The state requires all test results to be on file at the District office.

Effective April 1, 2025, all backflow test reports must be submitted through our online tester portal ($5.00 fee applies). We will no longer accept emailed or faxed test reports as we transition to this new system.

Please submit your test reports via the following portal:

If you need assistance with the new submission process or have any other questions, please don’t hesitate to reach out.

The Department of Health (DOH), Office of Drinking Water, has authorized Washington Certification Services at Green River College to maintain a list of certified Backflow Assembly Testers (BAT) that may provide testing services to the public. Only certified BATs that have authorized disclosure of this information are listed. There is no implication of preference, nor does this list constitute endorsement by Cedar River Water and Sewer District (CRWSD), Green River College (GRC) or DOH.

The Hire a BAT List is believed to be accurate and is updated frequently. However, CRWSD, GRC and DOH assume no responsibility for errors in or for the use of the information provided. Persons or entities relying on any information obtained from the Hire a BAT List do so at their own risk.
