In Quest for Bigger Batteries, California Mulls Century-Old Idea

As the sun sets on California’s solar farms, a backup energy source deep in the Sierra Nevada Mountains springs to life. The huge system of reservoirs and turbines can store energy during the day and then crank out electricity for 900,000 homes, using just water and gravity.

As the state tries to make wind and solar work around the clock, officials want to build more like it. It won’t be easy: such projects take years to develop, are expensive and face stiff opposition.he push by California and other states to revive the century-old technology — called “pumped-hydro storage” — underscores the limitations of modern batteries.

Inspecting Steel Pipelines To Safeguard San Diego’s Water Systems

One of the perks of working in trenchless technology is the ability to get outside and get your hands dirty while safeguarding our community’s infrastructure. That holds doubly true when working in sunny southern California in November. Over the course of 23 days, San Diego County Water Authority (SDCWA) worked with PICA USA to inspect six miles of steel pipeline and ensure its underground assets can be operated safely for years to come. The SDCWA owns and operates more than 310 miles of pipeline serving the San Diego region, conveying water to 24 member agencies. The WA’s pipeline network ranges in size from 39 in. to 120 in. and is comprised of a variety of materials, including PCCP, steel, RCCP and others.

Many homeowners are eager to create a beautiful new sustainable landscape on their own, with guidance from organizations like the San Diego County Water Authority. But sometimes it’s a smart idea to call on professionals trained in different aspects of the watershed approach to landscaping. With a little help, you can ensure the success of your project.

Assessment organizations including site assessment and testing, various measuring services, surveyors, soil testing services and even Google Maps are available. Property measuring and survey companies can develop more detailed site plans with elevations, siting of trees and landscape amenities.

Planning and design professionals can help you develop a working plan and budget for your landscaping. The plan should include drawings, resource lists, and an outline of the techniques needed to implement the plan. Landscape designers and architects can help you create a conceptual design. Working with a licensed professional is recommended if you have hillsides and slopes, or complicated structures.

Landscape installation and construction professionals are licensed contractors who specialize in building landscape, and can work on all aspects of a sustainable landscape plan. You may be able to install your own garden, but if you get stuck you can call upon the expertise of an experienced pro who carries all the necessary insurance and is knowledgeable about permitting requirements.

Rainwater catchment specialists include people certified by the American Rainwater Catchment Systems Association (ARCSA) to design and install rainwater capture systems. These pros can bring specialized expertise to your project, particularly if it involves installation of an active capture system such as a cistern. The water savings you achieve can offer you a solid return on investment.

Irrigation system consultants include people with certification by an EPA WaterSense ® organization to provide irrigation system auditing, design, and maintenance. They can help you improve the efficiency of your irrigation system. The Irrigation Association, California Landscape Contractors Association Water Managers, Qualified Water Efficient Landscapers, and G3 Watershed Wise Landscape Professionals all provide searchable lists of qualified people.

Plant selection specialists include your local retail nursery and garden center, native plant societies, Master Gardeners, and professional gardeners. Learn from them, and do your homework to select plants that are both climate appropriate and locally native to your area, and you will be rewarded with a better understanding and appreciation of your garden as it evolves over the years.

Maintenance of sustainable landscapes requires an understanding of the watershed approach to landscaping and water management. Even if you eliminate the need to mow a lawn, there remains the need for fine pruning, irrigation tune-ups, cleaning and checking water retention devices, and soil building. Maintenance people must have the know-how to implement mulching, basic irrigation adjustments, and care of native plants.

Certified arborists are specialists trained in the art and science of planting, caring for, and maintaining individual trees. Find qualified professionals at the International Society of Arboriculture (ISA) and the American Society of Consulting Arborists (ASCA).

Take advantage of the public education provided by your local water district, various nonprofit organizations, and the San Diego County Water Authority. Classes are often free of charge. For more information, visit WaterSmartSD.org.

