Station/Tunnel Leak Rehabilitation ($46 Million)
Water, moisture and humidity cause premature deterioration of Metro’s infra- structure, track components, electrical, lighting and automatic train control equipment. Station/Tunnel Leak Mitigation work eliminates unsafe wet condi- tions for Metrorail passengers and prevents service delays resulting from water intrusion.The goal of this capital project is to maintain the structural integrity of the tunnel liners and prevent the corrosion of wayside systems and equipment. Repairing station/tunnel leaks over the next ten years requires $46.0 million to conduct engineering assessments, purchase specialized access equipment and provide additional training for employees.
