About this area's water
Did you know
- Tontogany buys 100% of its drinking water from the City of Bowling Green and simply redistributes it — it has no wells or treatment plant of its own.
- Bowling Green stores its Maumee River water in a 170-million-gallon above-ground reservoir before treating it through two parallel systems: conventional filtration and reverse-osmosis membrane treatment.
- In August 2026, Bowling Green had to send a formal Drinking Water Notice after 29 days of low corrosion-control chemical dosing earlier that year — not an emergency, but it required extra lead and copper testing.
- Tontogany bills a separate monthly 'water line maintenance fee' that scales from $15 for a household meter up to $600 for a 6-inch industrial meter, on top of its metered consumption rate.

Supply stress
Tontogany has no water source of its own — it is entirely dependent on Bowling Green's Maumee River supply and treatment, and on the Northwestern Water & Sewer District for sewer billing. Any Bowling Green supply or treatment problem, such as the confirmed 2026 corrosion-control lapse, passes directly to Tontogany customers. This framing…
Sewers
Sanitary
Tontogany does not operate its own sanitary sewer treatment plant; the village bills residents on behalf of the Northwestern Water & Sewer District for sewer service — confirmed directly on the village's own utilities page. No specific wastewater plant name, capacity, or consent decree was found anywhere.
