Sammamish is almost entirely residential, with large lots, mature landscaping and neighborhoods like Pine Lake, Klahanie and Sahalee where nearly every home has an irrigation system. That makes lawn-sprinkler backflow testing the heart of what we do here.
We test, repair and winterize assemblies across the plateau, and file each report with your water district.

Who is your water purveyor in Sammamish?
Your purveyor is the water utility that sends your annual test notice and receives your test report. Depending on your address, Sammamish properties are commonly served by Sammamish Plateau Water or Northeast Sammamish Sewer & Water 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
Plateau winters run colder than the lowlands, so exposed irrigation assemblies here are especially prone to freeze damage. We can drain and winterize your assembly on the same visit as its annual test.
