A large drill rig, truck and crew are needed to actually drill the hole. It can take many days.
Then, because the water is so deep, a motorized pump must be installed. The water is simply too heavy to lift from that depth with a hand pump. Diesel generators, large electric pumps, piping, storage tanks and housing for it all can drive the cost up to $30,000 or more. But, since these very large systems serve so many people, they are still quite cost effective. In fact, some of these large systems can serve over 3,000 people!
We only partner with established drillers with a lot of experience for these complicated projects.
