Who We Serve

Today’s District covers nearly 100 square miles of Winnebago County. It serves around 240,000 people in the communities of Rockford, Loves Park, Machesney Park, Roscoe, Cherry Valley, New Milford, Winnebago, and a small portion of Rockton. Except for several private collection systems, the District owns and maintains all sanitary sewerage collection facilities within its boundaries. The District’s approximately 1,100-mile long network of buried sewers conveys wastewater from industrial sites, other businesses, and residences to the treatment plant in southeast Rockford.
