I have a 380 feet borewell in my farm in Southern Tamil Nadu. This borewell currently has a yield of 3000 to 3600 litres per hour. The borewell was drilled in 2012 and a pump was installed a year ago in Feb 2016. The water from the borewell is a bit muddy but more of a pale white muddy mix (I have not tested the water and I do intend to test it) over the last 1 year.
