I am from Bangalore. I have a borewell which is at 160 feet and the guy who dug the borewell said there are boulders at 45 feet. My local guy put the submersible pump at 60 feet and at 50 feet, but motor stops operating because of sand getting into the motor.

How do I pump water out with this sand problem and this water is mainly for agriculture. I grow paddy which requires more water.

Please help
