Oregon city council on Monday approved a $6,278,000 contract with Peterson Construction Company for Phase I of the wastewater treatment plant’s secondary improvement project.

“The purpose of this project is to deal with wet weather,” said Public Service Director Paul Roman.

As part of the Ohio Environmental Protection Agency’s National Pollutant Discharge Elimination System (NPDES) permit, the city is required to increase the secondary treatment capacity of the wastewater treatment plant from 24 million gallons per day (MGD) to 36 MGD to eliminate secondary treatment bypasses and sanitary sewer collection overflows during wet weather.

“Unfortunately, we still get storm water in the sanitary sewers and we have to deal with that at the wastewater plant. Improving our secondary treatment at the plant will help eliminate any secondary bypasses to Lake Erie so it will definitely improve the lake,” said Roman.

The project consists of two phases that must be completed by December, 2017, he said.

Phase I involves equipment replacement, including two influent screens, three raw sewage pump motor drives, two blowers, air piping, air diffusers in aeration tanks and a dissolved oxygen control system, site restoration, and associated supervisory control and data acquisition upgrades, according to Roman.

“This equipment is really beyond it’s age. The plant was originally constructed in 1978. Most equipment typically has a 25-30 year life,” he said.

The Phase I project is included in the city’s 2013 Capital Improvement Project (CIP) budget and will be financed through the Ohio EPA Water Pollution Control Loan Fund supplemented with a grant and loan funding through the Ohio Public Works Commission.

Bids for the project were opened on Oct. 29.

Peterson Construction Company, of Wapakoneta, Ohio, was the low bidder followed by Mosser Construction, Inc., at $6,530,000, and Walbridge at $7,340,000.

“Peterson definitely had the lowest bid and certainly met the best bid criteria as well,” said Roman.

The engineer’s estimate for the project was $8,172,000.

Roman said there will be the need for a capital improvement charge to help pay for the loan. 

“That will need to be established in March,” he said.

The loan payments will be paid over a 20 year period, he added.

“The Northwest Sewer & Water District will also be building a storage facility with the wastewater treatment plant improvements. At the same time, we’re still continuing to do our sewer rehab throughout the city. The whole intention is to remove as much water from the sanitary,” said Roman. “But we know as much as we try, there will still be some storm water entering the sewer system.  That’s the reason for the treatment plant expansion work as well as the storage facility.”
