Lynchburg WWTP CSO Reduction Improvements

This project was part of Lynchburg’s long-term control plan to address 132 overflow points within the sewer system while reducing sewage and stormwater discharge into the James River from 1 billion gallons to 69 million gallons annually. The $44 million project provides additional wet weather capacity and storage, additional screening and grit removal facilities, and disinfection to prevent overflow of excess waste. The increased wet weather storage and pumping capacity is in excess of 76 mgd.

Specific improvements included a new 4-mg wet weather storage facility, backup generator, conversion of a clarifier to a high strength wastewater storage tank, and electrical building switchgear upgrade. Headworks upgrades included new pumps, screens, grit facility and electrical room. Work also included pump, piping and electrical upgrades to the primary sludge pump station and an upgrade to the CSO isolation gate to remove waste from outfall during wet weather events.
