We have not yet collected septic documents from Clark County, Wisconsin, so for a Colby property the county's own file is currently the only route. This page is about getting you to it, not about pretending we hold something we do not. Of the parcels we have classified in the county, most are on septic rather than sewer (9,940 of 15,155). A property near Colby is more likely than not to have its own system. 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.
