Cost to drill a 300 ft well: $12,800–$45,400

A 300 ft drilled water well costs $12,800–$45,400 finished, with a midpoint of $29,100, at national driller rates. Drilling and casing alone run $10,200–$34,300; the pump, pressure tank, and hookup make up the rest. It is a typical depth in Maine, California and Colorado, where the middle half of reported wells spans 300 ft.1,2,3,4,5,6,7,8,9

The borehole costs $7,500–$22,500 at 300 ft. Casing, the pipe that lines the upper borehole, is assumed to run to about 200 ft here; your driller sets the real casing depth from the geology they hit.

Common questions

Is 300 ft deep for a water well?

300 ft is deeper than the median domestic well in 26 of the 35 states that publish completion reports in bulk. The national median is 200 ft. Whether 300 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 300 ft well?

Going to 400 ft raises the midpoint from $29,100 to $35,900. Stopping at 200 ft brings it down to $22,300. The driller cannot promise a depth in advance, so a quote should state the per-foot rate for any footage beyond the estimate.
