Oregon city council earlier this month approved a $382,000 contract for engineering services for Phase I of the wastewater treatment plant’s secondary improvement project.
The services provided by Jones & Henry Engineers, Ltd., of Toledo, include the review and approval of shop drawing submittals; the response to requests for information from the contractor; the review of monthly pay requests; the negotiation and preparation of change orders; the administration of monthly construction meetings, and the preparation of record drawings.
The firm will also provide a Resident Project Representative to monitor the contractor’s activities during the time work on the plant is occurring.
“They are the designer of the project,” Public Service Director Paul Roman said of Jones & Henry Engineers. “They’ve done a very good job. It is traditional that we hire the same designer for construction engineering and inspection.”
Council had also approved a $6.2 million contract with Peterson Construction Company for furnishing labor, materials and equipment for the $16 million project.
Peterson has not previously done work for the city, according to Roman. “Jones and Henry gives them a very high recommendation. There is no doubt in my mind they are the lowest and best bid.”
The improvements will eliminate secondary treatment bypasses and sanitary sewer collection system overflows during wet weather events.
The project consists of two phases that must be completed by December, 2017.
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.
Phase 2 improvements consist of new final clarifier with associated secondary sludge pumping facilities, aeration tank improvements consisting primarily of replacement of stop plates and slide gates, disinfection improvements consisting of replacement of the chlorine feed and safety equipment, effluent pump replacement and improvements, site restoration, and associated Supervisory Control and Data Acquisition upgrades.
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.
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.
Roman said he revised the financial plan of the project, which will be paid over a 20 year period.
“Originally in August this year, I gave a financial plan to council to give a brief overview. There will be the need for a capital improvement charge to pay for the loan of this project. That will need to be established at some time in March,” he said.
