Frequently Asked Questions — Well Permit

Who issues well permits in Wisconsin?

Well permits in Wisconsin are typically issued by the county. The Wisconsin DNR sets statewide standards under NR 812, but county agencies handle day-to-day permitting and inspections. The well must also comply with local zoning setback requirements. All well drilling must be performed by a DNR-licensed well driller.

What are the setback requirements for a well in Wisconsin?

Wisconsin requires minimum setback distances for wells under NR 812: at least 25 feet from a sewer line, 50 feet from a septic tank, 75 feet from an absorption field, and 100 feet from a manure storage area. Distance from property lines and buildings also applies. Your county may have additional setback requirements.

Do I need to seal an old well in Wisconsin?

Yes. Wisconsin law requires that unused or abandoned wells be properly sealed (filled and capped) by a licensed well driller to prevent groundwater contamination. Property owners are responsible for having abandoned wells sealed. When selling property, well disclosure is required, and unsealed wells must be addressed.
