Backflow is the undesirable reversal of flow of the drinking water supply, which may cause contaminants or pollutants to flow back into the water system through unprotected cross connections. To find out more click here.


Backflow Preventors

If you have an underground sprinkler system, fire sprinkler system or swimming pool, federal, state and local laws require you to have a Reduced Pressure Backflow Prevention Device.

A certified inspector registered with the State of Iowa must inspect this device annually.

The City’s cross connection control program is managed by Backflow Solutions, Inc (BSI). Through the use of a web-based tracking program called BSI Online, BSI provides a more efficient and cost effective means of managing the city’s inventory of backflow prevention assemblies.

If you do not plan to use your lawn irrigation system the requirement to test your backflow preventor can be waived by filling out a Certification Not to Test Form.
