Row River Water Treatment Plant
City of Cottage Grove, Oregon
West Yost performed design services, is currently providing bid support services, and will be providing construction support services to the City of Cottage Grove for the Row River Water Treatment Plant Expansion Project. The project’s objective was to expand the water treatment plant’s capacity from 4 mgd to 6 mgd. The design included hydraulic evaluation of the feed and finished water pump stations, evaluation of the existing membrane filtration system, addition of a membrane filtration treatment train, and upgrades to the electrical and control systems to support the expanded facilities. The team worked closely with the City staff and the membrane system supplier to identify operational and maintenance issues experienced with the existing membrane filtration system and to incorporate improvements to address these issues in the design.
