumps that lose the water table
In the dry months of March to May, household pumps in parts of Guwahati fail because the water level drops beyond their reach, and deep borewells have been reported running dry in Six Mile, Jyotikuchi, Survey and Panjabari. CGWB has classified major parts of the city as semi-critical for groundwater extraction.
How we fix it
An APCON motor driver senses dry running and stops the pump before it burns, retries after a set interval and protects against voltage faults, while tank sensors make sure every litre the borewell gives goes into storage.
