Credit Agencies Cite Water Authority Diversification, Reliability for Strong Ratings

The three major U.S. rating agencies reported strong credit ratings and credit quality for the San Diego County Water Authority kicking off 2022. Newly released analysis by Fitch Ratings, S&P Global, and Moody’s allow the Water Authority to optimize its debt portfolio and minimize the cost of financing vital water reliability projects.

The ratings reports were issued Jan. 27 in anticipation of Water Authority plans to sell $170 million of bonds the week of Feb. 7. Proceeds will be used to finance a portion of the design, acquisition, and construction of various capital projects.

Strong credit ratings

All three rating agencies highlighted the strength of the Water Authority’s significant investments in supply diversification, which allow the agency to meet demands in its service area despite ongoing drought conditions. The Water Authority’s credit quality is deemed strong, in part because the agency adopted its Long-Range Financing Plan in 2021. S&P said, “the LRFP reflects strong management of the authority’s financial and capital needs balanced with long-term affordability for its member agencies.”

Water Authority General Manager Sandra L. Kerl said, “These credit ratings reflect the importance of the Water Authority’s successful effort to diversify the San Diego region’s water supply portfolio combined with strategic financial practices. Consistent investments are protecting the region’s ratepayers from persistent drought conditions while maintaining a safe and affordable water supply.”

Financial leadership, diversified water supply sources

In affirming their credit ratings, the services cited the Water Authority’s financial leadership, including prudent strategies to manage issues related to COVID-19, its success diversifying water supply sources, its commitment to infrastructure maintenance, and its financial reserves for managing contingencies, among other factors.

  • Fitch Ratings affirmed its AA+ rating and gave a stable outlook. Fitch cited the Water Authority’s “strong purchaser credit quality” and “very low” operating costs, as well as a moderate life cycle ratio “reflecting sustained capital investment.” Fitch noted the Water Authority is through the peak of its capital program but retains price risks related to factors such as costs of future water infrastructure investments.
  • S&P Global Ratings revised its long-term outlook to stable from negative for the Water Authority. At the same time, S&P Global Ratings assigned its AAA long-term rating to the agency’s anticipated $170 million series 2022A water revenue bonds. S&P Global noted Water Authority management has “demonstrated an ability to navigate volatile hydrological cycles through adopting rate increases as needed and building prudent financial reserves and storage to mitigate variability.”
  • Moody’s Investors Service reaffirmed its Aa2 rating and stable outlook. Moody’s said, “The stable outlook reflects the likelihood that the Authority’s satisfactory operating performance will remain stable, supported by strong management practices despite challenges associated with ongoing drought conditions, rising costs, and required capital investments.”

Significant projects completed over the past two decades include the San Vicente Dam Raise, Olivenhain Dam, and Twin Oaks Valley Water Treatment Plant. The Carlsbad Desalination Plant has also been completed as a joint project of the Water Authority and Poseidon Water.

(Editor’s Note: All three rating agencies cited ongoing uncertainty resulting from two member agencies’ applications to detach from the Water Authority. Moody’s said detachment could lead to a credit downgrade, which would increase borrowing costs for critical water reliability projects. S&P Global said detachment could challenge affordability and create long-term political risk for the agency, especially if the process sets a precedent that “members can easily detach from the authority.” Information about detachment is at www.sdcwa.org/member-agencies/lafco-reorganization/.)

‘Baking Skills’ Used for Repair at Lake Hodges Pumped Storage Facility

You might not think ‘baking skills’ would come in handy to fix a recent problem at the Lake Hodges Hydroelectric and Pump Station Facility. But those skills, along with initiative and ingenuity, were demonstrated by San Diego County Water Authority staff as part of the creative and complex repair.

The facility connects the City of San Diego’s Hodges Reservoir with the Water Authority’s Olivenhain Reservoir. The connection provides the ability to store up to 20,000 acre-feet of water at Hodges for emergency use.

