Treatment & pressure
How it is treated
Blanchard River water is pumped into two upground reservoirs east of the city, with a direct river intake as backup; EPA classifies Findlay as a surface-water system. The plant's specific treatment train is not confirmed in accessible sources.
Water pressure
not published; no citywide average psi figure or pressure-zone map was found, and the city website blocks automated access.
What it costs
Rate increase effective Jan 1, 2024, about $70/year more for an average two-person household. No verifiable per-unit rate or fixed charge was found.
Water quality & impurities
EPA compliance record
Lead at the tap: 90th-percentile result 2.1 ppb in 2025 (action level 15 ppb).
EPA record: no health-based violations since 2015.
1 violation of any kind logged since 2020, 1 of them paperwork (monitoring, reporting, public notice or consumer report).
Supply stress
Findlay's reservoirs and river intake sit in a flood-prone Blanchard River corridor, and the city has pursued river flood-mitigation work. Specific supply-capacity, drought, algal or contamination pressures could not be confirmed in accessible sources.
Sewers
Sanitary
The city operates its own wastewater treatment plant, but its rated capacity, average flow, receiving stream and any combined-sewer or consent-decree status could not be confirmed; the city website blocks automated access.
