Cost to drill a 500 ft well: $19,100–$66,200

A 500 ft drilled water well costs $19,100–$66,200 finished, with a midpoint of $42,600, at national driller rates. Drilling and casing alone run $16,500–$55,100; the pump, pressure tank, and hookup make up the rest. It is a typical depth in New Hampshire, Arizona and Connecticut, where the middle half of reported wells spans 500 ft.1,2,3,4,5,6,7,8,9

Cross-section of a 500 ft well with casing to about 330 ft

The borehole costs $12,500–$37,500 at 500 ft. Casing, the pipe that lines the upper borehole, is assumed to run to about 330 ft here; your driller sets the real casing depth from the geology they hit.

Common questions

Is 500 ft deep for a water well?

500 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 500 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 500 ft well?

Going to 600 ft raises the midpoint from $42,600 to $49,400. Stopping at 400 ft brings it down to $35,900. The driller cannot promise a depth in advance, so a quote should state the per-foot rate for any footage beyond the estimate.
