The Downriver Wastewater Treatment Facility (DWTF) utilizes preliminary, primary and state of the art Ultra Violet (UV) disinfection treatment processes to treat sewage prior to discharging treated effluent to the Trenton Channel of the Detroit River. The facility is located on a 34-acre site in Wyandotte Michigan and has 80 employees. The DWTF can provide treatment for an influent flow rate of up to 225 MGD. The primary and secondary treatment processes are designed to treat maximum flow rate of 150 and 125 MGD, respectively. The facility is designed such that flow cannot bypass both primary and secondary treatment processes. All flows undergo disinfection prior to discharge to the Detroit River.
