Everett, Wash., approves $113 million pipeline project to cut sewer overflows

(UI) — Everett officials have approved $113 million in funding for new underground water, sewer and stormwater pipelines tied to a major storage facility project, as reported by The Daily Herald.

The pipelines will run along West Marine View Drive and are designed to carry excess stormwater to the Port Gardner Storage Facility, a large-scale system built to manage overflow during heavy rain events.

The storage facility, valued at more than $200 million, is intended to temporarily hold stormwater until it can be treated, helping reduce combined sewer overflows that have historically discharged untreated wastewater into the Snohomish River and Port Gardner Bay. The issue stems from older infrastructure that combines stormwater and sewage in the same pipes, creating overflow risks during peak conditions.

City officials expect the facility to hold roughly 7 million gallons of water and reduce overflow events by about 95%. Construction on the pipeline segment could begin as early as mid-2026 and is expected to continue through 2027, with work phased to limit traffic disruptions along the corridor.

The project will be funded through the city’s water and sewer utility system, which is supported by ratepayer fees rather than general tax revenue. As reported by The Daily Herald, the investment is part of a broader effort to modernize aging underground infrastructure and meet state requirements for reducing wastewater discharges.
