Borewell disintegration from bottom

Farm Questions

Hello sir,

My old borewell of 200ft had a submersive motor and running fine for 10yrs, suddenly closed. We tried hard to bring the motor out which was covered with mud/clay. Later we tried to clean it but the technician said beyond 10ft he couldn’t insert the pipe and it has closed completely.

We decided to put new borewell. Water started oozing out from 40ft. It was hard rock till 200ft and then white spongy rock( we could squeeze water from it). We decided to stop after 50ft. So entire borewell is 250ft (rock till 200ft and spongy till 250ft). Initially while drilling the soil was caving in so pvc pipes were inserted till 60ft. Then till 250ft we hv put sloter pipe. Initially we placed motor at 170ft, first run of day gave water for an hr. After One hr break, only for 8min. So we decided to Place motor at 200ft. Before placing it we measured the depth and it was only 236ft. Later, we made it run 10min every 1hr.

Coming to problem, after a month’s time the water was coming with white sedements and then motor went on dry run(shows 15amp). Plumber suspects that the spongy rock is disintegrating and could have reached the motor.

What are our options? We do not have any open space to put another borewell.

  1. should we clean the borewell and place submersive motor at 150-170ft? (But what if bottom disintegrating continue?)

  2. Can we change to compressor/jet motor, will this solve our problem? Please help!

Overhead tank is at 3rd floor.

May I please know your location? Also, have you contacted any professional consultant or borewell technician to properly diagnose the borewell before taking the initiative to install the PVC inner casing?

Borewell disintegration from the bottom can be a serious structural issue, often caused by soil instability, poor casing, or long-term erosion. It’s important to address it quickly, as it can affect water quality and overall well safety. A professional inspection can help identify the root cause and prevent further damage.
