The Fond du Lac Regional Wastewater Treatment & Resource Recovery Facility serves the City of Fond du Lac and thirteen neighboring communities. Every day the wastewater treatment plant treats approximately 7-8 million gallons of wastewater in order to protect public health and the environment.

The 2008 project was the fifth major project on the current site including projects in 1927, 1949, 1964, and 1975. Elements of the 1949, 1964 and 1975 facilities were reused to provide added features at little or no cost.

Facilities from the 1949 plant as well as the 1974 plant were retained to provide additional treatment capacity for abnormally high flows at a low cost to system users. These facilities provide the necessary treatment to comply with permit requirements. During the flood of 2008 this facility provided effective treatment for 32mgd of flow for a 24 hour period, allowing for 34 mgd of flow routed through the plant to meet all permit requirements. The facility returned to normal operations one day after the storm surge subsided. Digestion facilities originally constructed in 1964 were recommissioned with the 2008 project to provide biosolids digestion and storage.

The City's first wastewater treatment plant, portions of which still serve the City as the Doty Street Pumping Station, was placed in service in 1913 about 1,500 feet from the current site.  The most recent update was in 2008 which makes it the fifth major project completed on the current site, including projects in 1928, 1949, 1964, 1975, and 2008.  Many elements of the 1949, 1964 and 1975 facilities were adaptively reused for the 2008 plant upgrade to provide added features at little or no cost.  These adaptive reuses save the rate payer millions of potential additional costs.

The City’s first wastewater treatment plant was placed into service in 1913. A portion of the plant still in use today is the Doty Street Pumping Station, located about 1,500 feet from the current site.
Our staff is comprised of a Superintendent, Assistant Superintendent, Facilities & Maintenance Foreman, Industrial Pretreatment Coordinator, Administrative Assistant, Wastewater Treatment Operators, Maintenance Mechanics, Lead Laboratory Analyst , Lab Technicians, and Sampling & Monitoring Technician.