The Lake Hodges Hydroelectric and Pump Station Facility moves water between Olivenhain and Hodges, and is able to generate up to 40 megawatts of energy on demand, helping to manage electrical demands throughout the County. It also generates revenue and helps offset energy costs.

Ground fault alarm alerts staff

A ground fault alarm on August 25, 2019 alerted staff to a potential problem with Unit 2, one of the facility’s two 20-MW pump-turbine units. A series of tests and inspections by staff with the Water Authority’s Rotating Equipment team discovered the insulation on the copper bus bars of the generator’s rotor were worn and damaged. The bus bars are part of a system that provides DC power to the 12 electromagnets which surround the outer surface of the pump turbine unit’s rotor.

The rotors are designed to spin at 600 revolutions per minute and it’s the rotor’s electromagnets acting upon the stators windings that generates power. The electromagnets are connected together by copper bus bars located on top of the rotor and the bus bars are secured to the rotor by clamping plates and rim studs. The bus bars are insulated to ensure the copper does not touch any other metal surface and cause an inadvertent ground fault.

“Although a single ground fault may not damage the pump-turbine unit, it may prevent it from starting, if two ground faults were to occur, significant damage to the pump-turbine unit would occur and would also be an extreme danger to anyone within the facility,” said Jim Fisher, Water Authority director of operations and maintenance.

Creative solutions and ingenuity save time, money

Among various factors, the primary cause of the insulation failure was determined to be improper wrapping and curing of the insulation during initial installation.

Water Authority staff developed solutions and also took on the repair tasks in September. By doing the work in-house, the Water Authority avoided a more extensive outage due to long lead times required by contractors and vendors to perform the same work, saving time and money.

“Staff did an excellent job maintaining the operation of Unit 1 while making the repairs to Unit 2,” said Fisher, “which allowed the Water Authority to avoid a total shutdown and loss of all revenue during this period.”

‘Baking skills’ come in handy to create new bus bars

New copper bus bars were fabricated, and each had to be precisely wrapped by 5 different types of insulating tape materials. This wrapping process alone took approximately 8 hours per bus bar. The bus bars were then baked for ten hours within newly designed and fabricated aluminum molds to ensure proper pressure was applied to the insulation layers during the baking and curing process.

Staff efficiently re-purposed and utilized an oven that had been retained from the San Vicente Dam Raise Project to perform the baking. The Rotating Equipment team’s efforts produced excellent quality results which would have been difficult even for a vendor to meet. The newly insulated bus bars were re-installed, and the unit has been operating safely and without issues.

The initiative, ingenuity, and highly technical skills and knowledge of our staff were once again on display throughout the repairs,” said Fisher. “Their dedication, talents and outstanding efforts continue to ensure the Facility’s efficient and safe operation.”

Unit #2 was tested and placed back into service on November 17, 2019.

Along with the bus bar insulation and curing process repair, staff also performed many other highly technical, innovative and precise processes to complete this repair work.

San Diego’s Water Portfolio Approach ‘Model for California’

State officials Thursday toured San Diego County water infrastructure to get a first-hand look at the region’s successful water portfolio approach for supply diversification.

California Natural Resources Agency Secretary Wade Crowfoot, Deputy Natural Resources Secretary Thomas Gibson, State Department of Food and Agriculture Secretary Karen Ross, and State Water Resources Board Chair E. Joaquin Esquivel were here to assess the region’s water projects as part of their new role in developing a water portfolio strategy for the state.

Portfolio approach benefits region

“The region is proof that the portfolio approach works,” said Water Authority Board Chair Jim Madaffer. “The Water Authority and its 24 member agencies continue to develop local projects and explore opportunities that would benefit the region, the state, Mexico and the Southwest.”

At a luncheon meeting and panel discussion at University of California, San Diego following the tour, the agency officials joined a group of more than 150 people to hear how the portfolio approach can help California and the Southwest meet water supply challenges.

Along with the Water Authority Board of Directors, elected officials, business, community and state and local leaders gathered in an auditorium at the Southwest Fisheries Science Center on the La Jolla campus.

