PACE staff assisted the cities of Marysville and Everett with Total Maximum Daily Load issues associated with the discharge of wastewater to the Snohomish River estuary. This project included treatment plant upgrades, a new effluent pump station, and a 36-inch effluent transfer pipeline with 18 MGD capacity. The 25,700-foot pipeline traverses three significant tidal water crossings and four miles of narrow public streets. PACE provided PS&E for the pump station and effluent transfer pipeline.
