Drainage & Sewer Plans

A current Seattle Public Utilities (SPU) planning project is called "Shape Our Water." It is a community-centered project about the next 50 years of resilient drainage and wastewater systems.

As we face powerful forces like climate change and rapid growth, future investments in water systems will transform our city. Learn more about how we can work together at our Shape Our Water website and in our Drainage and Wastewater 50-Year Plan fact sheet.

SPU is also currently implementing the following drainage and sewer system plans that will guide our work into the future.
