Dear Madam/Sir,
We have a digged a borewell ; where the water stuck at 700 ft, Hard Rock was found @ 80Ft. Borewell People Mentioned that water is around 1" and suggested to install 1.5 Air compressor pump.
But when we approached some pump dealers they suggested submersible pumps, so we installed 5 BHP Sumberesible Pumps; Now the pumps pulls water for 10 Minutes after that the water suddenly stops.

Now we are in a very much worried and we don't know what should be the next action that we should take.
