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.

Bay Area Rainfall: When Is It Coming And When Should We Start To Worry?

/in , , /by /The Mercury News (San Jose, Calif.)by Paul Rogers

Normally between Oct. 1 and mid-November, if historical averages are any guide, the Bay Area has received nearly 2 inches of rain, and Los Angeles and Fresno each have received about an inch.

But so far this year? None.

To be sure, there was one-hundredth of an inch recorded in San Jose and San Francisco — about the thickness of a few sheets of paper — over the past six weeks. But nearly every city from Sacramento to Silicon Valley to San Diego is showing lots of zeros in the rainfall column for the first two months of California’s winter rainy season.

At Least 1,680 Dams Across The US Pose Potential Risk

/in , , /by /AP Newsby David A. Lieb, Michael Casey, and Michelle Minkoff

On a cold morning last March, Kenny Angel got a frantic knock on his door. Two workers from a utility company in northern Nebraska had come with a stark warning: Get out of your house.

Just a little over a quarter-mile upstream, the 92-year-old Spencer Dam was straining to contain the swollen, ice-covered Niobrara River after an unusually intense snow and rainstorm. The workers had tried but failed to force open the dam’s frozen wooden spillway gates. So, fearing the worst, they fled in their truck, stopping to warn Angel before driving away without him.

Volunteer Opportunities At Water Agency Reservoirs In San Diego County

/in , , /by /Water News Network Mentioned: San Diego County Water Authority

People around the world know the San Diego region for its beautiful setting along the Pacific Ocean. But visitors, and even many local residents, aren’t aware of the recreational activities available year-round at area reservoirs.

There are 24 reservoirs in San Diego County. Of these, there are 18 fishable lakes and some offer overnight camping. Popular activities also include boating, kayaking, hiking, and picnicking.

Lake Jennings Reservoir, east of El Cajon, is called a “hidden jewel.” Lake Jennings Recreation Manager Kira Haley admits she didn’t know much about the lake even though she grew up in nearby La Mesa.

Feds Set To Lock In Huge Water Contract For Well-Connected Westlands Water District

/in , , /by /Los Angeles Times by Bettina Boxall

Westlands Water District, a sprawling San Joaquin Valley farm district with ties to the Trump administration, is poised to get a permanent entitlement to a massive quantity of cheap federal irrigation supplies.

Westlands is the first in line to permanently lock in its contract for Central Valley Project deliveries under a 2016 law. Other valley farm districts are expected to follow, but as the project’s biggest customer, Westlands arguably has the most to gain.

The deal would entitle Westlands to annual deliveries that are roughly double what the entire city of Los Angeles uses in a year.

2 Years After Spillway Crumbled, Lessons Learned At Oroville Dam

/in , /by /KCRA 3 (Sacramento, Calif.)by David Manoucherl

It is the tallest earthen dam in the country, standing at 770 feet. The central feature standing over the town of Oroville, the dam brings water and electricity to parts of the state using water from the Feather River.

Today, construction crews are still busy doing some final grading on work that has spanned more than two years. It all began in February 2017 when the main and emergency spillways were damaged. More than 180,000 people were forced to evacuate downstream from the dam.

Sonoma County Drills Wells To Study Groundwater Sustainability

/in , , /by /The Press Democrat (Santa Rosa, Calif.)by Guy Kovner

The shallow wells Sonoma County’s water agency is drilling near 11 waterways have nothing to do with delivering water to 600,000 residents of Sonoma and Marin counties.

Instead, the 21 wells will serve as measuring sticks to determine whether pumping groundwater in the county’s three basins — the Santa Rosa Plain, Petaluma Valley and Sonoma Valley — is curbing the flow in creeks inhabited by federally protected fish and other species.

The $300,000 project is the latest consequence of a state law, enacted during California’s five-year drought, requiring long-term sustainability of underground water supplies that were heavily tapped during the prolonged dry spell.

California Says San Diego County Could Undermine State’s Landmark Plan to Rein In Greenhouse Gases

/in , , , /by /The San Diego Union-Tribune by Joshua Emerson Smith

The stakes are rising in a legal battle over whether San Diego County will be able to approve thousands of new housing units in wildfire-prone areas far from urban job centers using carbon offsets.

