All backflow prevention devices installed on city potable drinking water service lines and functioning as secondary containment are required to be tested annually. The city will send email notices prior to assembly due dates. Backflow prevention devices installed on reclaimed water services are exempt from this requirement. 

Backflow Program Annual Tester Notification and Discontinuation of Water Service Standard Operating Procedure

  1. First notice letters are issued sixty (60) days before the certified backflow test is due and water services may be shut off. (The notice specifies a 60-day response period)
  2. If passing test reports are not received within thirty (30) days of the first notice, a reminder notice is sent before water services may be shut off. (The notice specifies a 30-day response period)
  3. If the passing test reports are not received at least five days (5) prior to the due date, a final reminder notice is issued before water services may be shut off. (The notice specifies a 5-day response period)
  4. If passing test reports are not received by the compliance date, water service will be shut off on the following working day.
  5. Water service will remain shut off until a passing certified backflow test is received or completed under the supervision of a Water Quality representative from the city. A copy of the passing certification must be provided at this time.
