About this area's water
Did you know
- At $72.00 a quarter for 22,500 gallons, Minster has the lowest water bill of the 71 jurisdictions in the 2026 rate survey it publishes - less than half the $172.15 survey average and about a sixth of the $433.65 high.
- A 90-to-100-foot slab of glacial till separates the ground surface from Minster's aquifer, and the wells are cased through more than 90 feet of it, which is why Ohio EPA calls the source low-susceptibility.
- The village's own water quality report spells the buried valley its wells tap the "Taeys River Valley"; the preglacial river is normally spelled Teays.
- Minster's sewage plant is built for 1.75 million gallons a day in a village of about 3,000 people, because it also takes industrial flow - the village is home to a Dannon yogurt plant described as one of the largest in…
- How many wells Minster has depends on who you ask: five in the 2025 water quality report, seven on the village's water department page, and eight active wells in EPA's facility inventory.

- 1832Settlement platted as Stallostown, after founder Francis J. Stallo.

Treatment & pressure
How it is treated
Groundwater from bedrock wells drawing on a carbonate aquifer that the village's CCR places in the "Taeys River Valley" (the usual spelling of the preglacial valley is Teays). Water sits more than 40 feet below the surface and the wells are cased to more than 90 feet. Sources disagree on how many…

Water pressure
No psi figure is published. Distribution pressure is carried by high-service pumps and the two elevated storage tanks (250,000 and 750,000 gallons) listed as active in EPA's…

Supply stress
Ohio EPA rates the aquifer serving Minster as having low susceptibility to contamination: a 90-to-100-foot confining layer of glacial till lies between the ground surface and the carbonate aquifer, and the village's wells are cased to more than 90 feet below the land surface. The village keeps an emergency interconnection with New Bremen…

Sanitary
The village owns and operates its own wastewater treatment plant at 155 West First Street, able to treat up to 1.75 million gallons a day of combined domestic and industrial flow; it processed roughly 1.36 MGD on average during 2019. The process is an extended-aeration orbital system: screening, equalization, primary settling, extended…
