Des Moines is a waterfront city first: the marina, the beach park and the restaurants along Marine View Drive sit beside neighborhoods like Redondo, Zenith and Woodmont, where homes climb the hillside above Puget Sound. We test the irrigation, domestic and commercial assemblies that come with all of it.
From the Marina District to Pacific Ridge along Highway 99, we test, repair and file reports with your water district.
Backflow services in Des Moines
Who is your water purveyor in Des Moines?
Your purveyor is the water utility that sends your annual test notice and receives your test report. Depending on your address, Des Moines properties are commonly served by Highline Water District or Lakehaven Water & Sewer 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
Marinas and boat moorage run water out to the docks, where a hose left in the water or a pressure drop can create a real backflow risk. Dock supply lines are generally treated as high-hazard connections and protected accordingly.