California Reservoirs Near Capacity in May

It has been a winter – and spring – for the record books, for California reservoirs and ski resorts. And, it’s not over yet.

Snow has continued to fall throughout May, with several inches or more in the Sierra Nevada and the southern California mountains.

In the lowlands, the City of San Diego has experienced one of its wettest months of May on record. The San Diego National Weather Service reported that Alpine and El Cajon set daily precipitation records on May 23.

The normal rainfall at Lindbergh Field during the water year (October 1 – September 30) averages about 10.3 inches. In the current water year, 12.7 inches of rain has been recorded at Lindbergh Field as of May 23.

May snowfall in the Sierra Nevada

“It’s atypical to see the snowpack increase in May,” said Alexi Schnell, water resources specialist with the San Diego County Water Authority. “The impact of atmospheric river storms helped push snowpack levels in the northern Sierra to 172 percent of normal as of May 23.”

Record snowfall also allowed many ski areas, from Squaw Alpine to Mammoth Mountain, to extend their ski seasons into late-Spring, with fresh powder in May a bonus for skiers.

A May to remember at Mammoth Mountain

Mammoth Mountain tweeted that it has received 29 inches of snow as of May 23, “officially our snowiest May on record, beating out May 2015.” (Video courtesy of Mammoth Mountain).

Major reservoirs near capacity

Many of the state’s major reservoirs are near capacity and are significantly above their historical averages as of May 23. Lake Shasta is at 97 percent of capacity and at 113 percent of its historical average.

Most major California reservoirs are near capacity and significantly above historical averages for May 23.

Summer is coming

Schnell cautions that this current water year is an exception, and the climatological cycle in California can bring several consecutive years of drought, like the 2015-2017 period, which prompted mandatory water-use reductions.

While the winter and spring has been ‘atypical,’ the summer could set some records too.

“Looking ahead over the next three months, the National Weather Service forecast shows that there is a greater than 50 percent chance the region will be warmer than normal,” Schnell said.

Water Authority Recommends $1.7 Billion Two-Year Budget

San Diego – The San Diego County Water Authority’s Acting General Manager today recommended to the Board of Directors a $1.7 billion budget for fiscal years 2020 and 2021, up 5 percent from the current two-year budget, due largely to increasing costs for water supply, supply reliability and infrastructure improvements.

Water Authority staff also proposed increasing rates and charges for member agencies by 4.3 percent for treated water and 4.8 percent for untreated water in calendar year 2020, attributable to rate increases by the Metropolitan Water District of Southern California, continued investments in supply reliability, and reduced water sales that lower demand and mean fixed costs must be spread over fewer gallons.

Aging Water Workforce Spurs Industry Recruiting Efforts

A flood of water industry professionals nearing retirement has prompted local agencies to form a task force charged with assessing ways to develop the water workforce of the future. Education leaders are stepping up outreach to fill their career training programs, and water agencies are looking for new ways to attract employees.

“For many years now, we’ve been talking about the ‘Silver Tsunami’ of aging baby boomers who are going to be leaving the workforce, but it really is coming to fruition now,” said Don Jones, who helped spearhead Cuyamaca College’s new Center for Water Studies housing the college’s Water & Wastewater Technology program. “Almost one-third of water industry professionals will be at or nearing retirement age in the next few years. When you combine that with the fact that the unemployment rate is already at record or near-record lows and other industries are facing the same challenges and going after the same people we are, we have some serious work to do.”

Those concerns have spurred the San Diego County Water Authority and other agencies to convene a regional task force comprising utility directors and general managers, which has been meeting for months to assess workforce-related challenges, collect and analyze employment data, and craft a plan for moving forward.

Water industry offers competitive salaries

The regional water and wastewater industry expects to need to fill approximately 400 positions annually to keep pace with retirements and vacancies caused by employees leaving the area.

The challenges face both large and small agencies. In the City of San Diego, 640 of approximately 1,600 water industry professionals will be eligible to retire within the next three to four years. At the Fallbrook Public Utility District approximately 40 percent of the agency’s 68 employees will be eligible to retire within five years. Seventeen percent are currently eligible for retirement.

