/in , /by

The San Diego County Water Authority’s Board of Directors celebrated the agency’s 75th anniversary during today’s Board meeting, which included 20 proclamations honoring the agency for its service to the region dating back to 1944.

Cities across the region joined the state Assembly and Senate, the San Diego County Board of Supervisors and other state and local leaders to formally mark the occasion. The San Diego City Council and the San Diego County Board of Supervisors even proclaimed today “San Diego County Water Authority Day” in honor of the agency’s legacy of water supply reliability.

75 years of service

“Starting with the historic first water deliveries in the 1940s, the Water Authority has partnered with our member agencies to build, operate and maintain the vital infrastructure that supports our region’s $231 billion economy and unparalleled quality of life,” said Board Chair Jim Madaffer. “Our collective investments have created extraordinary advances in water supply reliability that are sustained by the daily vigilance necessary to operate and maintain such a complex system.

“While today we celebrate the past, the Water Authority and its 24 member agencies continue to focus on the future by fostering innovative solutions to ever-changing water resource challenges,” Madaffer said. “Together, we will supply the San Diego region with safe and reliable water supplies for generations to come.”

Since 1991, the Water Authority and its 24 member agencies have deployed one of the most aggressive water supply diversification strategies in the nation to improve regional water supply reliability. In the years ahead, member agency projects will play an increasingly important role in continuing to ensure reliability for the San Diego region.

Forward thinking on water

The Water Authority’s current forward-thinking efforts include developing water storage capacity in Lake Mead to provide additional drought resilience for San Diego and the Southwest.

The agency also is working closely with the City of San Diego to assess a potential pumped storage project at San Vicente Reservoir that could help meet clean energy goals and benefit water ratepayers. In addition, the Water Authority is analyzing the costs and benefits of a regional water conveyance system that could help San Diego County and the entire Southwest to more effectively manage water resources.

Profound impact

During today’s ceremonies, water agency, civic and business leaders noted the Water Authority’s profound impact on the San Diego region and wider water issues over the past 75 years.

  • “A reliable water supply is critical for San Diego’s regional economy and for maintaining a competitive business climate. The business community applauds the Water Authority and its 24 member agencies for their leadership, and for increasing the county’s water supply reliability with investments that keep our economy growing.” — Mark Cafferty, president and CEO, San Diego Regional Economic Development Corp.
  • “It is a pleasure to celebrate the San Diego County Water Authority’s 75th anniversary. We share a common history and a common vision for water supply reliability that has been essential to the economic vitality and prosperity to all San Diegans. We look forward to strengthening our relationship to meet the future needs of San Diegans.” — Gloria D. Gray, chair, Metropolitan Water District Board of Directors
  • “Farming is a foundational piece of our regional economy and quality of life – but it doesn’t happen without a reliable water supply. Our farmers are constantly innovating to use water more efficiently by adopting new technology and planting more-efficient crops.” — Eric Larson, executive director, San Diego County Farm Bureau
  • “On behalf of the Imperial Irrigation District Board of Directors, I salute the San Diego County Water Authority on its 75th anniversary. Our two agencies are partners in the nation’s largest agriculture to urban transfer and in the process, we have forged a durable alliance at the Salton Sea. It is a relationship that the IID highly values.” — Erik Ortega, president, Imperial County Irrigation District Board of Directors
  • “By combining a diversified set of water supply sources with greatly enhanced storage capacity, we are developing a more robust safety net for San Diego County.” — Jerry Sanders, president and CEO, San Diego Regional Chamber of Commerce

On June 9, 1944, San Diego voters approved the Water Authority’s formation under the County Water Authority Act. Imported water arrived three years later to slake the thirst of a growing population just weeks before local supplies would have run out.

The modern era of the Water Authority started during deep, drought-induced water supply cuts in the early 1990s. Since then, Water Authority and its 24 member agencies have deployed one of the most aggressive water supply diversification strategies in the nation to improve regional water supply reliability.

At the same time, the agencies have aggressively helped to reduce per capita water use so that the total regional water use today is well below 1990 levels despite significant growth in the population and economy.

75th anniversary milestones

The Water Authority reached several major milestones over the past two decades. They include:

  • In 2003, Olivenhain Dam was the first major new dam built in San Diego in more than 50 years. At 318 feet, it was the tallest roller-compacted concrete dam at the time.
  • In 2008, the Twin Oaks Valley Water Treatment Plant north of San Marcos began operations. It was the largest submerged membrane water treatment plant in the world when it was commissioned.
  • In 2011, the San Vicente Tunnel and Pipeline Project – an 11-mile long, 12-foot diameter tunnel with an 8-1/2-foot diameter pipeline – created a link from the City of San Diego’s San Vicente Reservoir to the Water Authority’s Second Aqueduct, greatly improving the Water Authority’s ability to distribute water and store water in the reservoir.

