I have dug a borewell in Ashti in Wardha district of Maharashtra on the 19th of March 2012. The details are as follows:

1) Bore drilling - 7.25 "

2) Total depth - 380 feet

3) Water source 1" at 150 feet, 1" at 220 feet, 4" at 360 feet. (This is as per the bore machine operator)

4) The soil layers are - 1 to 40 ft black/soft soil, then 41 to 260 hard rock , 260 to 280 red soft soil, 280 to 380 hard porus rock i.e. black rock having white stone in between

5)  We put an inner casing with holes at about 140 feet from bottom, then casing for the top 45 feet.

Please help me with the following:

1) How much output can I get?

2) What type of pump is to be installed?

3) What should be the hp of the pump?

4) At what depth should the pump be installed?

5) Should we use a 2" or 3" out put pipe?

6) Should the output pipe to be used be GI or HDPE?

Please advise.
