The Warren Community Water and Sewer Association, Inc. was organized and incorporated in 1969. It was funded by the United States Department of Agriculture, Farmers Home Administration, with a combination of grants and loans. Construction of the system was begun in 1975, with water service started in 1976. There were 628 taps paid at the time of the loan closing. Water was initially provided by the Little Hocking Water and Sewer Association.
In 1979 Union Carbide Metals joined the system. Their water demand was such that the system was divided, with the southeastern part now supplied by water from the City of Marietta Water Department. Due to increasing water cost, the Association began to search for a suitable water source for development.
In 1992 the current well field located in Oak Grove was put in service, providing water to all Warren Community Water customers from a new 750,000 gallon tank located on State Route 676 near the Washington County Career Center. The well field initially had two production wells which supply water at approximately 730 gallons per minute. Also in 1992 the Highland Ridge Water and Sewer Association agreed to purchase water from Warren Community Water, installing a meter station at the well field and running a line across the Muskingum River to serve the new system.
In 2002 a new tank was put in service on Bramblewood Heights. This 750,000 gallon elevated storage tank replaced a 40,000 gallon ground level tank above Trestle Hills Road, vastly improving the reliability of service to the industrial area along State Route 7.
In 2004 a third well was put in service at the well field. Two 200,000 gallon storage tanks were constructed, and the well field was restructured to allow pumping of two wells at the same time, thus bringing the daily production capacity to over 2 million gallons per day.
In 2010 fluoride was added to the system in accordance with Ohio EPA requirements, and a source water protection plan was approved to aid in protecting the well field. The system currently serves approximately 2300 taps.
