Wastewater Services

The wastewater (sewage) from your home, school or business is piped by gravity for the wastewater treatment plant on Sandy Boulevard. More than 13 million gallons of wastewater are treated each day. The facility is open to the public for organized and self-guided tours.

Wastewater Services provides reliable wastewater service to citizens and businesses by operating and maintaining the wastewater collection and treatment facilities. Residential wastewater customers pay less than a dollar per day for a home. 



The City's wastewater treatment plant is the first in the Pacific Northwest and one of only a handful in the nation to reach energy net zero status.
