About this area's water

Did you know
- Toronto, Ohio was originally Newburg Landing, then Sloane's Station after the railroad arrived in 1856, before incorporating in 1881 as Toronto — named for Toronto, Ontario at the suggestion of a local fire-clay…
- Water and sewer are billed at identical rates, so every gallon is effectively charged twice: a 10,000-gallon month costs $136.00 for water and another $136.00 for sewage.
- The city keeps an emergency interconnection with the Jefferson County Water and Sewer District as a backup supply, but has not needed to use it in any recently reported year.
- Titanium Metals Corporation, which arrived in 1957, is the city's major employer — the last chapter of an industrial run that included sewer pipe, terra cotta, paving brick, glass, coal mining, and the American China…
- Toronto sells water wholesale beyond its own borders: its downstream service population of nearly 25,000 is more than four times the roughly 5,700 people inside the city.
History6
- 1856The Cleveland-Pittsburgh Railroad reached the village, then known as Newburg (or Newberg Landing); it was subsequently renamed Sloane's Station for William B. Sloane, who donated land for the station.
- 1881The village incorporated under the name Toronto, after Toronto, Ontario. The name was suggested by pioneer manufacturer Thomas M. Daniels, whose business associate W. F. Dunsbaugh — chief stockholder…
- 1931Toronto incorporated as a city; Harold Smith became its first mayor, and the youngest in the state.
- 1957Titanium Metals Corporation of America (TIMET) arrived, following Hancock Manufacturing in 1945, as the older sewer pipe, terra cotta, brick, glass, and clay industries wound down.
- 1960Population peaked at 7,780; it had fallen to 5,303 by the 2020 census.
- 2019Cryptosporidium detected in 2 of 9 raw Ohio River intake samples during source-water monitoring; not detected in finished water.
