Sir,

We have a borewell which has depth of 120ft. We lowered a submersible pump (ordinary) in it upto 100ft. A few days back we noticed that the water output is decreasing, so we called the mechanic who told us of the silt problem. We tried to lift the pump using various methods, but it was no use. So now I require your help with respect to same, please tell me as to how I can lift the pump and retain the borewell for further use.

Thanks
