Project Purpose
A 30-inch diameter sewer main that crosses under Liberty Mill Road near Germantown Elementary School collapsed and caused a Sanitary Sewer Overflow (SSO) on August 8, 2024. WSSC Water crews quickly responded and worked with contractors to set up a bypass pumping operation to move the wastewater around the collapsed sewer main – thus stopping the SSO.
Project Status


As of January 27, 2025, all underground piping has been repaired and the bypass pump removed. Final restoration will be completed in early spring, weather permitting.
Work Remaining:
A paving contractor will return in spring 2025 to complete curb-to-curb paving.
