Westerville Water Remains in Compliance with Lead Regulations
Westerville has operated a public water supply since 1901. Today, the City Water Division runs a 7.5 million gallon a day water treatment facility serving more than 15,000 homes and businesses. The treatment plant is located at 312 W. Main Street. The plant is Ohio EPA-licensed to treat 7.5 million gallons a day and is operated 24 hours a day, 365 days a year.
The high-quality drinking water produced by Westerville consistently meets all water quality regulations. In fact, Westerville has received the Outstanding Public Water System Award from the Ohio EPA.
The treatment process is broken into many steps to produce premium quality drinking water, including coagulation using ferric chloride and settling to remove particles; softening using lime and caustic soda to remove calcium and magnesium which contribute to water hardness; disinfection using chlorine to kill harmful microorganisms; filtration using sand filters to remove fine particles; fluoridation for dental protection; corrosion control using phosphate; and taste & odor control with powdered activated carbon. The water is softened to approximately 130/mg/1 or 7.5 gpg and has a fluoride level of 1 mg/l. Additional water quality information is available by contacting the plant at (614) 901-6770.
