Protect Your Water by Installing Backflow
Prevention Equipment
When water reaches your home, it's important to
prevent contamination from a cross-connection. A
cross-connection is any actual or potential
connection between the public water supply and a
source of contamination or pollution.
Lawn irrigation systems are considered a high
cross-connection hazard and they must be equipped
with an approved and properly installed backflow
prevention assembly. Irrigation systems that are not
protected could endanger your health and that of
your family and neighbors.
The Iowa Department of Natural Resources (DNR)
requires that backflow assemblies be tested when installed
and annually thereafter to ensure proper operation.
The testing must be done by a company that has a
registered backflow prevention assembly tester and
the test results must be sent to CFU.
