A Cross Connection is a connection from the water distribution system to a point of use where an elevated risk of water contamination exists. Cross connections are required to have devices installed to protect the quality of the water in the distribution system. These devices are installed on irrigation systems, fire sprinklers or other types of water uses where water could become contaminated. Backflow devices prevent water from re-entering the water distribution system in the event of a loss of system pressure. Backflow protection devices are tools that allow system users flexibility and also help maintain safe drinking water in the distribution system.
Liberty Lake Sewer and Water District has a responsibility to ensure that all system users receive safe drinking water. To ensure the system is properly protected, the District tracks backflow devices. After a backflow device is installed, regular testing and if necessary, maintenance or repair are required to ensure proper protection of the water system. Testing must be performed by a Washington State certified Backflow Assembly Tester and must be done at least once a year. If repairs are required, they usually can be completed at the time of the initial test.
After a successful test is completed, Backflow Assembly Testers submit a test report to the District. The test reports are our method of confirming that backflow function has been maintained so the system is safe for all users.
When your device has been tested, you or your tester should send a copy of the report to us at our fax number (509) 926-7691. If you have a copy of a test report available from your last test, please fax a copy to us. If your device has been tested and you donâ€™t have a copy, call your tester and remind them to forward a copy to our fax number.
If your device has not been tested, see the link to our list of certified Backflow Assembly Testers. Please contact Larry White with any questions at (509) 922 5443, Ext.228.