“These are good-paying jobs with good benefits, but you just don’t find a lot of people coming out of school who are interested, and we are struggling to attract skilled employees from the private sector,” said Jack Bebee, Fallbrook general manager.

Bebee pointed to the recent posting of a senior engineering position at the utility that pays an annual salary of close to $150,000. The district thought the salary would be competitive enough to draw people from the private sector, but only one of four applicants was from the private sector. When Bebee was hired for a similar position nine years ago, he competed against 40 other applicants.

A 2018 Brookings Institution report notes the employment void exists even though water workforce occupations not only pay more on average compared to all occupations nationally, but also pay up to 50 percent more to workers at the lower ends of the income scale. In San Diego County, water and wastewater plant and systems operators are earning an average salary of $70,000 annually, according to the U.S. Bureau of Labor Statistics.

Skilled workers needed to operate increasingly complex systems

While the Bureau of Labor Statistics notes that fewer people may be needed in coming years as water and wastewater plants become more automated, a skilled workforce is required to operate increasingly complex controls and systems. Some of the most advanced facilities in the world are in Southern California, including the Claude “Bud” Lewis Carlsbad Desalination Plant, the naton’s largest desalination plant.

Local educational efforts in the industry are addressing the potential worker shortage:

  • Palomar College’s Water and Wastewater Technology programs, provides pre-employment training and advanced courses for people who want to become certified as a water or wastewater operator.
  • The Water Authority’s student internship program pays $12 an hour and has interns working at four different water agencies throughout the year.
  • California State University, San Marcos Certificate in Water Management & Leadership program is geared toward workers already employed as intermediate-level supervisors in the water industry and offers training and skills needed for higher management positions.
  • The Center for Water Studies at Cuyamaca College.

The Brookings report noted the glut of retirements offers an opportunity to diversify the industry. In January, the Center for Water Studies held the first in an annual series of Women in Water symposiums, attracting several hundred women and high school girls from throughout Southern California interested in a new career.

“Challenges can prompt people to get together and look at new ways of doing things,” said Greg Thomas, general manager at the Rincon del Diablo Municipal Water District in Escondido. “This is a great industry, it pays well, and you’re doing something good for people and society.”

New Permit Fosters Sustainable Water Production at Carlsbad Desalination Plant

San Diego regional water quality regulators today issued a permit for the installation of new, technologically advanced and environmentally sensitive seawater intake and discharge facilities at the Claude “Bud” Lewis Carlsbad Desalination Plant.

The plant – and the new permit – support Gov. Gavin Newsom’s April 29 executive order for California “to think differently and act boldly by developing a comprehensive strategy to build a climate-resilient water system.”

Under the new National Pollution Discharge Elimination System (NPDES) permit, the Carlsbad plant will continue producing about 50 million gallons a day of high-quality, drought-proof drinking water for the region as Poseidon Water and the San Diego County Water Authority develop a permanent, stand-alone seawater intake and associated structures.

Environmentally sensitive facility

The new intake-discharge system is needed for long-term operations of the nation’s largest seawater desalination plant, which started commercial production in December 2015 using water withdrawn from Agua Hedionda Lagoon for once-through cooling at the Encina Power Station. So far, it has produced more than 46 billion gallons of drinking water with reverse osmosis technology.

“The Carlsbad Desalination Plant is an invaluable asset for the state and region that helps us adapt to the changing climate and sustain a $231 billion regional economy,” said Jim Madaffer, chair of the Water Authority’s Board of Directors. “It is the most environmentally sensitive and technologically advanced plant of its kind in the nation – part of our commitment to collaborative projects and integrated water solutions for San Diego and the Southwest.”

