| Black & Veatch celebrates opening of upgraded plant in Oregon The opening of the upgraded and expanded Row River Water Treatment Plant in Cottage Grove, Ore., was recently celebrated by representatives from Black & Veatch, a leading global engineering, consulting and construction company, city council members, public works employees and the general public. Upgraded to meet more stringent drinking water requirements, the facility now features advanced technology with the use of pressurized microfiltration membranes in place of the conventional granular media filtration process used at the facility since its original construction in 1992. The plant's capacity also was doubled from 2 million gallons per day (mgd) to 4 mgd to compensate for the city's decommissioning of the Layng Creek plant. To keep pace with future population growth, the reconstructed plant is expandable to 8 mgd with minimal increase to the plant's operating area. A new 8 mgd intake structure was installed on the Row River, which features an air-burst screen-cleaning system and National Marine Fisheries Service compliant fish screens. In addition, to increase stream flow and improve fish habitat, one small dam was removed, and another dam is scheduled to be removed this year. write your comments about the article :: © 2009 Construction News :: home page |
