Set on a severe slope, the project required the design and construction of a major retaining wall to allow for safe excavation, protection to a major gas line, and upgradient roadway and railroad.

Martinsville Smith River Interceptor Rehabilitation

Martinsville and Henry County, VA

Decades-Old Sewer Upgraded

The Smith River Interceptor consists of over six miles of 36-inch and 42-inch reinforced concrete pipe (RCP) and corrugated metal pipe (CMP). The interceptor is more than 50 years old and collects all of the sewer flows from the City of Martinsville and Henry County. We completed a design for an emergency bypass pumping system—which was installed to prepare for emergency response in the event an 80 percent collapsed segment of the sewer were to fail prior to construction. Included in the design was a new 40-foot retaining wall, which was necessary before excavation could begin to replace the collapsed segment of the sewer. Following replacement of the collapsed sewer, we designed the comprehensive rehabilitation and replacement of the remaining 4.2 miles of 36-inch and 42-inch corrugated metal sections of sewer along the Smith River.
