Eugene Water & Electric Board (EWEB): backflow testing rules

Who must test

• The state of Oregon and EWEB require the installation and annual testing of all backflow prevention assemblies. Source.
• Common residential uses needing backflow protection include residential fire suppression, all irrigation systems, hydronic and geothermal heating, pools and hot tubs, water features, pumps, and buildings over 3 stories. Source.

Notices and deadlines

• Customers may receive an annual testing reminder letter. Residential customers can enroll in the Good as Gold Program and designate a yearly tester, so reminders go to the tester and the assembly is placed in the tester's work queue each year. Source.

How the report is filed

• New assemblies must be tested on installation by a State of Oregon certified backflow assembly tester, who must submit results to EWEB within 10 days of the test. Source.

Tester registration

• EWEB posts a Backflow Database Agreement and Addendum for use by backflow testers only (linked file is titled Online Backflow Database Use Agreement), indicating testers enter results in an EWEB online database. Source.

Fees

• Commercial customers can sign up for EWEB-facilitated testing; a state-certified contractor is assigned and the testing fee is added to the EWEB bill after results are received. Residential Good as Gold customers pay the tester directly. No dollar amount is stated. Source.

Approved testers

• EWEB links a Backflow Tester List PDF of state-certified testing contractors. Format PDF. Not downloaded. Source.

If a test is missed

• A failed assembly must be repaired as soon as possible and not more than 10 days after the failed test. Source.

Program

• EWEB's backflow prevention page explains cross-connections and states that any backflow prevention assembly must be tested every year. Source.
