2. The customer shall immediately notify the City water utility when the customer becomes aware that backflow has occurred in the building, property or private water system receiving water service, and take measures to confine the contamination or pollution by turning off valves to isolate the area of the incident. The City may order that a water service be temporarily shut off when a backflow occurs in a customer’s building, property or private water system.

Backflow prevention assemblies shall be installed by a licensed plumbing contractor per established plumbing codes. A licensed backflow prevention testing technician, registered with the Iowa Department of Public Health, shall test the backflow prevention assembly at initial installation and annually each year thereafter. Backflow prevention assemblies installed on irrigation systems shall be tested annually by May 31 of each year. Backflow prevention assemblies must be retested when repairs have been completed to ensure the repaired device is operational.
(Ord. 1808 – July 14 Supp.)
