The Great Lakes Water Authority (GLWA)/ Detroit Water and Sewerage Department (DWSD) owns and operates one of the larger wastewater treatment plants (WWTP) in the United States, serving the City of Detroit and 76 suburban communities. The WWTP treats approximately 650 million gallons of wastewater per day on average, making it the largest discharger of treated wastewater to Michigan waters falling under the permitting authority of the EGLE's Water Resources Division. In addition, because this WWTP serves significant combined sewer areas, the ability to reduce, store and treat wet weather flows is critical. Due to the critical importance of the WWTP to 3 million Michiganders relying on the plant and its associated 3,400 miles of sanitary sewer lines and other appurtenances, EGLE has created this web page to direct citizens to various documents and other information available regarding the GLWA Water Resource Recovery Facility (WRRF) operations and compliance with state law requirements. All publicly available documents can be found at MiWaters Explorer in the documents section for the GLWA WRRF.  Please contact the EGLE Freedom of Information Act Coordinator to seek additional records that may be of interest.
