An aging sanitary sewer system required replacement across Peachtree Industrial Blvd in Duluth, GA. The 14 inch diameter gravity sewer had to be installed via a trenchless method across the busy highway. A 38 foot deep excavation was installed between Peachtree Ind Blvd and a residential apartment complex. A combination of sheet piling and slide rail systems were utilized to safely excavate the deep pit.
