Hi,
My house construction (in 30x40 site) has started and now its at the foundation level. We had drilled a borewell and the information is as follows,
Borewell location : K.R.Puram (Mahadevapura), Bangalore East
Drilling time: Mid November, 2011
Depth of borewell : 650 feet
Depth of 6.5 ” casing : 80 feet
Depth of 10" PVC Casing pipe: 10 feet.
Yield data - I yield: 640 feet, 2.5".
On further drilling, boulders were found at 645 feet. and we continued to drill till 660 Feet.
It was meant to be used during the house construction. Now, before inserting pump we checked with a camera and found that the well has collapsed at 645 feet onwards and the depth of water we have is just 5 feet. Also looks like water source is connecting to another borewell, as water is not rising above 640 feet though we had 2.5" to 3" water during drilling.
Can you please advise whether drilling for another 100 to 200 feet will help?
Is it possible to install PVC filter pipe from 640 onwards using any method after re-drilling for another 100 t0 200 feet?
Any solution will be greatly appreciated.
Regards
Mahendra S
