Repeated silting of borewell in Kengeri, Bangalore, Karnataka: Need permanent solution

I got a bore well drilled 2 months back at Kengeri in Bangalore, the depth of the bore well is 320 Feet. I also got a submersible pump of  1.5 HP installed at the depth of 270 Feet. Pipe diameter is  1 1/4 inch.

 The problem started when the pump got stuck and was unable to pump water. The pump was removed and cleaned for stones. The person who installed the pump came and serviced the bore well and informed me that silt has collected and he has removed and re- installed the mesh for it.

Now the problem has reoccurred, please advise as how to go forward.