  • In 2012, the Lake Hodges Hydropower Facility started serving the dual purposes of connecting the lake to the Water Authority’s aqueduct system and generating 40 megawatts of clean, on-demand electricity.
  • In 2014, the San Vicente Dam Raise Project, the tallest dam-raise project in U.S. history, expanded the reservoir’s capacity by more than 157,000 acre-feet.
  • In 2015, the $1 billion Claude “Bud” Lewis Carlsbad Desalination Plant, distribution pipeline and related facilities started commercial operations as the largest seawater desalination project in North America.
  • The Water Authority’s Asset Management Program, which includes a multi-year project to reline 82 miles of large-diameter prestressed concrete cylinder pipelines with new steel liners, helps to prevent pipeline failure and extend their lifespans by 75 years or more at significantly less cost than traditional pipeline replacement programs.

Worldwide recognition

The Water Authority’s innovative efforts have been recognized nationally and internationally.

In 2017, for instance, the president of the American Society of Civil Engineers recognized the Water Authority’s Emergency & Carryover Storage Project for winning ASCE’s top international engineering award.

The same year, Water Authority was honored by the Association of California Water Agencies – the nation’s largest statewide coalition of water agencies – for innovation and excellence in water resources management with its addition of supplies from the Carlsbad Desalination Project. And in 2016, the Water Authority received a top national award from the Association of Metropolitan Water Agencies for its commitment to improving the region’s water supply reliability in a manner that balances economic, social and environmental needs.

Water Authority Supports Bill to Spur Pumped Storage Projects

/in , /by

A bill that the San Diego County Water Authority’s Board of Directors voted to support in March is scheduled for a hearing Thursday in the state Senate Appropriations Committee. The proposed state legislation promotes the development of pumped hydroelectric storage projects to help meet state energy and climate goals.

Senate Bill 772 by Sen. Steven Bradford of Gardena promotes the development of pumped hydroelectric storage projects to help meet state energy and climate goals.

The Board’s support for the legislation followed the March release of a research paper from a team led by UC San Diego Professor David G. Victor that emphasizes the benefits of expanding pumped hydro energy storage as a cost-effective way to help California meet its renewable energy goals and reduce greenhouse gas emissions.

Read the Pumped Energy Storage report here.

The Water Authority and the City of San Diego are exploring a potential pumped storage energy project at the San Vicente Reservoir that could store 4,000 megawatt-hours per day of energy, or 500 megawatts of capacity for eight hours.

Energy generated by renewable sources, like wind and solar, can be captured by energy storage facilities and then distributed then needed. Batteries and pumped energy storage will provide the needed energy storage for both short-term needs (batteries, less than 4 hours) and long-duration needs (pumped energy storage, 8 hours or more).

Large-scale, long-duration renewable energy source

A key to the San Vicente concept and others is development of statewide institutional and regulatory support for large-scale, long duration energy storage lasting up to eight hours. Pumped storage projects store solar and wind power during low-demand periods for use during high-demand periods, such as evenings when people are cooking, washing clothes and running air conditioners.

The State Energy Resources Conservation and Development Commission has identified bulk energy storage – including pumped hydroelectric storage – as a core strategy for integrating renewable energy resources into the California electrical grid and reducing greenhouse gases.

In addition, the white paper stresses the need for new state policies that will ensure that pumped energy storage projects enter commercial operations when they will be critically needed.

“To be consistent with California’s energy vision, active new policy support is needed to facilitate the development of pumped energy storage,” according to Victor’s paper. “Those policies should recognize the long lead times in building pumped energy storage projects (5 to 10 years). New policy efforts must begin now.

“Among the needed actions are state-backed support for some early projects that would jump start investment in this proven technology. This support can demonstrate viable business models and investment strategies that will pave the way for more private sector-led projects in the future.”

Providing ratepayer benefits

Pumped energy storage projects work like giant batteries by storing excess renewable energy during the day, when renewable power production peaks. Energy is released from the “battery” in the evening, when energy use increases, and renewable energy is not available.

Keeping the electrical grid reliable requires not only short-term energy storage, but long-duration, large-scale storage.

“Many expert studies have been performed that demonstrate the value of pumped energy storage, including CAISO’s Bulk Energy Storage Case Study, which found that a 500 megawatts (MW) pumped energy storage project in Southern California would provide ratepayers with a savings of up to $51M per year from improved efficiencies in system operation,” according to Victor’s white paper.

“Without significant new large-scale energy storage, California will likely be required to import more energy from other states, including potentially power generated with higher carbon emissions, such as coal,” the paper said. “The State will be unable to meet its renewable and climate goals reliably without large-scale energy storage.”

SB 772 is an attempt to address some of the issues identified by Victor and others. The legislation would require the California Independent System Operator, which runs the state’s power grid, to create a competitive bidding process by June 2022 to acquire a substantial quantity of long-duration energy storage – the type created by pumped hydroelectric storage.

