Cross Connections

Annual testing for all testable backflow prevention devices is required by City code. 

Customers with testable backflow prevention devices will receive notification and a blank test form from the City before the test is due. It is the customers responsibility to have the test done by a certified backflow prevention device professional and verify that a completed test form showing that the device has passed the inspection has been submitted to the Department of Utilities.  Please keep a copy of the test for your records. 

Starting January 1, 2023, persons testing and repairing backflow prevention assemblies and backflow prevention devices shall be certified by a Commonwealth of Virginia tradesman certification program (identified by the Virginia Department of Professional and Occupational Regulation [DPOR] as backflow prevention device workers.)   

Department of Utilities Cross Connection Specialists inspect commercial businesses and facilities to ensure Virginia Department of Health water quality standards are in place to protect public health.

The City requires these establishments to have a reduced pressure zone backflow preventer (RPZ) installed on the main water line. This device completely contains the water in the facility and prevents it from coming back into the public water supply through backpressure or backsiphonage. To ensure the continued function of these devices, all devices are required to be tested annually and inspected by our team at any time at our discretion. Fire sprinkler systems also require their own RPZ.

The Board for Contractors regulates individual tradesmen who engage in the trades of electrical; plumbing; heating, ventilation, and air conditioning (HVAC); gas fitting; water well construction; elevator mechanics; backflow prevention; and building energy analysis. (Although the term "certified" is used, state certification of these trades is mandatory, not optional.) Individual tradesmen may also be subject to local ordinances, laws, or other requirements imposed by other state agencies, courts, or certain localities. Questions about local ordinances, etc. should be directed to the community in which the individuals plan to engage in their trade.

Due to the environmental hazards found on lawns, irrigation systems are considered high hazards with potential to backflow into the public water distribution system. For this reason, these systems must have an approved backflow prevention assembly installed and tested annually. It is the owner's responsibility to ensure that cross connections do not exist, and that the backflow prevention device is installed and maintained.
