Crews install a carbon fiber liner in Pipeline 4 in October 2019 to give the pipeline several more years of service while a longer-term solution is developed and deployed.

Pipeline 4 Repairs Completed In North San Diego County

/in , /by

Pipeline 4 – one of the San Diego region’s major water pipelines – is back in regular service after a leak was repaired, a testament to the San Diego County Water Authority’s proactive asset management program.

The pipeline resumed normal operations November 10 after nearly two months of modified operation. The leaky section was near Camino Del Rey in Bonsall, in an area with no adjacent homes or businesses.

“The shutdown and repair work went smoothly, and we could not have done it without the support and coordination from Water Authority staff, our contractors and member agencies, particularly, Fallbrook PUD, Rainbow MWD, Valley Center MWD, and Vallecitos Water District,” said Neena Kuzmich, Water Authority engineering manager.

Carbon fiber section will protect Pipeline 4

Water Authority crews detected a leak in the 90-inch diameter Pipeline 4 in the Moosa Canyon area in August.

Crews installed bulkheads in the pipeline to isolate the leak area for repairs. The bulkheads allowed the pipeline to continue treated water deliveries throughout the county in a modified fashion and restored full service to retail water agencies.

The Water Authority installed a carbon fiber liner to give the pipeline several more years of service, while a longer-term solution is developed and implemented.

Once the repairs were completed, a second shutdown was needed to remove the bulkheads and return the pipeline to full, normal operations.

Pipeline 4 is one of five major pipelines operated by the Water Authority.

Proactive approach keeps pipelines healthy

By relining the pipes and conducting timely repairs with the latest technology, the Water Authority has avoided major pipeline failures for more than decade.

Extending the life and reliability of major pipelines is one facet of the agency’s proactive asset management program. Real-time monitoring and other pipeline assessment tools help the Water Authority avoid pipeline failures by identifying potential problems in advance.

As part of its proactive approach, the Water Authority continually assesses and rehabilitates pipelines serving the San Diego region. The agency operates 310 miles of large-diameter pipelines, along with 1,600 aqueduct-related structures, and approximately 100 metering/flow-control facilities.

Approximately 82 miles of the pipelines are pre-stressed concrete cylinder pipes. These types of pipes were installed between the early 1960s and late 1980s and have experienced premature failures and shown areas of degradation.

In the past few years, the Water Authority has continued to extend the service life of pipelines with relining projects, including Pipeline 3 between Lake Murray and Sweetwater Reservoir, and Pipeline 5, in the Fallbrook area.

Vallecitos Water District ‘Work We Do’ Videos Connect With Community

/in , /by

The Vallecitos Water District is moving beyond traditional bill mailers and tri-fold brochures to communicate with its customers in a more effective and dynamic way by using video.

Vallecitos Board President Hal Martin conceived the idea to create “Work We Do” videos to help customers see and understand first hand the complex work Vallecitos water professionals perform to ensure reliable water and wastewater services. Viewers see and hear from the workers in the field as they complete tasks such as replacing outdated equipment or using smoke testing to detect sewer leaks and protect the environment.

“I’ve seen the quality of staff videos and I realized it was the perfect way to show our customers exactly what we do,” said Martin of the series and the initiative.

Watching crews in action providing the community with reliable drinking water and wastewater services, protecting the environment, and developing the next generation of water workers, makes customers better informed citizens about the area’s vital infrastructure in a transparent way.

The video series also includes helpful information such as how to read water meters.

“We’re working to change our Public Information Department and keep up with current technology,” said Chris Robbins, Vallecitos public information and conservation supervisor.

Robbins said the goal is to feature each department within the district and focus on topics that lend themselves to visual communication. Videos run three minutes or less to keep the audience engaged.

Finished videos are posted to the district website, YouTube, Facebook and Twitter. The videos can also be seen on the City of San Marcos news channel, San Marcos TV. Videos are also shared through water industry news websites such as Water News Network.

Alicia Yerman, a Vallecitos public information representative, shoots and edits the video series. She schedules time to join crews at work when performing a specific task. She also plays talent scout, finding a knowledgeable employee who can describe the work on camera.

