The Nacimiento Water Project, often referred to as "the lifeline for many local communities," is a $176 million endeavor aimed at enhancing water availability for five communities in San Luis Obispo County, California. This ambitious project features a 45-mile water pipeline designed to channel water from Nacimiento Lake to Atascadero, Cayucos, Paso Robles, San Luis Obispo, and portions of Templeton. Completed in 2010, the pipeline has faced multiple challenges since its commissioning, including three shutdowns caused by leaks, dents, and structural problems. The most recent shutdown occurred in June, leaving all five 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 mobilized excavators and divers to dig 20 feet underground and inspect the 30-inch diameter pipeline using a video camera. Although the initial leak was patched, subsequent pressure tests revealed additional cracks, totaling at least five. Despite efforts to pinpoint the exact cause, which could be due to faulty materials, welding issues, or damage sustained during installation, the root cause remains elusive. County officials have implemented a temporary fix to maintain water flow while they pursue a long-term solution. Since July 2014, the county has spent $134,000 on emergency contracts to address these issues. While current leaks are minor and do not pose significant risks, any leaked water flows into the Paso Robles Groundwater Basin.
Promoted initially as the "largest public works project ever," intended to deliver millions of gallons of drinking water, the pipeline's repeated outages have left communities without the promised water supply. With California still grappling with severe drought conditions, this water is vital. Frank Meacham, County District Supervisor, expresses growing concerns about water security for the coming year’s potential drought. Before the June shutdown, the city utilized the pipeline to replenish wells and filter lake water into pooling systems atop the Salinas riverbed to counteract summer shortages. The inability to execute this plan this summer, coupled with a substantial drop in lake levels, has heightened worries.
This latest leak marks yet another challenge for the pipeline since its beginning. During construction, three workers tragically died in two separate incidents. In August 2010, a section of the pipeline at the Nacimiento Lake intake collapsed, resulting in an eight-month shutdown post-completion. A later shutdown occurred due to a dent and subsequent rupture near Santa Margarita. Clearly, a permanent and reliable fix is essential to avoid further disruptions.
HJ3 offers the solution. Our patented carbon fiber technology has successfully repaired thousands of feet of pipeline, often under urgent circumstances. Our systems comply with NSF 61 standards for potable water, ensuring both safety and reliability. Once installed, HJ3 systems resist corrosion and chemicals, eliminating the need for future maintenance or excavation. Installation is swift and straightforward. For example, in another California county, HJ3 was tasked with repairing a severely corroded steel drinking water pipe. Rather than replacing the section, HJ3’s Civil™ system restored the pipe in mere hours.
In Miami, HJ3’s Civil™ system repaired over 750 linear feet of corroded PCCP in just three days, saving the city $1 million compared to replacement costs. Such repairs conserve hundreds of thousands of gallons of water, reduce carbon dioxide emissions, and minimize steel and concrete usage, thus cutting landfill waste.
