Water from borewell comes with mud
(not verified) posted 5 months 2 weeks ago

We have a submersible motor for apartment housing for seven families in Chennai. The depth of the bore is more than 100ft. Most of the time the water is turbid. Water should be available at a depth of around 60 ft. 

Any suggestions on what could be the cause for this? And what we can do to find out the issue?

Motor and pump stuck in borewell
(not verified) posted 7 months 3 weeks ago

Hi,

Have a motor and pump stuck in a borewell and we tried fishing it out. It's caught on something and almost overturned a tractor that tried to pull it. Someone who is coming to repair it said they wanted to go in with a wire and lifebuoy soap to pull it out - I was wondering if you can help me figure out if this will work? Or if there are other mud chemicals you recommend?
