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 /Water News Network Mentioned: San Diego County Water Authority

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.

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.

The latest ‘Work We Do’ video in the series features a recent valve replacement

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.

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.

Trenchless Technology Saves Ratepayers Time, Money, and Inconvenience

/in , /by

A method of replacing sewer pipe without digging or removing the old pipe – trenchless pipe repair – is saving Vallecitos Water District ratepayers money and reducing traffic delays. It’s another example of how water agencies in San Diego County are tapping cost-effective technology.

The district is using the trenchless method to extend the life of its service pipelines while avoiding the disruption of excavation trenches and traffic rerouting around work areas on public streets. Instead of digging the pipeline up to replace it, the sewer line is rehabilitated from inside the pipe. This trenchless technology method increases the efficiency and the service life of the pipe without having to replace it; eliminating paving, reducing traffic interruptions, as well as saving the District and in turn its ratepayers money.

“Traditional installation methods cause such a disruption to customers daily routine, so we’re really lucky when this type of project presents itself to the District,” said Jason Hubbard, a senior engineer with the district. “Our residents are going to have a much better day without navigating a large construction zone – they can also be quite noisy and dusty. Bottom line, everyone’s happy.”

Pipeline integrity can be lost due to a combination of many factors such as missing pieces, cracks, pinholes, offsets at joints, and root intrusion. Numerous methods, technologies and practices are used by water agencies to ensure pipeline integrity.

The Vallecitos Water District works to find innovative technologies to ensure continuing water, wastewater, and reclamation services to a population of 103,000 residents within its 45-square-mile service area. There are 358 miles of water pipelines and 276 miles of sewer pipelines in the VWD’s 45-square-mile service area, serving more than 103,000 residents. The pipelines are designed, built, and operated to be safe, reliable, and sustainable to achieve pipe integrity. This means ensuring a pipeline and all its related components are running properly, no small task.

“We constantly work to maintain a reliable sewer conveyance system by utilizing a plethora of innovative and cost-effective technologies,” said Hubbard.

Trenchless technology also results in cost savings

VWD employed two types of trenchless rehabilitation methods, cured-in-place-pipe (CIPP) liners and spiral wound liners to maintain District pipes. CIPP liners are epoxy saturated felt tubes, which are inserted into the existing pipe, then cured and hardened by steam. There are no joints or seams. Spiral Wound Liners use an above groundwinding machine to feed interlocking PVC profile into an old pipe.

Both methods result in a new “pipe within a pipe.” Little to no digging is involved in this trenchless process, making for a less disruptive and more cost-effective method than traditional “dig and replace” pipe repair methods. The liner can be inserted using water or air pressure. Liner technology is particularly effective in hard to reach areas, such as easements. For projects along residential and business streets, the trenchless method reduces disruptions and impacts to businesses and neighborhoods.

This technology helped the Vallecitos Water District to rehabilitate 1,595 feet of sewer pipe. The district plans to rehabilitate another 2,300 feet in 2020. Sections of critical infrastructure were rehabilitated at an affordable price due to the CIPP and spiral wound liner options. No sewer laterals were cut, and work was done without a sewer bypass. The project was completed with a savings to the District of $37,000 under the estimated budget. The lining part of the operation took less than three hours.

Vallecitos Water District Smokes Out Wastewater System Problems

/in , /by

Problems in wastewater systems can’t hide behind a smokescreen at the Vallecitos Water District. The district’s Systems Collection Department routinely performs “smoke testing” of its wastewater system. This technique can easily locate flows caused by broken or incorrectly installed sewer pipes, lateral connections, or missing/broken clean-out caps.

The test is performed by introducing smoke, comprised primarily of steam, through a device similar to a fog generating machine, into the wastewater systems. Staff can see if smoke comes out of the system through any leaks or breaches.

“We don’t want clean rainwater entering the sanitary sewer system, because we don’t want to treat clean water down at the treatment plant,” said Matthew Thompson, VWD wastewater collection worker. “We also don’t want to have an open system in case of an emergency, where liquids could exit the system.”

Residents are notified prior to any smoke testing in their neighborhood. The use of the smoke is an approved practice by the U.S. EPA and has no adverse health effects. The smoke used by VWD is non-toxic and dissipates quickly. During the testing process, residents can assist by monitoring the plumbing systems inside their homes to see if they have any internal problems.

