The City of Oak Harbor is modernizing its existing wastewater system to improve aging infrastructure, serve the community, and better protect Puget Sound – specifically the waters of Oak and Crescent Harbors. The City’s current wastewater treatment system, which consists of two facilities, is aging, difficult to maintain, nearing capacity, and not equipped to meet future water quality standards. To meet Washington State Department of Ecology regulations, the City is upgrading the wastewater treatment system.

The City is building a new wastewater treatment facility that will:

  • Deliver long-term reliable service to the communities we serve in Oak Harbor
  • Reclaim valuable resources from wastewater
  • Support the City’s future growth
  • Enhance public spaces
  • Serve as an important element for other projects that will help to revive the downtown waterfront in Oak Harbor
