Water Line Maintenance - Backflow Prevention

All homes with fire suppression systems, wells, or other secondary water sources must have a backflow device to prevent stagnant water from flowing back into the public water system. This requirement applies to homes with:

  • Residential fire sprinklers* (built after 2010) - designed in ways that lead to stagnant water in the fire protection piping
  • Wells - stagnant untreated water source
  • Secondary water sources - stagnant untreated water source (canals, rivers, lakes, etc.)

To ensure the quality and safety of our water supply, the District conducts annual testing of every backflow device within our system. This proactive measure is vital for maintaining high-quality water and safeguarding the health of our customers.

*Homes designed and built after 2024 have fire suppression systems designed so the home does not require a backflow device or annual testing

Backflow Device


This is a quick process, and your water will need to be turned off at the meter. We anticipate the interruption to be approximately 10 minutes.

  1. The backflow tester will knock on your door before they turn the water off at the meter.
  2. If requested, or the meter shows active water usage, we will return at a more convenient time.
  3. Once, the test is complete, you should not notice any changes to your water quality or pressure.

Public service is at the heart of everything we do. We value our customers and remain diligent in customer education and communication. We encourage our customers to reach out to us with any questions or concerns, and appreciate your cooperation during these maintenance activities.
