The borehole costs $20,000–$60,000 at 800 ft. Casing, the pipe that lines the upper borehole, is assumed to run to about 520 ft here; your driller sets the real casing depth from the geology they hit.

Where wells reach 800 ft

No state with records has 800 ft inside its middle half of domestic wells. The deepest quarter of wells comes closest in Arizona (600 ft), New Hampshire (540 ft), Colorado (500 ft), Connecticut (500 ft), Massachusetts (500 ft). A 800 ft well usually means a deep aquifer or a dry first attempt.

Common questions

Is 800 ft deep for a water well?

800 ft is deeper than the median domestic well in 35 of the 35 states that publish completion reports in bulk. The national median is 200 ft. Whether 800 ft is normal where you live depends on the aquifer, so compare it with the county table on your state page.

How much more does a deeper well cost than a 800 ft well?

Stopping at 600 ft brings it down to $49,400. The driller cannot promise a depth in advance, so a quote should state the per-foot rate for any footage beyond the estimate.
