MACOMB TOWNSHIP — A $3.8 million sewer project is underway along 23 Mile Road in Macomb Township, between Romeo Plank and Hayes roads.

The project means that the far right westbound lane of 23 Mile Road will be closed in that stretch for the duration of the project, which is expected to be approximately three months.

Project Manager Steve Siklich said there will also be a one-week intermittent lane closure at the intersection of 23 Mile and Hayes sometime in April.

“There’s a structure right in the middle of that intersection, so we’ll need to close a couple of the lanes in each direction in order to access the structure,” Siklich said.

A 2014 investigation into sewer pipes throughout Macomb County identified the 23 Mile sewer as an area to repair since it has been in the ground since the 1970s, Siklich added.

“It’s not in eminent danger of collapse, but this will extend its life for another 50 years. I think we’re right on track with where we want to be for a complete rehab with this,” Siklich said.

According to a press release from the county’s Public Works Commission, the project will consist of the installation of 7,100 linear feet of resin-saturated polyester liner inside existing sewers that are showing early signs of deterioration from hydrogen sulfide corrosion. The sewer lining will be inserted into the sewers 15 to 25 feet below ground.

“You end up with a pipe inside the old pipe, which is actually stronger than the existing pipe,” Siklich said.

To minimize traffic impact, crews will be using trenchless technologies to complete the project. All driveways will also be maintained despite there being some above-ground piping work, but there will be ramping across all driveways, Siklich added.

“As far as construction is concerned, this is probably the least invasive project you could actually have for a sewer repair of this nature,” Siklich said. “If there are no unforeseen issues, everything will be done at the surface through these trenchless methods. There will be no digging required, or very minimal for rehab.”

In addition to the sewer lining work, 15 sewer manhole structures will receive extensive rehabilitation throughout the county.

The project is being financed through a loan from the State Revolving Fund with a 2.5 percent interest rate.

Siklich said construction is estimated to be completed around the end of June.
