About this area's water
Did you know
- Alliance calls itself "The Carnation City," a name printed on the masthead of its annual water quality report.
- Walborn and Deer Creek reservoirs together hold about 2.85 billion gallons of raw water — roughly a year and a half of supply for a 10-MGD plant running flat out.
- The plant uses ultraviolet advanced oxidation, an unusually advanced step for a city of 22,000.
- The Mahoning River backup intake has not been used since 1999, but Alliance still keeps the pumps fully operational in case it is ever needed.
- When Stark Parks lowers Deer Creek Reservoir for park construction, manganese in the raw water goes up — the city posts a public notice about it rather than letting residents guess at the discolored water.
