Hello,
We have a 6" borewell used for domestic purpose, which was about 200 feet deep and sheet metal casing pipe till 32 feet drilled in the year 2003. Recently we felt that sewage water has entered the borewell. The line is about 8 to 10 feet away from our borewell. Last week we got the borewell cleaned by using salt, washing powder and bleaching powder with the help of borewell cleaners.
Now we are planning to replace the existing sheet metal casing with pvc casing or inserting smaller size pvc. Can you please suggest how to go about this process?
