The Milwaukee Metropolitan Sewerage District (MMSD) operates from two budgets, one for capital projects -- primarily construction projects -- and another for the operation and maintenance expenses, mostly related to the day-to-day collection, conveyance, and treatment of wastewater. We do not handle direct customer billing. In effect, we're a wholesaler, whereby we send bills to the twenty-eight communities we serve, and the communities are the retailers handling direct customer billing.

The capital budget is funded primarily through capital charges such as property taxes. Money for our operations and maintenance budget is collected mainly through sewer user charges that individual customers pay based on use. Most communities bill these fees as part of their water bills.

Total sewer bills for your home or business also include charges from the community where you are located, since all the communities we serve own and operate their sewer systems that drain into the regional sewer system.
