What is backflow?
On rare occasions, water pressure is interrupted—perhaps by a water
main break, a power failure, firefighters battling a nearby blaze, or some
other disruption in water service. When there is a significant loss of
pressure, water can flow back into the public water supply system. When
water flows backward into the public water supply, it is called “backflow”.
In order to prevent this situation from occurring, Davie County has a
State Mandated Cross Connection Prevention Program, which requires
users of the public water system to install backflow prevention devices to
protect the public drinking water distribution system.
Most residential homes without in ground irrigation systems will not have
or will not have a need for a testable backflow prevention device.
