Hi,

We have an query regarding compression pump / submersible pump for domestic use in our native place. We have shallow installed which is currently working via Hand pump. The shallow / bore well is 600 feet deep, with 70 - 80ft 4in pipe and remaining 520-530 ft in 2in pipe. During summer water levels go below 70 ft. This makes the handpump very difficult to operate.

Plumbers are suggesting drilling a new shallow with 4in upto 200 ft and then installing submersible pump. This is very costly proposition, given we already have an installation. Use is fully domestic. We were exploring compression pump, but the plumber suggested that this may lead to the underground shallow pipe even bursting - however a friend of ours, a chartered civil engineer, suggests that compression pump is fully safe, provided we select the correct horsepower. In this regard we request your help and technical expertise to understand what would be the right way forward. Appreciate a call or email.

Thanks
