Stantec assisting Washington city on water pollution control facility

As the City of Everett, Washington, continues to grow, the city’s Public Works Department is developing a facilities plan for its Water Pollution Control Facility (WPCF). Stantec is currently providing an alternatives analysis for the 60-year-old facility with the goal of guiding capital and operational investments for the next two to three decades.

The facilities plan will assess overall facility condition, future service demands and resiliency and redundancy considerations, while developing a strategy or “playbook” to comply with pending long-term regulatory changes. The regulatory changes will likely impact wastewater treatment plant discharges into Puget Sound as mandated by the Washington State Department of Ecology.

The plan also will provide suggestions to improve resiliency to natural disasters and the changing natural environment, identify opportunities to enhance the community with valuable resources produced at the facility, and provide a list of improvements that support economic development while minimizing impacts to existing ratepayers.

“We’re excited to help the City of Everett shape its investment priorities in critical infrastructure,” said Dave Price, Stantec senior principal and project manager based in Bellevue, Washington. “Our goal is to help the City develop a plan for facility upgrades that will affordably produce higher quality effluent. This will be a resilient facility that the City and community can rely on for decades.”

“Everett is committed to preserving the health of Puget Sound in a cost-effective manner. As we look to the future of our community, the proactive development of the facilities plan for the Water Pollution Control Facility will help provide for the sustainable, resilient, and reliable treatment of wastewater,” said Jim Miller, Everett’s city engineer. “This is an essential plan that can help our community prepare for the next several decades of treatment plant upgrades.”

The Everett WPCF serves nearly 170,000 people, providing full secondary treatment of 40 million gallons per day, with peak flows of up to 96 million gallons per day. The service area serves two distinct systems, a combined sewer system on the north end of the city and a separated system in the south. The southern portion of the service area receives flow from neighboring residential and commercial areas.