Water supply sustainability

The closure of the power station in December 2018 led to temporary intake-discharge operations that will continue while new, stand-alone desal intake-discharge facilities are built. Conversion to stand-alone operations was anticipated in the 2012 Water Purchase Agreement between Poseidon, which owns and operates the desalination plant, and the Water Authority, which purchases the water for regional use. Currently, the plant provides about 10 percent of the region’s water supply.

“We are very thankful to the Regional Board for supporting the environmental enhancements of the Carlsbad project and water supply reliability for San Diego County,” said Poseidon CEO Carlos Riva. “This plant will continue to be a vital regional resource for decades to come and an example of how environmental stewardship can go hand-in-hand with water supply sustainability.”

Peter MacLaggan, senior vice president of project development with Poseidon Water, describes the water quality improvement at the Carlsbad Desalination Plant during a regional water quality control board public hearing in San Diego on May 8, 2019.

Transition in three phases

With the permit in hand, the transition to the new intake and discharge facilities will be implemented in three phases:

  • Temporary Operations – NRG, which owns Encina Power Station, continues to operate the water circulation pumps while an interim intake system is constructed.
  • Interim Operations – Expected to begin in mid-2020, this phase uses new fish-friendly pumps as a replacement for the existing circulation pumps. A new, permanent screened intake system also will be designed and built in the lagoon during this phase of operation. The new intake will rely on innovative technology, including 1 mm screens that will further enhance marine life protection.
  • Permanent Operations – The new submerged, screened-intake system is expected to be connected in late 2023, achieving the best available technology to minimize impacts to marine life in full compliance with the 2015 California Ocean Plan Amendment.

Once permanent operations begin, the Carlsbad Desalination Plant will be the first to comply with the 2015 Ocean Plan Amendment, designed to advance ocean water as a reliable supplement to traditional water supplies while protecting marine life and water quality.

Environmental stewardship

Poseidon is also protecting the coastal environment by taking over responsibility for the preservation of Agua Hedionda Lagoon from NRG. As the lagoon’s steward, Poseidon Water is taking responsibility for ensuring the man-made lagoon continues to realize the life-sustaining benefits of an open connection to the Pacific Ocean through periodic maintenance dredging.

Dredging keeps sand from blocking the flow of ocean water in and out of the lagoon, maintaining its tidal circulation, which is needed to maintain a healthy marine ecosystem, support extensive recreational uses, sustainable aquaculture at Carlsbad Aquafarm, and a white seabass hatchery operated by Hubbs-SeaWorld. Dredging also helps replenish the sand on Carlsbad State Beach, which otherwise would revert to historical cobble-stone, with sand that is relocated from the lagoon to nearby shoreline.

Temporary operations are anticipated to cost about $6.5 million annually, increasing the cost of water from the plant in 2020 by about $135 per acre-foot. Permanent facilities are projected to cost between $66 million and $83 million. The Water Authority is seeking state grant funds to defray some of that cost.

The Water Authority purchases up to 56,000 acre-feet of water from the Carlsbad plant per year – enough to serve approximately 400,000 people annually. The plant is a major component of the Water Authority’s multi-decade strategy to diversify the county’s water supply portfolio and minimize vulnerability to drought or other water supply emergencies.

Drones Offer Water Agencies Cost, Safety Benefits

Water agencies across San Diego County are saving time and money while improving employee safety with drones.

Industry analysts say drone use by water agencies worldwide is growing. The Helix Water District, Otay Water District and the San Diego County Water Authority have embraced the technology, using drones to inspect and monitor facilities, and to map and survey inaccessible areas.

Helix used a drone in February to check rooftop air vents on a water storage tank in El Cajon, rather than send employees high in the sky to do it. The agency determined it was too risky for employees – even with safety equipment – and too costly to have staff inspect the vents outside the 120-foot-high Fletcher Hills Combined Tank.

“We continually look for ways to utilize technologies where appropriate to minimize facility down time and to keep staff safe,” said Carlos Lugo, general manager at Helix. “Drone technology is proving to be a useful and cost-efficient way to survey and keep the district’s facilities properly maintained.”

