Septic permitting and record keeping happen at the county level, not the city level, which is why every figure below is attributed to the county and linked back to the county page it came from.

Our collection for Columbia County, Wisconsin is small, at 32 septic records. Treat it as a starting point for a Columbus property rather than a search that settles the question. The county is genuinely mixed: 11,130 of 22,193 classified parcels are on septic and the rest are sewered. Which side of that line a Columbus address falls on is worth establishing before anything else. The county publishes a records portal that we were able to search without creating an account, which makes checking a specific parcel something you can do yourself in a few minutes.
