The main goal of the City of St. Marys Water Department is to provide safe and reliable drinking water services to the citizens and businesses of St. Marys at competitive rates. Water supply, treatment, and delivery to the City of St. Marys and surrounding area is a vital function of the City. St. Marys’ citizens first addressed drinking water quality in the 1890s when the first water supply facility was built. Today, our water treatment plant delivers the safest water possible to over 10,000 people.
Well water pumped into the Water Treatment Plant goes through a complex, multi-stage treatment process that takes about twelve hours, producing a consistent supply of high quality drinking water. Laboratory tests are performed routinely each day to control and ensure that each process is operating at peak levels. Two water towers, with a combined capacity of 1,250,000 gallons, store treated water for the system, controlling water pressure as well as providing fire protection. The water distribution system consists of approximately 76.76 miles of lines, 1,747 valves, and 576 fire hydrants. The system delivers drinking water to residential, commercial, and industrial customers in the City of St. Marys and other areas bordering Grand Lake St. Marys.
The City of St. Marys has established long range plans and goals that guide the improvements necessary to maintain drinking water quality and improve the reliability of services provided to consumers. These plans and goals are reviewed each year and adjusted as needed. Over the years, these plans have resulted in the regular replacement of essential equipment, the drilling of a new well to ensure a continued supply of water, construction of a second water tower, installation of major water line loops and interconnections that improve the flow of drinking water throughout the City, extending water services to new areas, and purchasing property for the time when a new treatment facility is needed.
