Water plant retrofit eliminates dwindling capacity
This article discusses a case study of the City of Danville, Virginia, where the water utility recently undertook a $3.3 million retrofit of its municipal water plant to replace worn‐out equipment and to restore the 18‐mgd (68‐ML/D) capacity that the state permits the utility to draw from the Dan River. The article describes the process of developing a master plan to prioritize the improvements, in particular the aging pumps and filters needed to be replaced. A second supervisory control and data acquisition (SCADA) system was installed to control the raw water pumps, plant treatment process, filter efficiency, and process control. The existing SCADA system monitors and controls the nine booster pumps and eleven finished water storage tanks in the distribution system. Also, two high‐service pumps were replaced, one is a diesel‐powered unit that can deliver varied flow rates and the other is equipped with a variable‐frequency drive for additional flexibility.
