The Sanitary Sewer Lining Program involves annual asset management activities focusing on the structural lining for sanitary sewer mains.
The program is intended to extend the life of aging infrastructure. The sanitary sewers require upgrading to meet today’s standards, which will minimize long-term maintenance costs. This is achieved without any road excavation.
The wastewater collection system has traditionally been replaced or rehabilitated as part of full road reconstruction projects. While it is cost effective to do this work while the roads are being constructed, it limits repairs to only sewers within road reconstruction projects. This results in many segments of the sewer collection system in need of repair being postponed, increasing the risk of failure and increasing infiltration into the sewers.
This program aims to complete sewer rehabilitation using trenchless technologies, which decreases road restoration costs and operational costs associated with repeated maintenance activities or emergency repairs.
