The City of Mansfield Water Repair Department is located within the City Service Complex located at 480 Park Avenue East. Hours of operation are 7:00am – 3:30pm Monday thru Friday. 


The City of Mansfield Water Repair Department repairs and maintains over 300 miles of underground water mains that distributes our city’s water supply.


Water Repair


There are over 3,400 water main valves which enables us to shut down and repair water mains in particular areas thus avoiding total loss of water service to the city.


The City of Mansfield has 2290 water hydrants. Their primary function is for the supply of water for fire protection. The fire hydrants ease of operation and high flow capabilities make it a natural for use in flushing distribution system main water lines.


We have over 24,000 water service taps which supplies water to residential homes and businesses throughout the city.


The water repair department’s primary job duties include locating and repairing water main lines ranging in size from 1” to 30”.  Repairing and maintaining water main valves.  The repair of water hydrants damage by collision or malfunctioning of valves.   The installation of water service taps for homes and businesses.


To protect our water lines remember to always dig safely.


 By law, everyone MUST contact the Ohio Utilities Protection Service, 8-1-1 or 1-800-362-2764, at least 48 hours but no more than 10 working days (excluding weekends and legal holidays) before beginning ANY digging project.

Utility Collections is responsible for billing and collecting water and sewer accounts, collection of parking citations, and other related City services.

Water and sewer accounts can be paid in person at the Utility Collections Office by mail or by electronic funds transfer through a customer's bank.

Water and sewer accounts are billed monthly only for water that passes through your meter. If you use a lot of water outside or have a swimming pool it would be to your advantage to purchase a sewer deduct meter. The sewer deduct meter would reduce the cost of sewer usage for any "outside watering"

Any water leak, no matter how large or small can increase your monthly bill. The most common undetected leak is a running toilet. If you discover a leak or notice a substantial increase in your monthly bill, contact our customer service department at (419) 755-9785 and they will be glad to assist you.

Program objectives

  • Prevent industrial pollutant discharges from passing through municipal wastewater treatment plants untreated.
  • Protect treatment plants from the threat posed by untreated industrial wastewater
  • To improve the quality of effluents and sludges
  • Educate industrial users of the affects of toxic pollutant discharges


Currently The City of Mansfield monitors seventy-four industries in the Mansfield and surrounding areas.




1902 The first ‘contact filter type’ sewage treatment plant was constructed by the City.
1918 An additional plant of the trickling filter type was built to treat the sewage from the low level areas in Mansfield.
1936 Both plants were replaced by one new plant.
1939 A report was submitted to the City containing recommendations for collection and treatment of sewage that was not implemented due to the defense period, shortage of manpower, materials and the intervention of World War II.
1942 The small South Boulevards sewage plant was built.
1945 Due to equipment wearing out, increase of population and other factors, the City’s facilities for sewage treatment became inadequate.
1948 The City acquired the South Boulevards plant.
1953 Floyd G. Brown and Associates of Marion Ohio were retained as consulting engineers. A review of the 1939 report was done and recommendations for improvements begin.
1960 The new four MGD waste treatment plant was completed.
1984 Plant improvements began and were completed in 1987.

The Mansfield Water Treatment Plant receives a daily blend of raw water from both a surface reservoir and 10 wells. Clearfork Reservoir is a 4.5 billion gallon lake, located southwest of the treatment plant. The intakes at the gatehouse permit water to be drawn from 4 levels within the lake, based on seasonal affects on water quality. Lake water flows to a lowlift pumping facility, which can deliver up to 25 million gallons per day (MGD) of surface water to the plant. Potassium Permanganate is added at the intake for zebra mussel control. In addition to the reservoir, there are ten wells, located within a two mile radius of the plant, capable of supplying up to 10 MGD to the plant. Five wells north of the plant, designated by Ohio EPA as under the influence of surface water, enter the plant at the same location as the reservoir water and receive full treatment. The remaining five wells, designated by Ohio EPA as not under the influence of surface water, are blended at the plant, ahead of our 16 rapid sand filters.


The reservoir and north well water are first treated at the plant with activated carbon, for taste and odor control, and alum polymer for coagulation. The water then flows into four primary mixing basins, with a total capacity 500,000 gallons, then into four secondary settling basins with a total capacity of 2.5 million gallons, for settling and clarification.


When the water leaves the settling basins, it is blended with the south well water, and flows to the 16 rapid sand filters. Pre-chlorine is added just ahead of the filters for disinfection. The water is filtered through a combination of anthracite coal, sand, and a mixture of support gravel. The filters remove any remaining suspended matter in the water. After the water passes through the filters, final chlorine is added for disinfection, and sodium hydroxide is added for stability. At the end of treatment, a phosphate silicate corrosion inhibitor is added for further stabilization.


The water flows into two pump houses where it is pumped to the City of Mansfield. The pump houses can deliver up to 25 MGD, if needed. The finished water is stored in two elevated tanks, Straub (2 million gallons) and Shaker (500,000 gallons), and in a 12 million gallon under ground concrete reservoir.


Our plant operators monitor and control the system using a programmable logic controller (PLC) based computer system. PLC’s are also used to monitor the reservoir system, wells, and finished water storage.



Additional Information

  • The water plant is classified by Ohio EPA as a Class IV system, based on plant size, types of treatment, and population served.
  • The water plant has an Ohio EPA approved chemical and bacteriological laboratory.
  • The water plant owns and maintains all power lines, poles, transformers, and substations throughout the treatment system.
  • The plant has an Ohio EPA approved corrosion control plan.
