Diversification and
Operation

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.