Jim Madaffer and Water Portfolio approach

“The state needs to look at a global approach to managing water,” said Water Authority Board Chair Jim Madaffer.

Madaffer said during the meeting that San Diego’s portfolio approach has been successful in increasing the region’s water supply reliability through diversification and innovation.

“The Water Authority’s model is one that can be replicated across the state to help ensure a secure water future for all Californians,” said Madaffer.

State agency leaders echoed Madaffer’s comments.

“San Diego has been a leader in the water portfolio approach,” said Wade Crowfoot. “We have to make the investments to build regional water resilience as part of the Governor’s order to develop a portfolio to manage water in California.”

Water resilience portfolio for 21st century 

The Water Authority invited the officials to visit after Gov. Gavin Newsom issued an Executive Order in April, directing state agencies to “prepare a water resilience portfolio that meets the needs of California’s communities and environment through the 21st century.”

In his May letter to Newsom, Madaffer thanked the governor for the “wisdom and leadership” with the issuance of Executive Order N-10-19, and invited the governor to tour San Diego County’s cutting-edge water facilities.

Newsom’s order also directed his administration to “identify and assess a suite of complementary actions to ensure safe and resilient water supplies, flood protection and healthy waterways for the state’s communities, economy and environment.”

The California Natural Resources Agency, the California EPA, and the California Department of Food and Agriculture, in consultation with the Department of Finance, were directed by Gov. Newsom to, among other tasks, “identify key priorities for the administration’s water portfolio moving forward.”

“Governor Newsom wants us to think long and broadly on water,” said Crowfoot. “He wants us to get away from the silos and conflicts on water in California – the mindset of environment groups versus farmers, north versus south, urban versus rural – and work together on water resiliency.”

Significant investments in regional water strategy

“The Water Authority and its 24 member agencies have made significant investments in the last two decades to diversify our water supply, creating a portfolio of resources to support our region’s 3.3 million people and $231 billion economy,” said Madaffer.

During the tour, the officials got a first-hand look at some of those investments, including the San Vicente Reservoir, Olivenhain Reservoir, and the Claude “Bud” Lewis Carlsbad Desalination Plant.

Global Warming creates water supply challenges

Scripps Institution of Oceanography research meteorologist Dan Cayan told the audience that temperatures and dry spells will increase in California in the future, making water storage, conservation, and forecasts even more critical.

“Global warming climate models show the Sierra Nevada snow pack will be 50% less in 2090 than today’s average April 1 snowpack,” said Cayan.

Cayan said observations and climate model projections indicate climate change is occurring and will grow stronger. California should expect 1.5-2 degrees Fahrenheit warming by 2050, he said.

New regional pipeline study

Water Authority Assistant General Manager Dan Denham described a new study that will explore the viability of a regional pipeline to transfer water from the Colorado River to benefit multiple users in San Diego County and across the Southwest.

The pipeline system is one of a handful of ideas being discussed by San Diego County water leaders to enhance partnerships and solutions that make sense locally and more broadly as part of Governor Newsom’s Water Portfolio Program to develop resiliency statewide.

Map indicates three potential routes for a proposed regional pipeline system that would move Quantification Settlement Agreement water directly from the Imperial Valley to San Diego. Two of the routes (the light blue and purple lines) follow a southern route. The third proposed route, (shown in both a yellow and darker blue line) follows a northern path. Graphic: Water Authority

Creating a pipeline to transfer Colorado River water to the San Diego region has been studied periodically over decades.

But the new study is focused on how a regional pipeline could provide multiple benefits as part of a long-term water management strategy for California and the Southwest.

The expanded review will consider a system that could create much-needed storage opportunities for the Imperial Irrigation District that could support agriculture while addressing critical issues like the Salton Sea and the need for more renewable energy development.

The San Diego County Water Authority’s Board of Directors celebrated the agency’s 75th anniversary.

Water Authority Celebrates 75 Years of Service to San Diego County

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.”

San Diego County Water Authority service sArea and 24 member agencies

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.

San Vicente Dam raise

  • 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.
