FAQs

Cross Connection Backflow

• How much is this going to cost?

  Testing is not completed by The City of Woodland. Depending on the contractor that you select, costs will vary.  Please contact a tester to find out what their fees are.

• What if I opt to not complete the testing?

  If you choose not to complete the required annual testing, the City of Woodland can opt to terminate the connection between the city water supply and the facility or residence. If the connection is terminated, the city will charge a reconnection fee for subsequent connection.

• What is a backflow assembly?

  A backflow assembly is a component for your sprinkler system or other hazardous connection that keeps the dirty water in that system from flowing backwards into your plumbing and the public drinking water.

• Why does my backflow assembly have to be tested every year?

  Your backflow assembly is a mechanical device with moving parts that can break just like your car can break down. The State of Washington has determined that annual testing is most appropriate as stated in WAC 246-290.

• Why is it my responsibility?

  Your backflow assembly’s installation and maintenance, which includes annual testing, is your responsibility because it is protecting the public water supply from your sprinkler system or other hazardous connection. If not for your sprinkler system or other hazardous connection, there would be no need for the backflow assembly.
