Lynchburg Wet-Weather Storage and Overflow Reduction
Combined sewer overflow reduction
Lynchburg added wet-weather storage and expanded its ability to pump and treat storm flows. The project was part of the city’s plan to reduce combined sewer overflows into the James River. [1] [3]
- New wet-weather storage volume [3]
- 4M gallons
- Broader improvements, as reported by PC [3]
- $44M
- Wet-weather pumping capacity [4]
- 76M gal/day
- Residents served by regional plant · 2022 [7]
- 66,508
Why it happened
In parts of Lynchburg, wastewater and stormwater share the same sewer. Heavy rain can bring more water into those pipes than the system can carry or treat at once. Storage gives the plant a buffer for peak flows. [1] [3]
What was built
The 2021 improvement project added a four-million-gallon precast, post-tensioned tank, upgraded screening and grit removal, increased pumping capacity, and converted a clarifier for high-strength wastewater storage. [3] [5]
What changed
The plant gained more capacity to hold, pump, screen, and disinfect flows during storms. This work was one stage in Lynchburg’s long-term overflow control program. The city’s later Blackwater tunnel is a separate project. [3] [2]
