Combined Sewer Overflow (CSO) Reduction

Spokane, Washington

Century West worked with the City of Spokane and other consultants to develop a CSO plan which would address CSO reduction and compliance with State and Federal regulations as they pertain to CSO discharge to the Spokane River and its tributaries. Century West provided basin plan design, regulatory interpretation, and program management. This multi-million dollar project was designed to protect the water quality of Spokane’s river and aquifer that sustain a vibrant future for the Spokane community. This project is multi-disciplinary in nature and includes innovative approaches to sewer design and modeling, water quality analysis, historical and regulatory research, and constant interaction with the public and regulatory agencies.
