Seattle Public Utilities sends drinking water mailer to City customers

City of Kirkland water customers to receive notice about incident involving drinking water treatment standards

City of Kirkland water customers are asked to look for a notification from Seattle Public Utilities (SPU) regarding water testing results from December 29, 2015. The notification (PDF) will come in the mail beginning January 15, 2016 but is posted to the City of Kirkland’s website at

The notice describes that operator error caused high turbity water to reach the Tolt Water Treatment Facility filters. Turbity is a measure of how cloudy the water appears. The incident did not cause a safety or health concern and had no impact on the taste of drinking water. However, because the treatment standard was not met on this particular day, the Washington State Department of Health requires that water customers be notified.

The City of Kirkland, as a member of the Cascade Water Alliance, purchases its drinking water from SPU and delivers it through the City’s distribution system. Kirkland water customers can contact the City’s Water Division at 425-587-3900 with specific questions.
