Drinking Water Quality

2024 City of Kirkland Water Quality Report(PDF, 2MB)

Drinking water quality is a crucial aspect of public health and well-being. It pertains to the physical, chemical, and microbiological characteristics of water as it relates to its suitability for consumption. 

The City of Kirkland is a member of the Cascade Water Alliance along with Bellevue, Issaquah, Redmond, Sammamish Plateau Water and Sewer District, and Tukwila. Cascade provides its members with safe, clean, and reliable water in a cost-effective and environmentally responsible manner.

Per the 1974 Safe Drinking Water Act and Washington State Department of Health requirements, the City of Kirkland provides an annual report(PDF, 8MB)  on the origin and quality of the water it provides. Ongoing testing in 2020 showed that Kirkland's drinking water met or exceeded all state and federal drinking water standards.

Please note that the Northshore Utility District and Woodinville Water District provide water to the Finn Hill, North Juanita, and Kingsgate neighborhoods. If you live in those areas of Kirkland, you may contact the district that serves you for a copy of their water quality report.