The Sierra Club spearheaded the legal challenge last year with support from a host of environmental groups, such as the Center of Biological Diversity, as well as the San Diego-based Climate Action Campaign and Cleveland National Forest Foundation.

While county governments across the state came out early this month in support of San Diego County’s offset plan, Attorney General Xavier Becerra’s office simultaneously blasted the idea — saying it could undercut California’s internationally lauded strategy to reduce planet-warming emissions.

Volunteer Opportunities at Water Agency Reservoirs in San Diego County

/in , /by

People around the world know the San Diego region for its beautiful setting along the Pacific Ocean. But visitors, and even many local residents, aren’t aware of the recreational activities available year-round at area reservoirs.

There are 24 reservoirs in San Diego County. Of these, there are 18 fishable lakes and some offer overnight camping. Popular activities also include boating, kayaking, hiking, and picnicking.

Lake Jennings Reservoir, east of El Cajon, is called a “hidden jewel.” Lake Jennings Recreation Manager Kira Haley admits she didn’t know much about the lake even though she grew up in nearby La Mesa.

“It’s a beautiful resource, and it’s so close to home,” said Haley.

Volunteers help Lake Jennings operations become self-sustaining

Haley arrived in December 2014 with the goal of making the Lake Jennings self-sustaining. Recent park upgrades and an aggressive outreach program have attracted new visitors. The Helix Water District considered closing the park due to financial losses. But in 2018, Lake Jennings Park made a profit for the first time.

Onsite volunteers make a significant contribution to park operations. Onsite volunteers live full-time at Lake Jennings in campers and trailers in exchange for campsite space and electricity. They perform key roles by staffing the information and registration kiosk, monitoring and maintaining the 97 campsites, answering questions, and responding on-call 24 hours. All volunteers receive training in first aid and evacuation procedures.

“We find the volunteers through word of mouth or regular campers who retire,” said Haley. “Some work other jobs and still volunteer 24 hours each week. Their backgrounds are varied. Some have been with us for many years.”

Eight campsites are home to the volunteers, whether individuals or couples. Haley is currently recruiting new volunteers. The Helix Water District oversees the hiring process. Applications are now available on the Helix Water District website jobs page.

“It’s wonderful to live in a place like this in a natural open space situation,” said Haley. “There is a grocery store a mile away, but when you’re here, you feel like you’re in the wilderness. Everyone who comes out here is looking to have a great time. It makes for a wonderful work environment.”

Retired kindergarten teacher Lori Stangel returned to her native San Diego after working in Arizona. She and her husband Chuck found a notice online about Lake Jennings volunteer opportunities and thought the six-month assignment would provide an ideal transition. Five years later, the Stangels are still living and working at Lake Jennings.

“I love nature, and I love being outdoors,” said Lori Stangel. “I love working with the public, and I work for the best staff and administration at Helix you can imagine. They make me feel welcome; it means a lot to me.”

Stangel puts her 30 years of experience as an educator into her volunteer role.

“I get to educate people and families about nature through the outdoors,” said Stangel. “It’s a wonderful opportunity for retired people, but also for young people. They can still go to school or work part-time. It’s a win-win. I’m here because I love it.”

As a Ms. California Senior America pageant competitor, Stangel also spreads the word about Lake Jennings as a valued environmental resource in her personal advocacy platform.

Additional San Diego County Water Authority member agency recreational facilities with volunteer opportunities include Santee Lakes, Padre Dam Municipal Water District, and Elfin Forest Recreational Reserve, Olivenhain Municipal Water District.

Orange County’s Pioneering Wastewater Recycling System Embarks on Major Expansion

/in , , /by /Orange County Registerby Martin Wisckol

Orange County’s wastewater recycling program, a pioneering idea that’s already touted as the largest of its type in the world, is about to get bigger.

Big enough, in fact, to serve the tap water needs of about 1 million residents, according to the Orange County Water District and Orange County Sanitation District. Dubbed the Groundwater Replenishment System, the project produces water that is half the price of imported water, and is virtually immune to both drought and reductions in imports.
