QUESTION
Borewell 820 feet,getting muddy water and sand, pump is blocked - Need suggestions to address the problem

Dear Sir,
We got 1.5" stuck around 330-380 ft depth. Until that point and as well after 450 ft only wet material was coming out during drilling and we dug upto 820 ft and we got 2" water we stopped at 850 ft. Until last month before the rains it was working fine(8 months), we did not face any problems with pump. We have inserted a pump upto 800 ft and now we are getting the muddy water plus white sand in the water (sand percentage is very low than previously it was cominng) but now we are facing the pump problem and as per the mechanic because of the mud and sand the fan of the pump is blocked. We are not able to run the pump more than a hour already. We have reinstalled the pump after the repairing it. Could you please suggest me the proper solution for this so that we can pump water properly without any issues with the pump. Waiting for your positive feedback.

Regards,
Sunil
