About Us

The Rib Mountain Metropolitan Sewerage District (RMMSD), while  located in the Town of Rib Mountain, is not part of the local government of the Town of Rib Mountain. Instead, it is a single-purpose Municipal Corporation whose sole duty is to be a regional waste water treatment  facility in accordance with Chapter 200 of the Wisconsin State Statutes.


This facility was built in 1985 to treat the waste water from the  Village of Weston, the Village of Rothschild, the Village of  Kronenwetter, City of Mosinee and the Rib Mountain Sanitary District.  The RMMSD is governed by a 5 Member Commission.
