Implemented in 2011, the purpose of the Backflow Prevention and Cross-Connection Control Program is to protect the City's drinking water supply from a backflow event and to continue delivering safe and reliable drinking water to Virginia Beach residents.

Accordingly, this program was created and is administered by Public Utilities as outlined in the cross-connection control and backflow prevention policy and Virginia Beach City Code 37-68, in conjunction with the Virginia Department of Health (VDH) and the Environmental Protection Agency (EPA).​

Per the Virginia Administrative Code 12VAC5-590-630, anyone testing and repairing backflow prevention devices must be certified by a Commonwealth of Virginia tradesman certification program (identified by the Virginia Department of Professional and Occupational Regulation as a Backflow Prevention Device Worker).
