In 2016, Great Lakes Water Authority awarded CDM Constructors, Inc. Contract number PC – 797. The project was a Progressive Design Build for the Rouge River Outfall Disinfection Project. The Rouge River Outfall Disinfection Project is required to meet MDEQ requirements for 100% disinfection of wet weather flow discharged from the Detroit WWTP. This project included modifications to the WWTP in order to achieve proper flow control and disinfection during dry and wet weather operating conditions. The Detroit WWTP currently serves nearly one-third of Michigan’s population and is one of the largest wastewater treatment plants in the United States.
Commercial Contracting Corporation is responsible for all concrete related to this project that spans over four different areas including a new chemical facility and access shafts to the existing waste water conduits.
The project was completed in January 2019. The wastewater treatment plant is currently able to completely disinfect and de-chlorinate all treated wastewater prior to being discharged.
