Community Engagement
Community engagement is essential to shaping a water system plan that reflects the needs, priorities, and values of the people it serves. By listening to community input, we can make informed decisions about investments, sustainability, and long-term reliability. Stay tuned for upcoming opportunities this summer to learn more and share your voice. In the meantime, if you have questions or feedback that you would like to share regarding the water system, please email Senior Engineer Jim Grueber PE at jgrueber@bellevuewa.gov.
