Backflow/Cross Connection Control Program

The City of Oxford’s (City) Backflow/Cross Connection Control Program helps protect the public water system from contamination through any connection whereby water from a private, auxiliary, or emergency water system may enter the public water system.

Responsibility for backflow/cross connection control lies jointly with the public water supply, the water consumer, and the regulatory agencies (Ohio Environmental Protection Agency (OEPA), Ohio Department of Health, and the Butler County Board of Health).

The OEPA requires the City, under rule 3745-95 of the Ohio Administrative Code, to implement and conduct an on-going backflow prevention and cross connection control program. The City is committed to meeting the requirements of the OEPA to assure water quality at the user’s tap, and to control potential hazards to the City’s water system posed by backflow/cross connection conditions.

All new residential and commercial construction projects are to be reviewed by City staff to determine the appropriate backflow prevention device per OAC 3745-95 and City of Oxford Ordinance No. 2373.

A list of Ohio Certified backflow installers and testers is available here. Annual tests are required to ensure proper operation of each device. Any violation of this Ordinance No. 2373 may result in the termination of the water service to the customer’s property.

For additional information, you may contact the Service Department at (513) 524-5206.

The City of Oxford has contracted with BSI Online for the submission of backflow test results.
