I have drilled a borewell (1006 Feet) in 2015 December - I got water in two sources (2.5 inches) one at 550 Ft and the other at 750 Ft. Earlier I used to get water continuously even for 6-7 hours/day. But nowadays i am getting water continously only for 30 minutes, after that I'm not getting water. I need to wait for 1.5 hours to run the next cycle. I placed the pump at 850 feet, (4HP 40 Stage/ AQUQ TeXMO - Model RF10A/40) - so I am planning to lower the pump at 990 feet to at least get water continuously for 1 to 1.5 hours).

Pettugodalu is a small village in Hukumpeta, a tribal mandal of Visakhapatnam District with 150 members. The village has 30 acres of the land, 100% dependent on rainfall. There is a stream passing at 200 feet distance to the land and at a depth of 70 feet where from June to January, water flows at 3 feet height. The villagers are ready to give half of acre of land for storing the water. But, the issue is that all the villagers are wage seekers, and cannot invest from their pockets. The panchayat has come forward to invest 10,000 rupees to bring the water to these 30 acres.

I have a borewell dug till 300 feet. Suddenly last week, water stopped pumping out from the borewell. When I switched on the motor and when the ampere reading showed 15A, water was being pumped out. Now from last week when I switch on the motor the ampere reading is showing 20A volt meter is showing 220V constantly, and water is not being pumped out. I checked whether there is water in the borewell, by putting camera inside it, and saw there was sufficient water. What does this signify?

We recently had a 4.5 inch diameter boring in our house for domestic use. The technician dug the borewell upto a depth of 230 feet, after which he said boring can not be carried out further.About 1 inch of water supply was found at a depth of 150 feet. The casing i.e the pipe which is provided upto the rocks, is of 77 feet in length and 4.5 inches in diameter. We have to install a 1000 litre tank on the roof top which is 15 feet from the ground level and about 15 meters away from the borewell.

I have installed a 15 HP submersible pump (CRI) in my farm in Southern Tamil Nadu. This pump is installed in a 380 feet borewell that has an average yield of 3000 to 3600 litres per hour. The 15 HP pump was installed on basis of a wrong advice provided by the pump dealer as I was looking at installing rain gun and a rain gun required significant pressure. In hindsight a 5 or a 7.5 HP pump should have served the purpose
