Greater Cincinnati Water Works has been a municipally owned and operated utility since it was purchased by the City of Cincinnati in 1839.

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.
