About this area's water

Did you know
- Bryan's supply comes from seven artesian wells averaging just 131 feet deep, pumping about 1.5 million gallons a day at roughly 2,000 gallons per minute - shallow, self-pressurizing water that needs only aeration…
- The city charges its own residents a dedicated groundwater-protection surcharge - 75 cents a month residential, a dollar commercial - to fund source water protection.
- Bryan asked the federal government in 2007 to declare the Michindoh aquifer a sole source aquifer for a nine-county tri-state area; U.S. EPA suspended the petition in 2013 over data gaps and it has never been designated.
- Water is only part of the operation: Bryan Municipal Utilities also runs the city's electric system, including a hydroelectric plant on the Auglaize River and a municipal solar field.
History6
- 1940City wastewater treatment plant built (0.8 MGD original design), later expanded to a 3.1 MGD average design flow.

Treatment & pressure
How it is treated
Groundwater only. BMU's drinking-water page describes seven artesian wells averaging 131 feet deep, pumping about 1.5 million gallons a day at roughly 2,000 gallons per minute (the 2025 CCR describes six wells drawing from the aquifer). Treatment is gravity aeration to oxidize iron and strip carbon…

Supply stress
Bryan is entirely dependent on one groundwater source: the city says flatly that it is 'extremely dependent on our ground water supply' from the Michindoh Glacial Aquifer, which also supplies most of Williams County and parts of Defiance and Fulton counties plus adjacent Michigan and Indiana. Bryan petitioned U.S. EPA in 2007 for federal…
Sewers
Sanitary
City of Bryan WWTP at 1521 Evansport Road, built in 1940 and last upgraded in 2018, with an average design flow of 3.1 MGD (the city's own page says 3.14 MGD design, expanded from 0.8 MGD) and a 7.0 MGD peak hydraulic capacity; average flow is about 2 MGD. It serves the city plus Pulaski and Jefferson townships through seven satellite…
Storm
Bryan has 100% separated sewers per the 2024 Ohio EPA NPDES fact sheet, so storm flow does not enter the wastewater plant. No separate stormwater utility fee was found in city or BMU rate material.
