The Henry H. Lanum Jr. Water Filtration Plant, located on Route 130 in Amherst County, was built in 1955. The plant was expanded in 1977 to increase the capacity to 2.0 million gallons per day (MGD).
In 2006, Amherst County Service Authority (ACSA) began a process to address ongoing changes in the regulatory landscape and the need for modernization. As a result, the project team of Hurt & Proffitt, Arcadis U.S. Inc., and Kincaid-Bryant prepared construction documents for a technological upgrade that will address new regulatory requirements, replace and repair aging equipment and structures, and prepare the plant for a future production capacity of 4.0 MGD. Improvements to the facility include a new clearwell, control room, chlorine room and loading dock.
In the fall of 2009, ACSA entered into a $6 million contract with English Construction Company, Inc. to complete the technological plant upgrades over an 18 month period. Limited open space and the need to keep the facility in operation will require continued H&P coordination of communications between the County, design team, and the contractor.
