This is Mr. Zaib from Rawalpindi, Pakistan. Sorry to say but my English is not very good so do pardon me in advance if you can't get my point. We built our new home last year and did a 130 feet deep bore well in March 2016. Water comes out in the bore well at twice stages ( at 55 feet and 78 feet deep) In the begging there was sufficient water in the bore well and whenever we switched On the pump then the water comes out from the bore well for more than 90 minutes contentiously ( non stop ). But after 8 months ( Since November 2016 till yet ) suddenly the water capacity of bore well reduced at once and whenever we switch on the pump then water comes of the bore well only for just 6 to 8 minutes. And if we wait for exact 1 hour and then switch on the pump again then water comes out from the bore 6 to 8 minutes. I mean that each time, after wait for 1 hour water comes from bore well for just 6 to 8 minutes. Since last 20 days , after every 5 or 6 days, sometime when we switch on the pump then ( mostly at afternoon and evening times ) there come out some clay with water and if happen so then the water comes out from the bore well for around 15 to 20 minutes non stop. ( remember that here was heavy rainy seasons happened from June 2017 to late August 2017) I tried my best to explain my problem. I want to know the reason of this problem and how to solve this issue. I shall be very thankful to all my Indian friends if any of them tell me the solution.
