Bellevue sewer capital investment projects ensure that current and future generations have reliable wastewater services. They also help protect the natural environment that we value in the Pacific Northwest. These projects are proposed in the 2021-2027 Utilities Capital Investment Project (CIP) plan, subject to approval by the City Council in November or December 2020.
