Well and Septic Contractors in Wisconsin, by county

This page lists every Wisconsin county that has its own page of well and septic contractors, with the number of businesses on each. Well drillers, pump installers, septic pumpers and septic installers are all included, and many businesses do more than one of these jobs.

Counties with fewer than 3 listed businesses share the page of the nearest county, so every listing in the state appears somewhere. Each county page ranks its businesses by rating and review count and shows which jobs each one names, from well drilling and pump repair to septic pumping, inspections, holding tanks and soil testing.

Before you call, it helps to know which job you need. A new well and a failed pump are well jobs, licensed by the Wisconsin DNR. The three-year septic inspection, routine pumping and holding tank service are septic jobs, and a new septic system starts with a soil test by a certified soil tester. The service pages linked from every county page group the businesses by job across the whole state.
