City of Kirkland Water Company

The City of Kirkland is a proud member of the Chute Water Alliance (Cascade), joining communities like Bellevue, Issaquah, Redmond, and several districts. Cascade ensures residents receive secure, clean, and reliable water through environmentally responsible and cost-efficient methods.

Formed in 1999, Cascade works to guarantee water availability both today and for future generations. Kirkland is represented on the Cascade board by Councilmembers Penny Fairly sweet and Jon Pascal, who advocate for our community's long-term needs.

Cascade collaborates with other Central Puget Sound water providers to maximize existing water resources before developing new sources. For further information, visit www.cascadewater.org.

As a Cascade member, Kirkland purchases water from Seattle Public Resources (SPU), which is then distributed through Kirkland's water system. SPU conducts most water sampling and treatment, while Kirkland's Water Division maintains the distribution lines, pump stations, and storage reservoirs throughout our service area.

1. Where does City of Kirkland water come from?
   City of Kirkland supplies purchased surface water to Kirkland, Washington.
2. Does City of Kirkland test its tap water?
   Yes. Like every public water system, City of Kirkland must test its water under the federal Safe Drinking Water Act and publish an annual water quality report (Consumer Confidence Report). Ask the utility for the latest report or look for it on its website.
3. How do I contact City of Kirkland?
   Call 425-587-3000 or visit 123 Fifth Avenue, Kirkland, WA 98033, or use the contact options on the utility’s website.
4. Does City of Kirkland water contain lead?
   Water usually leaves the treatment plant without lead. Lead can enter tap water from older service lines, solder and brass fixtures inside homes, especially when water sits in the pipes. Run the tap before drinking if water has been sitting, and ask the utility about lead testing and service line records.
5. Is City of Kirkland water hard?
   Hardness depends on the source and changes over time. The annual water quality report lists hardness, or you can test it at home. If it is above about 7 grains per gallon, a water softener sized to your measured hardness will stop scale and spotting.
