Waste Water Treatment
The Lynnwood Wastewater Treatment Plant (WWTP) is located along the shore of Browns Bay on the Puget Sound. The WWTP treats approximately 5 MGD (million gallons per day) of sanitary sewage in accordance with Washington State Department of Ecology (DOE) and Federal EPA regulations. The clean treated effluent is discharged into Puget Sound while the removed solids are incinerated in a fluidized bed incinerator.
The Lynnwood WWTP is staffed 24 hours per day, 356 days per year with treatment plant operators, laboratory technicians, and maintenance personnel.
Sanitary sewage is transported to the WWTP via 104 miles of sewer mains and six lift stations located throughout the City of Lynnwood. The lift stations and the wastewater treatment plant are equipped with emergency generators that keep the sewage treatment system running even in the event of a power outage.
