About this area's water Toledo City Of
Did you know
- Collins Park is the largest water-softening plant on Lake Erie and filters about 75 million gallons a day.
- Toledo's 2014 do-not-drink order cut off tap water for roughly half a million people for three days, the first big U.S. city shut down by an algal toxin.
- Toledo voters' 2019 Lake Erie Bill of Rights tried to give the lake legal standing; a federal judge struck it down the next year.
- The system serves parts of Lucas, Wood and Fulton counties in Ohio plus southern Monroe County, Michigan, about 500,000 people in all.

- 2014A western Lake Erie algal bloom pushed microcystin past the intake, forcing a do-not-drink order Aug 2-4 for 400,000 to 500,000 people.
- 2019Toledo voters passed the Lake Erie Bill of Rights charter amendment after the bloom crisis; a federal judge voided it the following year.

Treatment & pressure
How it is treated
Lake Erie water is coagulated and lime-softened at Collins Park, the largest water-softening plant on the lake, filtering about 75 million gallons a day; it then passes through biologically active filters supporting an ozone system and is chlorinated and fluoridated.
Water pressure
not published; no psi figure appears in city materials or the 2024 water quality report
What it costs
$6.49 per 1,000 gallons
Typical household bill about $25 a month for water.

Supply stress
The intake sits in western Lake Erie, the epicenter of seasonal harmful algal blooms. Ohio EPA's assessment calls the surface source susceptible, citing nearby sewage plants, combined sewer overflows, farm and urban runoff, dredge disposal and shipping spills. The 2014 crisis remains the defining risk.
Sewers
Sanitary
Toledo's Department of Public Utilities runs the sanitary sewers through its Sewer & Drainage and Water Reclamation divisions. 2026 residential sewer charges are $24.35/month fixed on a 5/8-inch meter plus $6.060 per 100 cf. CSO consent-decree figures not verified this pass.
Storm
Toledo bills a separate stormwater charge of $3.80 per month for single-family homes under the 2026 rate schedule; older parts of the city have combined sewers.
