Michigan city’s CSO project slated for January 2012

August 2011, Vol. 66 No. 8

The city of Dearborn, MI, held a public meeting in June to propose sewer separation work to stop wastewater discharges in the Rouge River during heavy rains or spring thaw.

Dearborn’s current storm and sanitary systems share the same pipe infrastructure, which overloads the system during wet-weather events, leading to raw sewage discharge in the Rouge River at one of more than 20 outfall sites.

The upcoming projects will target six areas of the city for sewer separation, with construction scheduled to begin in January 2012. Each project is expected to take anywhere from 20 to 48 months, resulting in a 15-year target completion date.

The first area that will undergo sewer separation is bound by Telegraph Road, Cherry Hill, Martha Street and the Rouge River and is slated to begin in January with expected construction duration of 20 months. The estimated cost is $12.05 million.

The sewer separation work — projected to be more than $325 million — combined sewage overflow project has been in the works now for more than three decades. Previous solutions for meeting new federal water quality mandates while continuing regional efforts to clean up water flowing into the Rouge River have proved unsuccessful for Dearborn.
