In Washington County, Wisconsin, which covers part of Milwaukee, we have measured 17,441 parcels on septic and 31,997 on sewer. That is a county measurement. We do not hold a septic count for Milwaukee on its own and this page does not estimate one. Milwaukee also extends into Waukesha County and Milwaukee County, which are reported separately below and are not included in that figure.
Milwaukee is a city in Washington, Waukesha and Milwaukee Counties, Wisconsin. The Census Bureau puts its internal point at 43.063348, -87.966695 and its land area at 96.17 square miles. 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.

We have not yet collected septic documents from Washington County, Wisconsin, so for a Milwaukee 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. The county is genuinely mixed: 17,441 of 49,438 classified parcels are on septic and the rest are sewered. Which side of that line a Milwaukee address falls on is worth establishing before anything else. The county publishes a records portal, but reaching the documents needs an account or a login, so budget for that step rather than expecting an open search.
