Bothell straddles two counties, and its backflow needs are just as varied: newer townhome communities in North Creek, established neighborhoods like Maywood and Westhill, and the Canyon Park business park, where labs, manufacturers and medical offices depend on reduced-pressure assemblies.
Wherever your property sits, we'll test the assembly, file the report with the right purveyor and keep you ahead of next year's due date.
Backflow services in Bothell
Who is your water purveyor in Bothell?
Your purveyor is the water utility that sends your annual test notice and receives your test report. Depending on your address, Bothell properties are commonly served by the City of Bothell, Alderwood Water & Wastewater District or Northshore Utility District.
Not sure which one is yours? Check the top of your water bill or the test notice itself. Or just give us your address when you book and we'll figure it out and send your report to the right place.
Local know-how
Canyon Park's labs, biotech and light manufacturing are classic high-hazard cross-connections. They almost always require a reduced pressure backflow assembly, and many buildings have several. We schedule testing around your operations so you're not losing water during production hours.

Bothell backflow FAQs
Which purveyor gets my Bothell backflow test report?
It depends on your address. Parts of Bothell are served by the City of Bothell, while other areas are served by Alderwood Water & Wastewater District or Northshore Utility District. We'll confirm yours and file with the right one.
Can you test without shutting down water to our Canyon Park facility?
Talk to us about it. A single assembly usually takes well under an hour to test, and if your building has parallel assemblies we can test one while the other keeps water flowing. We can also plan around shift changes.
