Description: The North Force Main Sewer Lining project at Fort Detrick, MD allowed for 3300 LF of existing sewer piping to be lined thereby extending the overall lifespan by 50+ years, without having to replace the line. The lining method included pulling a pvc alloy material through the existing pipe, and expanding/forming the liner to the inner walls so that the maximum flow area of the existing line is captured. The method permits pulls up to 300 LF which decreased the amount of excavations expected thus shortening the schedule, and mitigating environmental impact and labor costs.
