DIVISION OF WASTEWATER

The City of Marysville Wastewater System serves the residents and businesses in the City as well as Milford Center, the Honda of America auto plants, and Southeastern Union County along Industrial Parkway.  The Water Reclamation Facility treats an average daily flow of approximately 4.0 million gallons per day (mgd).  The Water Reclamation Facility (WRF) is located outside of the City on Beecher-Gamble Road.  The WRF is staffed seven days a week, 24 hours per day.  The Superintendent, Rick Varner, can be reached at (937) 642-1036 weekdays from 8:00am to 4:30pm.

History

The original sewers in Marysville were installed in 1913.  At that time the system was comprised of about 13 miles of six or eight inch clay gravity lines and a small pond.  In 1932 the first anaerobic digester was built as well as Imhoff tanks and the treatment pond was enlarged.  In the fifties, two aeration tanks with agitating aerators were added as well as final clarifiers and sludge drying beds.

1964 brought the first large expansion with the addition of another larger primary anaerobic digester, conversion of the Imhoff tanks to primary clarifiers, grit removal system, one additional aeration tank, a blower building and blowers to provide aeration, an additional final clarifier, and disinfection facilities.

In 1982 construction began on the existing treatment plant.  The facility is a two-stage activated sludge plant with tertiary filters.  The facility included pretreatment, primary clarifiers, additional aeration tanks, intermediate clarifiers, second stage aeration tanks and blower building, final clarifiers, effluent pumping, tertiary sand filters, chlorine and chemical feed systems, an equalization basin, administration building with a laboratory, a secondary anaerobic digester, and new sludge drying beds.  This expansion brought the total design capacity to 2.3 mgd.

In 1989 work began on a 1.7 mgd Orbal oxidation ditch and an additional final clarifier.  This expansion was added as a second flow train and runs parallel with the old plant.  A small pump station was also built to split the flow before pretreatment with approximately 58% of the flow directed to the existing 2-stage facility and 42% to the Orbal facility.  This brought the total design capacity to 4.0 mgd.

Two belt filter presses were installed in 1995 to dewater digested solids.  The first anaerobic digester built in the 1930's was converted to a lime holding tank to store used lime from the City Water Treatment Plant to be dewatered along with wastewater biosolids.

In 2000, a new headworks building with influent pumps, grit removal, fine screens, and flow diversion structure was constructed.  This facility replaced the pretreatment building constructed in the early 1980's.

In 2003, the anaerobic digester was converted to an aerobic digester.  The digester was modified and placed in operation in 2005.

Collection System

The current sewer system is made up of approximately 126 miles of sewer lines.  This includes both gravity and force mains.  The sewers range from 6 to 60 inches in diameter.  The system also includes 18 lift stations and 2,218 manholes.

New Facilities

The City of Marysville, Ohio owns and operates their wastewater collection and treatment system.  The wastewater system serves the City's population of approximately 19,000 people, several major industries within the City's corporation limits, including Scotts Miracle-Gro Company, Nestle Corporation, Goodyear Tire and Rubber Co., Parker Hannifin Hydraulics, Univenture, and the Ohio Reformatory for Women (ORW), as well as several other outlying businesses and communities, including Honda of America Manufacturing, the Village of Milford Center, and flows from surrounding areas of Union County.

In 2004, the City completed its Wastewater Master Study.  The Master Study recommended that a new Water Reclamation Facility be constructed to replace the existing facility, which was nearing the end of its useful life, and was in dire need of upgrade/expansion.  The new facility was strategically located on Beecher-Gamble Road so that it could serve existing customers as well as potential future high growth areas.  It was designed to meet more stringent current and future regulations and to be readily expandable in 2-mgd modules in order to meet future needs cost-effectively and expeditiously.

The wastewater conveyance system was designed to eliminate numerous lift stations throughout the existing collection system and minimize the number of future pump stations in order to increase reliability and reduce maintenance costs.
