The citizens of St. Marys are very fortunate that our four wells are capable of providing large quantities of water, free of bacteria and other contaminants. Two of the wells are located in a gravel formation in the ancient Teays River Valley System, while the other two are located in a limestone formation. Wells #1 and #2 are limestone wells in the Carl Jackson Well Field. Both are 270 feet deep and pump 1100 gallons per minute. Wells #4 and #5 are gravel wells in the Barrington Well Field. Well #4 is 320 feet deep and pumps 850 gallons per minute and well #5 is 354 feet deep and pumps 1200 gallons per minute.
Untreated well water pumped into the treatment plant goes through a complex, multi-stage treatment process that takes about 12 hours, producing a consistent supply of high quality drinking water. The treatment plant is a lime-soda ash softening facility; softening the water makes it ‘kinder‘ to appliances, machinery, and the human body.
The Water Treatment Plant Laboratory is Ohio EPA approved and contains all the various equipment needed to monitor the water. Lab Technicians, thoroughly trained and certified by Ohio EPA to do both chemical and bacteriological tests, check water quality at all stages of the treatment process to insure that the water is treated properly. Tests include pH, hardness, alkalinity, chlorine residual, and bacteriological. In addition to routine tests, we monitor for the presence of more than 130 complex chemical compounds. This monitoring, mandated by EPA and the Safe Drinking Water Act (SDWA), helps protect the health of the public.

Regular maintenance is a very important part of operating a public water supply. Personnel are charged with many tasks and projects in order to keep the treatment plant operating at peak levels. Examples include: preventative maintenance of treatment plant equipment, regular inspections of the wells and water towers, and many other activities.
Four full time operators staff the St. Marys Water Treatment Plant sixteen hours per day, seven days per week. One supervisor, a technical operations coordinator, a laboratory technician, a relief operator, and two maintenance men split time between the plant and other duties. All employees are Ohio EPA certified operators. The increasingly technical nature of Federal and State regulations requires continuing training on the part of all employees.
