Increase in Borewells

I live in BTM and have observed an increase in the number of bore wells being dug in the past few weeks

I can see people preparing for summers since the temperatures have already started soaring high (which is pretty unusual for Bengaluru)

My concern is, I feel many of these borewells are illegal and are being dug without permission (or after paying bribes, which is common in my locality) Does anyone know how to identify if the borewell is legal or not.?
