The city of Dearborn was awarded a $7.5 million low-interest loan from the State of Michigan to continue the massive federally-mandated combined sewer overflow work that has been going on in our city for more than a decade.

This particular loan will go toward the sewer-separation project south of Wilson Street, east of Telegraph Road and north of the Rouge River, City Engineer Yunus Patel tells DeepsaidWhat. Construction is set to get underway in February. If all goes well, construction of this phase of the CSO product would wrap up in October.

Costs for this part of the project are expected to total about $12 million. These costs and interest on the loan, a 2.5 percent rate, will be paid down through the special CSO millage instituted in 2004. Any other project costs will be paid “using various funding sources”, the Dearborn Press & Guide quotes Dearborn finance officials as saying.

The CSO project is aimed at putting an end to the discharge of untreated sewage into the Rouge River. The cleanup is mandated by the federal Clean Water Act.

Those of you who have been following this project will recall that our elected Dearborn officials first chose to address the problem by approving spending on constructing multi-million gallon containment shafts able to store any excess drain water. But the implementation and construction has been a quagmire of engineering problems, followed by lawsuits.

So in 2010, Dearborn officials decided to abandon the containment shaft and go to sewer separation, which was one of the original ideas proposed nearly a decade ago but rejected for reasons we simply can’t recall. While a little more intrusive to vehicle traffic, separation is less expensive and results in new paved surfaces once the work is completed.

The Press and Guide says that according to the DEQ, from January through November 2011, Dearborn’s CSO Outfall 004, which services the area that will see work beginning in February, there were 27 reported overflow events, which released 45.7 million gallons of untreated combined sewage into the Rouge River. Prior to Dearborn beginning their CSO control program, the total average annual volume of overflows per year was approximately 929 million gallons.
