Disposal of Liquids

Liquids from incoming wastewater are separated from solids at the plant. After extensive treatment the liquids are discharged to Puget Sound in accordance with strict standards specified in the the county's National Pollutant Discharge Elimination System (NPDES) permit.

Disposal of Solids

Nutrient-rich solid byproducts, known as biosolids, are refined into a dry pellet and sold as SoundGRO fertilizer to local and commercial customers. SoundGRO meets Environmental Protection Agency Class A “Exceptional Quality” biosolids standards. Some solids, including grease, are disposed of at a sanitary landfill.
