This week, crews are installing a carbon fiber lining inside Pipeline 5 in North San Diego County between Fallbrook and Escondido. The work is essential to maintain the 96-inch pipeline that delivers untreated water from Lake Skinner in southwest Riverside County to the Lower Otay Water Treatment Plant in southern San Diego County.
The work began at the end of March when Pipeline 5 was shut down for the installation of two internal steel bulkheads. The bulkheads allow the rest of the pipeline to stay in service while work is performed in an isolated section.
“Ensuring that water supplies continue to be reliable for all of the region’s 3.3 million residents and businesses is our priority,” said Jim Fisher, director of operations and maintenance at the Water Authority. “We are performing this essential repair to one of our largest pipelines to make sure that there are no interruptions in service to our member agencies.”
