Dear Experts,

I have a borewell in my house at KR Puram, Bangalore. The depth is about 580 feet. Rock was hit at around 107ft and the casing is done upto 110 feet. The submersible pump is fixed at 440ft which is of 4 h.p. I have encountered some loose gaps and boulders @ 320 and 420 ft respectively, and I have inserted slotted pipes for the entire well to get rid of the possible issues with loose gap and boulders. I have used the borewell for my house construction without any problem for almost an year. Now from the past few days, water from borewell is muddy.

Please let me the possible reasons for getting muddy water & suggestion to fix it?

Regards

Naveen