Watch how the smoke testing process works in this video.

Crews inject smoke into the sewer system. It bypasses the living quarters of each residence before rising out of vents located on the roof. This is what crews are looking for, because it’s a good indicator there are no illegal hookups to the sewer. Smoke may also escape if the private sewer lateral clean-out is missing its cap.

If smoke emits from the home’s storm drain system or front yard, it could mean there is a possible illegal system connection, or an opening to the sewer that can lead to surplus water levels and subsequent sewer spills.

Field crews take care of any problems that may arise during testing. Residents are notified to disconnect illegal connections or face potential future fines. While the district does not maintain the plumbing inside homes, including the sewer lateral or the clean out, district crews will make simple, inexpensive repairs on the spot as a service to their customers. A doorhanger is left after any quick-fix is completed.

“Our ultimate goal is to make the customer happy, and that there is no interrupted service,” said Thompson. “If you see any of the wastewater crew out in the street, feel free to come talk to us and ask us what we’re doing. We’d love to share how we’re helping the system flow.”

In some cases, customers identify sewer problems themselves. District Systems Collection Department staff then determine the source of any potential problems, and how to resolve those problems.

Smoke testing isn’t new, but it might catch residents off guard. It has been used since the 1950s. For more than 10 years, smoke testing has proved to be a valuable ally in sewer maintenance. The Vallecitos Water District performs a minimum of four tests annually to keep its system operating at the optimum level.

San Diego County residents have embraced the new WaterSmart approach to their landscaping, installing water-efficient gardens and removing thirsty turf in increasing numbers.

One of those swapping turf for sustainable landscaping is San Marcos homeowner Rhonda Holmes. She won the 2018 Vallecitos Water District Landscape District contest. Holmes transformed the landscape at her home shortly after buying it. Her outdoor remodel included replacing the front and backyard turf areas with water-efficient plants.

She designed a garden that was smart on water while being beautiful at the same time.

“It’s really easy to do,” Holmes said. “I’d love to see more people try to do their part.”

The contest aims to inspire residents to consider a landscape makeover by showcasing the beauty and variety of water-efficient landscapes.

Many previous winners have taken advantage of the San Diego County Water Authority’s free WaterSmart landscape makeover classes to help them successfully create and complete their projects. More than one million square feet of turf has been targeted for removal by course participants, generating a water savings potential of 36 million gallons annually.

Interested residents can learn about the next series of Landscaping Makeover classes and register on the WaterSmartSD website.

In addition to the benefits of reducing water consumption, water-efficient landscaping can improve a home’s curb-appeal and value, and reduce the need for costly, time-consuming maintenance. Many native plant selections also have fire-resistant qualities and provide habitat for local wildlife.

Outdoor watering accounts for roughly half of statewide urban use, and more in inland areas, according to a Public Policy Institute of California report. Savings can come from installing more efficient irrigation systems and replacing thirsty lawns with less thirsty plants.

The winners are:

First place – Rhonda Holmes and Jeff Jenco

Second place – Dennis and Shannon Root

Third place – Patti Joyce and Jeffrey Moore

View a video tour and interviews with the winners here.

First place winner Rhonda Holmes said the landscape transformation at her Lake San Marcos-area home took place after purchasing the house and undertaking a complete remodel, which included replacing the front and back yard turf areas with water-efficient plants.

Holmes describes seeing neighborhood lawns with running sprinkler heads misting the streets. She wanted to design a garden that was smart on water, while being beautiful at the same time. As for the earth-friendly garden remodel, Holmes says, “It’s really easy to do. I’d love to see more people try to do their part.”

Bioswale feature prevents stormwater pollution

Holmes also installed a beautiful and environmentally conscious bioswale to reduce pollution to nearby Lake San Marcos. It prevents water from being emptied into the storm drain system.

“I think what people don’t realize is all the pesticides and fertilizers and chemicals we use on our plants, if we don’t do something like a biofiltration system with those chemicals, then end up leaching out into the streets, into the gutters and into the golf course here, and for example in Lake San Marcos,” said Holmes.

Holmes says in addition to water conservation, she is able to avoid pest control with chemicals, because native plants are more disease resistant.

All three winners experienced an unexpected benefit: an influx of wildlife into their yards including birds, bees and butterflies, and small reptiles. There is even a neighborhood peacock that visits the Root household.

Free fall series of landscape makeover classes now open for registration
