Thank you for visiting King County Water District No.49's website.

We are located at 415 S.W. 153rd Street in Burien. This district provides services to more than 16,000 residential and commercial users in parts of Burien and northern Normandy Park. King County Water District No. 49 has seven employees and three commissioners govern the district.

The water this district provides is supplied from the Cedar River Watershed. The Cedar River Watershed is located in a remote, uninhabited area of the Cascade Mountains and is managed by the City of Seattle. The city also maintains large transmission pipelines which convey the water from the watershed to our area. The District’s distribution system is connected to these pipelines by four separate taps on large transmission mains.

Water District No 49 is responsible for over 59 miles of water mains and over 4,100 service connections. We are responsible for pipes and connections up to and including all water meters. Every customer is responsible for his or her service line connections from the customer's side of the water meter into, and within, the property.

In case of an emergency, like a broken pipe inside the home, all customers should know the location of the water shutoff valve inside their house. If you need the water turned off at the meter, call 206-242-8535 24 hours a day. The District will send a maintenance technician to shut off the water at the meter. Please be advised that if the meter is tampered with or broken, you will be charged a $100 tamper fee plus time, materials and permitting for the repair.


King County Water District No. 49 purchases water from Seattle Public Utilities. Seattle’s Drinking water, and subsequently Water District No. 49’s drinking water is safe from the contaminant PFAS (per- and polyfluoroalkyl substances). Seattle Public Utilities have tested for these contaminants in 2015, 2018 and will test for them in 2023. More information about Seattle Public Utilities and PFAS can be found at the link below. In addition to Seattle Public Utilities testing, Water District No. 49 has results from the latest UCMR (Unregulated Contaminant Monitoring Rule) 5 testing, which focuses on per- and polyfluoroalkyl substances (PFAS). There have been no detections so far in testing. Please reach out to our office at 206-242-8535 with any questions or concerns.
