What is Backflow?

Cities' water distribution system are designed to keep water flowing from the distribution system to you the customer.  However, when hydraulic conditions deviate from normal flow conditions, water flow can be reversed or backflow.  When this backflow occurs, water can flow from the customer’s system back into the City’s distribution system.

Who Is Required To Test and How Often?

Backflow prevention assemblies are to be tested annually or more often if requested by the Environmental Division.  The Cross Connection Program applies to and is primarily enforced on commercial businesses.  However, circumstances may apply that would require these devices to be installed on non-commercial properties.  It is recommended that when installed on residential properties that these devices be tested annually by a Certified Tester to ensure equipment performance.
