The Nacimiento Water Project, often referred to as "the lifeline for numerous communities facing water scarcity," is a $176 million endeavor designed to enhance water availability for five towns in San Luis Obispo County, California. This ambitious project features a 45-mile-long pipeline intended to channel water from Nacimiento Lake to Atascadero, Cayucos, Paso Robles, San Luis Obispo, and portions of Templeton. Completed in 2010, the pipeline has encountered multiple shutdowns since its installation, primarily due to leaks, dents, and structural defects. The most recent shutdown happened in June, leaving these communities without water from this source throughout much of the summer.
Following observations of water seeping onto an access road near the Nacimiento River, county workers brought in excavators and divers to dig 20 feet underground and inspect the 30-inch diameter pipeline. Using a video camera, they identified the initial leak, which was subsequently patched. However, a subsequent pressure test revealed further issues, leading to the discovery of at least five additional cracks in the pipeline. Despite ongoing investigations, the exact cause of these cracks remains elusive, with potential culprits including defective construction materials, welding problems, or damage sustained during installation. County officials have implemented a temporary fix to keep the pipeline operational while they pursue a long-term solution. Since July 2014, $134,000 has been allocated for emergency contract work related to these repairs. Currently, the leaks are minor and do not pose immediate risks, with any leaked water flowing into the Paso Robles Groundwater Basin.
Despite being touted as the "biggest public works project" aimed at supplying millions of gallons of potable water, the repeated shutdowns have left these communities without the promised supplementary water supply. In light of California's persistent drought, this water is critical. County District Supervisor Frank Meacham is particularly concerned about water availability for the upcoming year, especially if the drought persists: “The worry is heading into next year and whether we’ll have sufficient water then.†Before the June shutdown, the city was using the pipeline’s water allocations to replenish wells, filtering lake water into pooling systems atop the Salinas riverbed to counteract summer shortages. Without this process this summer, coupled with a significant reduction in the lake’s water level, these concerns have grown even more pressing.
This latest leak adds to the series of setbacks since the pipeline’s launch. During construction, three workers tragically died in two separate incidents. In August 2010, a section of the pipeline at the intake site near Nacimiento Lake collapsed, resulting in an eight-month closure soon after its completion. Later, another shutdown occurred due to a dent and subsequent rupture in a segment close to Santa Margarita. Clearly, the project urgently needs a lasting and dependable resolution to prevent further disruptions.
HJ3 offers that solution. Our patented carbon fiber technology has successfully repaired thousands of feet of pipeline, frequently in urgent situations. Our systems comply with NSF 61 standards for potable water, ensuring their safety and reliability. Once applied, HJ3's systems resist corrosion and chemicals, eliminating the need for future maintenance or excavation. Installation is swift and straightforward. For instance, in another California county, HJ3 was tasked with repairing a steel drinking water pipe so corroded it had developed through-holes. Instead of replacing the entire section, HJ3's Civilâ„¢ system restored the compromised pipe in mere hours.
In Miami, HJ3's Civilâ„¢ system efficiently fixed over 750 linear feet of corroded PCCP within three days, saving the city $1 million compared to the cost of replacing the damaged pipe. Moreover, repairing pipelines rather than replacing them saves hundreds of thousands of gallons of water, cuts down on carbon dioxide emissions, and minimizes the use of steel and concrete, thereby reducing landfill waste.
