QUESTION
380 ft tube well failure in Bikaner, Rajasthan - Need to know the potential problems and the contact details of experts who could help

My father has a farm at Distt. Kulayat in Bikaner, Rajasthan. He dug a borewell at the farm couple of years ago & there was good water supply, however when the supply suddenly stopped, somebody recommended he uses acid to desilt the pipe & when that was done there was massive supply of water for a day thereafter huge silt & rocks came out & the pump stopped. Hypothesis was that the acid actually destroyed the metal pipes. Later, they could not dig out the motor or the pipes from the site.

Other neighboring farms have dug borewells & got water at 270-370 ft levels.

Basis these experiences, we recently dug a new borewell at the site near to the earlier one, with the following stats:

1) Borewell was drilled using a inch by hydraulic rig.

2) Hole was dug first 14" & later for 22" wide.

3) 11" Cement pipe with round holes of 4mm :800 holes/16ft pipe were installed till 380feet.

5) We filled in concrete/gravel for the filtration in between the cement pipe & the earth wall.

6) Post piping, we checked for water level & we struck it at 270ft first (Self testing by putting in a plastic wire with heavy wt)

7) A Hydrologist report of this area states that there is a good water zone between 270-370ft

After this installation, we tried to pump up water but to our disdain there was very less water discharge. It was almost 10% ofthe expectation & not sufficient for farming puposes.

Can anybody help? What should we do? What could be the problem?

My father is thinking about taking out the delivery pipe & using Acid to clear the way to check for water again. Will this work? We need an urgent addressal to this situation.

Kindly provide the contact information of suitable consultants who will be able to help us resolve the issue favorably.
