District Projects ----

King County Water District No.49 is committed to maintaining and improving the infrastructure that provides clean fresh water to more than 16,000 residential and commercial users.

Proposed Water Reservoir and Booster Pump Station

The District is planning to construct an above-ground water reservoir and booster pump station on District property between 8th Ave SW and 9th Ave SW on the south side of SW 146th St in Burien. Additional storage is required to support higher fire flow demands and to make the local water supply system more reliable under high demand or emergency supply conditions. A Public Information Meeting was held on April 18, 2108. A copy of the presentation, including preliminary site plan and structure drawings, can be found here. The project is in the early stage of design and permitting. The District invites your input and feedback – please contact us by phone, email or mail. You can use the form found here or reach us through our Contact Us page. The general schedule is for design and permitting to continue into early 2019 with construction planned for later in 2019 through 2020.
