This project obtained condition assessment information for approximately 47,000 feet of 18 to 42-inch diameter sanitary sewer pipes and 197 manholes located near Herndon, McLean, and Annandale. The inspections were performed using multi-sensor (Closed Circuit Television (CCTV), sonar, and laser) inspection technologies to identify internal defects. Defective sewers were identified for repair, replacement, or rehabilitation under future contracts. This project was substantially complete on January 15, 2021.
