Wisconsin Well Costs by Region

Central WI (sandstone): 150–350 feet in Mt. Simon-Elk Mound sandstone, $28–$48/ft. Eastern WI (Niagara Dolomite/limestone): 100–250 feet, $25–$42/ft. Northern WI (crystalline rock, glacial): 150–400 feet in granite and basalt, $32–$55/ft. Southwest WI (driftless area, sandstone): 100–300 feet, $25–$45/ft.

Wisconsin DNR Well Code

Wisconsin wells regulated by DNR under NR 812. Licensed well driller required. Well construction report (form 3300-23) must be filed. Minimum 25-foot setback from septic systems. Private wells require bacteriological testing before use.

Common Questions

Wisconsin residential wells typically cost $7,000–$16,000 installed. The range reflects depth variation — shorter sandstone wells in central WI cost less than deep northern Wisconsin crystalline rock wells.

Yes. DNR requires bacteriological (coliform) testing before a new well is put into service. Testing for nitrates is also strongly recommended, especially in agricultural areas.
