It's Time to Start Thinking Creatively about Sewer Rehabilitation

Abstract

The city of Martinsville, Virginia, has long been known for an economy built on tobacco, textiles, and furniture manufacturing. In recent years, with its legacy industries in decline, the city has strategically positioned itself for next-generation technology and manufacturing sectors. Set along the state's southern border with North Carolina, Martinsville is also known for its recreational areas, including the trout-filled Smith River, a state scenic river and popular local waterway for fishing and boating. In 2014, the city identified a partial collapse in their main sewer interceptor. The 6.2-mile line, which runs adjacent to the Smith River, is the major collector for the city's sewer system and also collects the majority of wastewater from the surrounding county. Constructed in 1963, the interceptor consists of 36-inch and 42-inch corrugated metal and reinforced concrete pipe. The line had been heavily used to serve the city's industries for decades and, after more than 50 years of use, was showing signs of both severe corrosion and significant structural defects.
