2020 Annual Report
Diversification and
Operation
Critical repairs were made on large-diameter pipes to ensure regional water supplies remained safe and reliable. During all construction projects, efforts are made to mitigate impacts to nearby communities and the environment.
Innovative Pipeline 5 Relining Completed
Essential repairs to a section of Pipeline 5 between Fallbrook and Escondido were completed in May 2020. Crews installed 156 feet of carbon fiber liner inside the 96-inch pre-stressed concrete cylinder pipe to extend its service life. The lining material was made from layers of carbon and glass fibers combined with polymers that are engineered to efficiently and effectively improve the structural integrity of large-diameter pipelines. The asset management program uses these cutting-edge technologies to monitor and maintain the condition of important regional water infrastructure. Crews adapted quickly to implement safeguards to protect their health during the COVID-19 pandemic by limiting the number of people on-site, wearing masks, and maintaining a safe physical distance.
“The timely upgrade to this section of Pipeline 5 is part of the Water Authority’s proactive asset management program. A key element of providing safe and reliable water supplies is continually assessing our 310 miles of large-diameter pipeline and making the upgrades necessary to continue serving the region.”
