Water
Cincinnati enjoys an almost limitless supply of high quality potable water, at rates among the lowest in the country.
Greater Cincinnati Water Works (GCWW), largest of several water works in the service area, has been a municipally-owned and operated utility since it was purchased by the City of Cincinnati in 1839.
GCWW has always taken the lead in water quality research and technology to protect public health. It has been featured nationally for it's state-of-the-art water treatment and research. To ensure the highest quality drinking water, water is tested more than 300 times a day from the source through treatment and in the distribution system.
GCWW supplies more than 48 billion gallons of water a year through 3,000 miles of water mains to about 235,000 residential and commercial accounts. GCWW's service area has grown to include the entire City of Cincinnati, most of Hamilton County, and parts of Butler and Warren Counties in Ohio. In 2003, GCWW started selling water to Boone County and Florence, Kentucky via a pipeline installed under the Ohio River.
GCWW uses the latest treatment techniques in its state-of-the-art facilities to remove harmful contaminants. Cincinnati has been recognized nationally for its excellent drinking water. GCWW has always met or exceeded all state and federal health standards for drinking water.
