Water Resource Recovery Facility Spotlight – City of Sequim Water Reclamation Facility

Sequim WRF Waterfall

The City of Sequim Reclaimed Water Facility is a pioneer in the field of resource recovery with programs for both production of Reclaimed Water and Beneficial use of Biosolids. The plant, which is located on the North Olympic Peninsula, was originally constructed in 1966 as a conventional Secondary wastewater treatment plant with an outfall into the Strait of Juan De Fuca. In 1997, the treatment plant was upgraded to produce 100% of flow to Class “A” Reclaimed Water, and the Outfall was extended 1,900 feet into the Straits of Juan de Fuca. The plant was further expanded in 2010 to have a maximum month design flow of 1.67 MGD. As currently constructed, the plant consists of mechanical fine screening, influent flow measurement, grit removal, equalization basin (for daily and storm flows), aeration basins configured to perform biological nitrogen and biochemical oxygen demand removal, and secondary clarifiers. The secondary treated effluent is then coagulated and filtered either by anthracite coal media filters or a cloth media disk filter prior to UV disinfection.
