Performance Monitoring of Liners: Parameter Identification

large proportion of water and wastewater infrastructure pipelines are nearing the end of their remaining useful service life. Replacement of failing pipes can cost millions of dollars to the water utilities and invoke major disruptions to the public and nearby surroundings. Liners/coatings are used in water and wastewater pipelines to minimize the effects of pipe degradation and to strengthen the integrity of the pipes. Exploiting liner/coating technologies for fit for purpose applications is a potential avenue for extending the service life of water and wastewater pipe infrastructure whilst saving capital and operational expenditure. However, liners/coatings have limited industry standards, specifications and tools to confirm their post-installation and long-term performance. The Government of the Commonwealth of Australia had funded a Cooperative Research Centres Project (CRC-P) on 'Smart Linings for Pipe and Infrastructure'. This project focuses on establishing standards and specifications, and fit for purpose liners/coatings with smart sensing/robotic capabilities to enhance the utilization of the linings in collaboration with Water Services Association of Australia (WSAA), liner/coating manufacturers, liner/coating applicators, water utilities and researchers.