San Diego County Students Shape the Future of Water

/in , /by

On April 25, the San Diego County Water Authority Board of Directors honored the latest group of water-related award winners from the Greater San Diego Science and Engineering Fair as part of the agency’s effort to inspire young people to pursue water industry careers.

This year’s middle school and high school science and engineering projects displayed a wide range of innovative ways to solve a variety of water issues people face today.

In the senior division, Alfred and Audrey Vargas won the first place award with the design of a new device to treat wastewater and generate electricity simultaneously using hydrogen fuel cell technology. The siblings, who attend Sweetwater High School, also won their division last year and continue their work in designing devices and systems that can potentially be used in developing countries where resources are scarce.

Alfred and Audrey have been competing in science fairs since they were in middle school and have always been inspired by a drive to solve world water issues in affordable ways.

“As we’re looking for the next generation of water industry professionals, events like the Greater San Diego Science and Engineering Fair are the perfect opportunity to connect with and support students who are already interested in relevant water issues,” said Water Authority principal public affairs representative Risa Baron, who helped select the winners. “These young thinkers and inventors can make huge strides in solving future water challenges around the world.”

Finding inspiration in the natural world

Cambridge School student Emily Tianshi won the second place award in the senior division. She looked beyond the ocean views at Torrey Pines State Park to see the intelligent ways that nature sustains itself and how those can be imitated.

Emily spent the past three years perfecting a design for a device that can capture moisture from the air like Torrey Pine needles do. Using 3-D printing technology to bring her project to life, Emily demonstrated that the naturally occurring ridges of Torrey Pine needles efficiently collect water, and she designed a model of a device that would mimic the shape of the needles.

In the junior division, Brendan Cordaro and Max Shaffer from Saint John School in Encinitas teamed up to win first place with “The Water Maker,” a homemade device that transformed a miniature refrigerator into a means of collecting water from the air.

Oliver Trojanowski, who is also a middle school student at the Saint John School, won the second place award in the junior division. Oliver surveyed several sites in the region to test for water quality and determine toxicity levels in stormwater runoff.

Matthew Angulo from the Corfman School in El Centro earned the third place award in the junior division. He travelled over 100 miles to showcase his results from several tests of water samples from the Colorado River.

Welcoming the next generation of water professionals and leaders

More than 2,800 people across all levels of educational attainment work at the Water Authority and its 24 member agencies to provide safe and reliable water supplies to the region.

The Water Authority and its member agencies are committed to fostering the next generation of industry professionals and leaders. Engineers, system operators, maintenance technicians, customer service representatives and utility workers are just some of the many careers available in the water industry.

Water Authority Seeks Statewide Solution to Drinking Water Woes

/in , /by

The San Diego County Water Authority’s Board of Directors on March 28 threw its support behind a coordinated statewide approach to ensure that all communities in California have daily access to safe, reliable drinking water.

The California State Water Resources Control Board has identified 329 water systems statewide that serve contaminated drinking water or cannot provide reliable water service due to unsound infrastructure or lack of resources. Most of the systems are in rural areas and serve fewer than 10,000 people.

More than a half-dozen bills have been introduced in Sacramento this legislative session to provide safe and reliable water supplies for disadvantaged communities in the Central and Salinas Valleys.

The Water Authority Board supports a plan to combine several measures into a unified legislative package.

“By amending several components of the relevant bills and linking them in a modified single reform package, we would advance a more comprehensive fix to drinking water quality issues throughout the state,” said Glenn Farrel, government relations manager for the Water Authority.

Safe Drinking Water Trust Fund

In addition, the Water Authority Board voted to support Senate Bills 414 and 669, both of which provide alternatives to water tax proposals in the Legislature that the agency helped defeat last year.

  • SB 414 would establish the Small System Water Authority Act of 2019 and authorize the creation of small system water authorities that could absorb, improve and competently operate public water systems that are chronically out of compliance with drinking water standards.
  • SB 669 would create the Safe Drinking Water Trust Fund to collect federal contributions, voluntary contributions, gifts, grants, bequests, transfers by the Legislature from the General Fund and the Greenhouse Gas Reduction Fund, funding from authorized general obligation bond acts, and other sources. Revenues would help community water systems in disadvantaged communities that chronically fail to meet federal and state drinking water standards and do not have the money to pay for operation and maintenance costs to comply with those standards.

The Water Authority Board voted to oppose SB 200, unless it is amended to address numerous concerns that are outlined in the staff report to the Water Authority’s Board.

A fourth legislative measure, an Administration Budget Trailer Bill: Environmental Justice – Safe and Affordable Drinking Water and Exide Cleanup, would impose a tax on water and agricultural activities to finance safe drinking water efforts. The Board voted to oppose the budget trailer bill unless it is amended, among other things, to remove water tax provisions and instead appropriate $1 billion in budget surplus funds to the Safe Drinking Water Trust Fund.
