Lynchburg WWTP Upgrades

Lynchburg, Virginia

MEC was construction manager at risk (CMAR) for this project to upgrade a combined sewer overflow (CSO) system. During periods of heavy rain, the combined volume of the storm and wastewater exceeded the collection pipe’s capacity, forcing sewage into the James River. To solve this, the client constructed a new, $44.5 million facility including a 4-million-gallon wet weather storage facility and backup generator, and a new electrical building with replacement transformers, switchgear and motor control centers. Upgrades to the headworks building included new pumps, screens, grit facility and electrical room.

The new plant was built within the original plant’s footprint, while the old facility remained in service for the duration of the project.

Commissioning of all electrical equipment and refeed of loads in the headworks building took place within a scheduled 6-month outage concurrent with construction of a new non-potable water electrical building, primary pump station, and wet weather chemical building and storage tank.
