WCSA Water Treatment Plant and Distribution System

CHA provided planning, permitting, design, bidding, and construction phase services to the Washington County Service Authority (WCSA) for the upgrade of its Middle Fork Water Treatment Plant (WTP) to 12 MGD. This was accomplished in two construction projects. The first project expanded the WTP from 4.6 to 6.6 MGD to save the WCSA approximately $1,000,000 annually in water purchases and was designed and constructed in less than 20 months. The second construction project expanded the WTP from 6.6 to 12 MGD to provide reliable drinking water for the 30-year planning period.

The interim expansion and the final expansion to 12 MGD for the water treatment plant included pre-sedimentation with tube settlers in the existing sedimentation basins, high-rate sedimentation utilizing three adsorption clarifiers the retrofit of three existing dual media filters, the construction of five new dual media filters, and 600 horsepower finished water pumps. Additional improvements included the baffling of the existing clearwell, a chemical storage and feed complex, new flocculation tanks, and an energy recovery turbine to save the WCSA approximately $30,000 annually in power costs.
