Whole-home carbon filtration, softening and RO drinking water for Kirkland homes, installed starting at $3,500. Transparent, all-in pricing quoted before any work starts.
City of Kirkland water comes from Seattle Public Utilities through the Cascade Water Alliance, and it usually comes from the South Fork Tolt River watershed. Cedar River water is added only in rare summers with high demand and little rain; in 2024 Kirkland received none. Tolt water is filtered and ozonated, then disinfected with chlorine, which averaged 0.97 parts per million in 2024.
The city water system covers Kirkland from parts of the South Juanita and Totem Lake neighborhoods southward. Homes in Finn Hill, Kingsgate and North Juanita are served by Northshore Utility District and Woodinville Water District, which publish their own reports, so the address matters here. On the city system, Tolt water measured 1.43 grains per gallon of hardness, which is soft water.
Most of this region's water is soft, so the first thing Kirkland homeowners tend to notice is taste: chlorine at the kitchen tap, or water that just does not taste the way they want it to. Where a city draws on wells, what comes out of the tap can differ from the mountain supply next door.
Whatever your situation, the next step is the same: we pull the public data on your water, tell you exactly what your home needs, and install it for one all-in price.
Every Kirkland job is handled locally, start to finish, by a Puget Sound company.
