Plastic pipe material is increasingly used for several applications including water, sewer, and gas. Plastic pipelines currently in service are not as old as the metallic pipelines, but there have been many seemingly premature failures warranting a comprehensive understanding of their failure mechanisms and how to keep track of them for appropriate intervention. Further, many condition assessment - specifically leakage detection - techniques that are suitable for metallic pipelines are not suitable for plastic. This presentation provides an overview of the deterioration mechanisms for plastic pipelines informed by the state-of-the-art literature. Additionally, it presents research insights into leakage detection in plastic pipelines. There have been numerous papers published on various aspects of plastic pipe degradation and leakage detection in multiple utility sectors, and this presentation synthesizes the most crucial knowledge out there for practical reference.
