Bitter Lake Reservoir Improvement Project

East view of preliminary new reservoir design

Project description

Seattle Public Utilities (SPU) is building a new drinking water reservoir in the Bitter Lake neighborhood. The new 21-million-gallon Bitter Lake Reservoir will replace the existing reservoir that is reaching the end of its service life. The new reservoir will be partially buried and hold the same amount of water as the old reservoir. More open space will be available for the community to enjoy after the project is complete. Seattle Parks and Recreation plans to turn the additional open space into a park. Park construction will occur after the new reservoir is built.

Location

The reservoir is located on a 13-acre property located southwest of the intersection of Linden Ave N and N 143rd St in North Seattle. About four acres is currently open space, a playground, and a community garden.

What's happening now?

The project has reached the 30% design milestone and is collecting feedback from the community now through June 12.

See the design plans and share your feedback at our online open house.

We’ll be in the neighborhood if you want to talk to us and share your thoughts about the design plans. We hope to see you!

Community benefits

This project is part of SPU’s regional drinking water system. When construction is complete, the new reservoir will provide protection from sunlight, dirt, leaves, and other debris to help preserve water service and quality for years to come. The project will provide additional open space for the community.

SPU is committed to providing timely information and updates on project activities. Updates may be available in multiple formats: the website, emails, mailings, drop-in sessions, briefings, and public meetings.
