Backflow Requirements for Commercial Customers

All new commercial customers are required to install a Reduced Pressure Backflow Assembly (RPBA) on their domestic and/or irrigation water service. For a fire service, a Double Check Detector Assembly (DCDA) must be installed. If a fire system contains anti-freeze compounds or any other chemicals, then a Reduced Pressure Detector Assembly (RPDA) is required. Other metering options are available for fire services. Please call (541) 726-2396 for more information.

In commercial or industrial situations, water often comes in contact with different types of hazardous substances, whether it be for mixing, diluting, flushing, or cleaning. State law requires that certain businesses be surveyed for potential cross-connections and that proper backflow assembly be installed to protect the public water supply. SUB Water Division surveys manufacturing plants, hospitals, mortuaries, dental offices, dialysis centers, veterinary clinics, doctors’ offices and many other businesses in order to identify potential hazards to the water system.

We evaluate backflow requirements for businesses on an individual basis when a water account is established. Businesses that have a potential backflow hazard present must install the appropriate backflow prevention assembly and have it tested annually.

If a backflow assembly is already installed
If your commercial property already has a backflow preventer assembly, you’re responsible for having it tested annually by a third-party Backflow Tester from our Certified Backflow Tester List. We will notify you by mail when it’s time for your backflow assembly to be tested.

Please provide a copy of the reminder letter to your Backflow Tester. The letter will give the Tester the information needed to submit the test results to Springfield Utility Board (SUB) Water Division.

If you are required to install a backflow assembly
We will notify you by mail if a backflow preventer must be installed. The letter will include instructions on which type of backflow preventer to install and installation guidelines. Follow these steps:
1. Obtain a permit. Contact the City of Springfield for a permit application at (541) 726-3753.
2. Learn about protecting water quality and your plumbing system. Read the Customer Stewards in Preventing Cross-Connections. Also, the installation of a backflow assembly may alter the customer system operating pressure, flow, and/or influence other hydraulic functions. Additional plumbing adjustments may be required to prevent thermal expansion damage. Please refer to the Thermal Expansion Brochure.
3. Install the backflow preventer. Be sure to install it according to our installation guidelines. We recommend hiring a professional installer. Provide the installer with a copy of the letter and accompanying information. SUB is not responsible for plumbing corrections or delays in obtaining or continuing water service due to backflow assembly installations that do not meet SUB Water Division Cross-Connection Control Program Full Manual standards.
4. Inspection. Once the backflow assembly is installed, contact SUB Water Division at (541) 726-2396 and the City’s 24-hour building inspection request line at (541) 726-3769 to schedule an inspection.
5. Test upon Installation. Contact a third-party Backflow Tester from our Certified Backflow Tester List to test the backflow assembly. The tester will submit the results to us. Also available is the Water Division’s Certified Backflow Assembly Tester Code of Conduct.
6. Annual Test. The backflow assembly must be tested annually by a third-party Backflow Tester from our Certified Backflow Tester List. We’ll notify you by mail when it’s time for your annual test.