Not all staff want to talk, but Yerman is able to coax at least one Vallecitos staff member to be the ‘on camera talent,’ and she also has a knack for bringing out their best. She finds ways to make staff more comfortable being on camera—either by asking questions or placing staff members in comfortable settings.

Yerman and Public Information Representative Lisa Urabe were recently certified as drone pilots. Future videos will feature district work from a bird’s eye point of view.

City of Oceanside Invited to Apply for Water Infrastructure Loans

/in , /by

The City of Oceanside was invited by the U.S. Environmental Protection Agency (EPA) to apply for two separate Water Infrastructure Finance and Innovation Act (WIFIA) loans. Oceanside submitted letters of interest in early summer 2019 for the Pure Water Oceanside and Lower Recycled Water Distribution System Expansion Project as well as the Buccaneer Sewer Lift Station and Force Main Project. Oceanside’s letters of interest were among 51 others received by the EPA from both public and private entities in response to its 2019 WIFIA Notice of Funding Availability. After a robust review process, the WIFIA Selection Committee chose 38 prospective borrowers’ projects to submit applications for loans, including both projects submitted by the City of Oceanside.

Pipeline 4 Repairs Underway in North San Diego County

/in , /by

A recently discovered leak in a section of a pipeline in North County will be repaired in coming months while Pipeline 4 returns to service.

Crews have installed bulkheads in the pipeline to isolate a portion of Pipeline 4 for repairs. This will allow the pipeline to continue treated water deliveries throughout the county in a modified fashion starting the week of Sept. 16 and restores full service to retail water agencies. With the leaky section isolated, crews will make necessary repairs.

Four Water Authority member agencies – Fallbrook PUD, Rainbow MWD, Valley Center MWD, and Vallecitos Water District – have taken steps to manage water supplies while the pipeline was shut down to install the bulkheads.

Carbon fiber section will protect pipe

In August, Water Authority crews detected a leak in the 90-inch diameter Pipeline 4, one of five major pipelines the agency operates. The leaky section is near Camino Del Rey in Bonsall, in an area with no adjacent homes or business.

To find the cause of the leak, the Water Authority dewatered the pipe starting Sept. 9. Preliminary results of the investigation are that a weld seam, connecting a steel pipe section to a pre-stressed concrete cylinder pipe, separated in an area of very high water pressure.

The Water Authority is preparing to install a carbon fiber liner to give the pipeline several more years of service while a longer-term solution is developed and deployed.

After repairs are completed, a second 10-day shutdown of Pipeline 4 will be needed to remove the bulkheads and return the pipeline to full, normal operations.

California, like many states, faces an infrastructure crisis, but not just the one affecting the roads we drive on, water systems we rely on, and the electricity that powers our everyday lives. As critical as it is for state and federal policy makers to focus on the resiliency of the state’s infrastructure, we also need to focus on a critical element that often is overlooked: the people who know how to build, maintain and operate the infrastructure we use every day.

California’s infrastructure, from highways to levees to water systems, received an overall grade of “C-” from the American Society of Civil Engineers in its annual evaluation. The Golden State’s airports, wastewater systems and ports received the highest grade at “C+,” while energy came in at a near-failing “D-” in the report released last week. “Recent investments have been made across all 17 categories that comprise the state’s infrastructure network,” the ASCE noted. “However California is playing catch-up after years of under-investment and must identify investment needs for resilient infrastructure in preparation for future natural and man-made disasters.”

OPINION: Newsom Is Shrinking Brown’s Pet Projects

/in , /by /CALmatters (Sacramento)by Dan Walters

When Jerry Brown began his first governorship in 1975, he quickly set himself apart from his father, former Gov. Pat Brown. The elder Brown’s legacy had been an immense expansion of the state’s public-works infrastructure—new colleges and universities, a web of freeways and, most of all, a massive project to carry water from Northern California to the fast-growing cities of Southern California. The younger Brown echoed economist E.F. Schumacher’s aphorism that “small is beautiful,” suggested that California’s high population growth was a thing of the past and virtually shut down highway and freeway construction.