Drones provide a safe and cost-effective alternative for inspecting the condition of storage tank vents without placing employees at risk or taking the storage tank offline. Photo: Helix Water District

Helix uses drones to inspect interior roof supports of its water storage tanks. The supports are especially vulnerable to corrosion because they are constantly exposed to humidity and heat.

Inspecting the storage tank roof supports requires moving 30-foot-high scaffolding from one support to the next, a time-consuming and labor-intensive process. To cut down that time, Helix used a drone to get high-resolution images of the supports. The drone images showed which ones needed repair without moving the scaffolding to each support.

“Using drones for this type of inspection work is a simple, elegant and safe solution,” said Jim Tomasulo, Helix’s director of engineering. “We anticipate using drones for this and other purposes.”

Drone inspections of reservoirs, treatment plant

The Otay Water District also is finding drones useful to save money and improve employee safety.

After a two-year study and evaluation period, the district is now using two camera-equipped drones to assist with preliminary inspections of its water facilities in eastern and southern San Diego County, including 40 potable water reservoirs, four recycled water reservoirs, 20 pump stations and a recycled water treatment plant.

Drones Reduce Risk

Countywide, the Water Authority uses drones to monitor rights of way and to survey inaccessible landscapes.

When a drone was used to get images and video of steep terrain on the Second Aqueduct west of Interstate 15 and south of the San Luis Rey River, the images were 10 times higher resolution than stock aerial images. Using the drone also kept staff from being exposed to potentially dangerous conditions.

The Water Authority is also exploring using drones for future surveys and potentially at water transportation, treatment, and storage facilities, where cutting-edge technology is used to save ratepayers money.

Drones are helping the Water Authority monitor rights of way, particularly in areas of rugged terrain.

But the potential of drone use is not limited to visual photography of elevated water tanks and surveying remote areas.  Water quality monitoring is another potential application.

Water agencies can use drones with infrared cameras “to monitor water areas remotely at higher spatial resolution than ever before, at low cost and at any time,” Michal Mazur, with Drone Powered Solutions, told Waterworld.com in a recent article about the advances in drone use.

San Diego Grown Photo Contest Highlights County’s Agricultural Bounty

The San Diego County Water Authority is hosting a social media photo contest during Water Awareness Month in May to celebrate how safe and reliable water supplies fuel the region’s local farms and food production.

The “San Diego Grown Photo Contest” on Instagram and Twitter highlights the significance of agriculture to the regional economy. As one of the nation’s top producers of avocados, ornamental trees and shrubs, flowers, succulents, lemons, and other agricultural products, San Diego County’s farms generate nearly $4.8 billion in total annual economic activity on some 250,000 acres.

The contest is part of the Water Authority’s ongoing Brought to You by Water outreach and education program, designed to convey the importance water supply reliability for sustaining the region’s 3.3 million people and its $231 billion economy. The Water Authority and its 24 member agencies work together to meet current and future water demands, while promoting water-use efficiency.

“Safe and reliable water supplies help more than 5,500 farms to thrive in our region – not to mention countless backyard gardens, community gardens and farmers markets,” said Jim Madaffer, chair of the Water Authority’s Board of Directors. “This photo contest offers everyone a chance to showcase their favorite locally grown fruits, vegetables, flowers and nursery plants, and to win some great prizes donated by sponsors who share our commitment to our region’s most precious natural resource.”

Agriculture: brought to you by water

The Water Authority is coordinating with the nonprofit local chapter of the Farm Bureau, which is supported solely by more than 2,000 dues-paying members. Established in 1914, it serves the needs of the San Diego agriculture community through a variety of advocacy and education initiatives.

“Farming is a foundational piece of our regional economy and quality of life – but it doesn’t happen without a reliable water supply,” said Eric Larson, executive director of the San Diego County Farm Bureau. “Our farmers are constantly innovating to use water more efficiently through adopting new technology and more-efficient crops.”

Reliable water supply helps drive regional economy
