The Chambers Creek Regional Wastewater Treatment Plant (WWTP) uses a combination of physical and biological treatment processes to treat residential and commercial wastewater generated within the designated service area. This service area includes the Cities of Lakewood, University Place, and Dupont, the Town of Steilacoom, and the unincorporated areas of Pierce County in Midland, Parkland, Spanaway, South Hill and the Frederickson Industrial area.

The highly treated wastewater is discharged in accordance with strict standards set forth in the the County's National Pollutant Discharge Elimination System (NPDES) permit issued by the Washington State Department of Ecology. Residual solids from the treatment process are converted into a nutrient-rich material known as biosolids is further refined into a dry pelletized fertilizer classified as an 'Exceptional Quality' Class A product. This fertilizer, also known as SoundGRO, may be used in residential or commercial applications anywhere conventional chemical based fertilizers are used.

A highly trained staff of plant operators, mechanics, electricians, instrumentation technicians, laboratory analysts, pretreatment program inspectors, construction management, office, and supervisory personnel and field crews operate the facility and inspect and maintain the sewer system infrastructure that conveys wastewater from the sewer service area to the treatment plant.
