Who regulates well drilling in Wisconsin?
The Wisconsin Department of Natural Resources (DNR) regulates well drilling under NR 812. This is different from most construction trades which are regulated by DSPS. The DNR oversees well construction standards to protect groundwater quality.
Can a homeowner drill their own well in Wisconsin?
No. Well construction must be performed by a DNR-licensed Well Driller. Wisconsin takes groundwater protection seriously, and improper well construction can contaminate aquifers affecting entire communities.
How much does a well drilling license cost in Wisconsin?
The initial license fee is $100 and annual renewal is $50. You must also carry liability insurance. The total investment including exam prep and insurance typically runs $500-$1,000 in the first year.
