Construction for the final piece of Port Huron’s massive sewer-separation project is expected to begin sometime this month.

The project comes with a total price tag approaching $2 million and more than two decades after the state first ordered the city to stop close to 309 million gallons of combined sewage and stormwater from discharging into the Black and St. Clair rivers each year.

Eighteen other overflow points have already been completed as part of the effort — the last being the $5.4 million separation construction on Nern Street five years ago. A bid for the 19th location, near the site of the abandoned Blue Water Bridge Plaza expansion project, was approved by City Council in March.

Public Works Director Eric Witter said the city initially intended the work to start in 2019 after officials backed a deal the year prior to split cost of construction with the Michigan Department of Transportation.

“We lost the year. We anticipated it starting last year in April,” he said. “But we had to secure some easement from private properties. With that delay, it got pushed back.”

At the end of March, Witter said some construction-related meetings remained, adding that they’d be via conference calls because of the coronavirus outbreak.

“We also have to have coordination meetings with MDOT and some of the business owners,” he said.

However, Witter said they didn’t anticipate it to halt the project itself with completion anticipated by November or December.
