California Drought Now in Third Year

/in , /by

California officials have urged residents to prepare for a third year of drought and urged people to conserve water.

“With only one month left in California’s wet season and no major storms in the forecast, Californians should plan for a third year of drought conditions,” said California Department of Water Resources Director Karla Nemeth. “A significantly below-average snowpack combined with already low reservoir levels make it critical that all Californians step up and conserve water every day to help the state meet the challenges of severe drought.”

The DWR conducted the third snow survey of the season March 1 at Phillips Station.

Following a January and February that will enter records as the driest documented in state history, the manual survey recorded 35 inches of snow depth and a snow water equivalent of 16 inches, which is 68% of average for this location for March, according to the DWR. The snow water equivalent measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast. Statewide, the snowpack is 63% of average for this date.

Water conservation “a way of life” in San Diego County

“As we enter a third year of drought, we encourage residents and businesses in San Diego County to increase their water conservation efforts,” said Jeff Stephenson, water resources manager with the San Diego County Water Authority. “While the Water Authority and its 24 member agencies have worked to create multiple sources of water supply for the region, there are still opportunities, including rebates, to save more water.”

In San Diego County, the website, watersmartsd.org, provides sources of residential and business rebates, including indoor and outdoor incentives, agricultural programs, and free landscape makeover classes.

Stephenson added that the region has reduced its reliance on imported water supplies, including from the Sacramento-San Joaquin Bay Delta, which means more of that source is available for other parts of California.

Governor Gavin Newsom has asked all Californians to cut back water use at least 15% compared to 2020 levels. Regionally, the Northern, Central, and Southern Sierra snowpacks are all standing just above 59% to 66% of average for this date, impacting watersheds across the state, according to the DWR.

“As the world continues to warm, precipitation is pushing toward extremes,” said Jeremy Hill, Manager of DWR’s Hydrology and Flood Operations Branch. “Even when we see large storms producing a lot of snow early in the season, all it takes is a few dry weeks to put us below average. This new pattern challenges forecasting efforts that have relied on historical patterns, so DWR has led the charge to adopt new technologies and utilize the best available science to manage water in real time and use forecasts that give us time to make decisions to get the most benefits and minimize the hazards.”

Dry times in the Golden State

Although early season storms helped alleviate some drought impacts, a lack of storms in January and February heightens the need for conservation. The Governor has asked all Californians to cut back water use at least 15 percent compared to 2020 levels. Regionally, the Northern, Central, and Southern Sierra snowpacks are all standing just above 59 percent to 66 percent of average for this date, impacting watersheds across the state.

“With below average precipitation and snowpack up until this point, our latest statewide snowmelt forecasts are only 66 percent of average,” said Sean de Guzman, Manager of DWR’s Snow Surveys and Water Supply Forecasting Unit. “That is not enough to fill up our reservoirs. Without any significant storms on the horizon, it’s safe to say we’ll end this year dry and extend this drought a third year.”

Proactive Pipeline Repair Maintains Water Supply Reliability, Affordability

/in , /by

The San Diego County Water Authority is proactively fixing a 90-inch diameter pipeline in Bonsall. The work is part of the agency’s long-term commitment to maintaining regional investments in water supply reliability and affordability.

Water Authority staff detected potential pipeline weaknesses just north of West Lilac Road in late January using real-time acoustic fiber-optic monitoring. This technology locates distressed sections of pipelines even while they are in use as part of the Water Authority’s high-tech asset management program.

Further investigation prompted the Water Authority to prioritize repairs on a 48-foot-long section of pipeline. Water Authority staff are carefully monitoring the pipe section around the clock while preparing designs and identifying contractors that can quickly mobilize for repairs.

Water supply affordability

Plans are to shut down and drain that stretch of pipe starting March 1. Work to replace the pipeline segments will continue until the line is back in service approximately 10 days later.

“This repair highlights the value of strategic investments in money-saving asset management tools and training,” said Martin Coghill, a senior manager for operations and maintenance at the Water Authority. “By proactively identifying this problem spot, we prevented what could have been a major unplanned shutdown.”

Coordination, collaboration with member agencies

The Water Authority has been coordinating closely with retail water agencies in North County that rely on deliveries from Pipeline 4. Rainbow Municipal Water District, Fallbrook Public Utility District, City of Oceanside, Valley Center Municipal Water District, and Vallecitos Water District are preparing to continue water deliveries by other means to homes and businesses while Pipeline 4 is out of service.

Fortunately, while Pipeline 4 is shut down the Water Authority’s resilient system can deliver treated water to retail agency connections from multiple sources, including the Carlsbad Desalination Plant.

Water Authority infrastructure repairs are funded by water ratepayers countywide. Regional investments in supply reliability ensure consistent and timely monitoring, maintenance, and repairs of the complex countywide water delivery system. Those investments, in turn, support San Diego’s regional economy and quality of life.

The Water Authority operates and maintains a water delivery system capable of delivering more than 900 million gallons of water per day through 310 miles of large-diameter pipeline, 1,600 aqueduct-related structures, and approximately 100 metering/flow control facilities. It also includes a state-of-the-art water treatment plant, hydroelectric facilities, pump stations, flow regulatory structures, and reservoirs that store water for emergencies and dry years.

Proactive asset management saves ratepayers money

As assets age, the Water Authority proactively replaces and repairs them to minimize impacts to member agencies and the public. Investments in the latest inspection technologies, including electromagnetic scanning, robotic inspections and 3D tunnel inspections help the Water Authority’s asset management team detect defects in pipelines and related facilities. By identifying corrosion or other types of deficiencies early, potential problems are corrected so they don’t become large and more costly issues.

Approximately 82 miles of the Water Authority’s pipelines are pre-stressed concrete cylinder pipes, also known as PCCP, that are made from a combination of steel and concrete. However, numerous catastrophic failures have occurred with these pipes worldwide in recent decades. In response, the Water Authority instituted a proactive program in 1991 to reinforce the pipelines with steel liners. To date, the Water Authority has relined 47 miles of PCCP.

Vista Irrigation District To Hold Public Hearings On Redistricting

/in , /by

Vista, Calif. – Vista Irrigation District board of directors will hold a public hearing on March 2, 2022 at 9 a.m. to discuss proposed adjustments to division boundaries as part of the decennial redistricting process.

Every ten years, agencies with by-district election systems, such as Vista Irrigation District, must use new federal census data to review and, if needed, redraw electoral division boundaries to reflect how local populations have changed. This process, called redistricting, ensures all electoral divisions comply with both the California and federal Voting Rights Acts. The District must reestablish electoral divisional boundaries, creating divisions that are balanced in population and in accordance with local, state, and federal laws that govern the redistricting process. Redistricting does not change the District’s service area boundaries.

Otay Water District Invests in Preventive System Maintenance

/in , /by

As part of its preventive maintenance program to safeguard its water supply and reduce water loss, the Otay Water District is conducting leak inspections of its pipeline system. Leak detection and repair programs save water by ensuring water system integrity. The District uses state-of-the-art equipment to inspect its water distribution system for leaks in pipelines, meters, and valves. The equipment is designed to “listen” for leaks and can pinpoint the location of even the smallest water leak. Once identified, crews will schedule the needed repairs.

Otay’s contractor, Utility Services Associates, will inspect approximately 173 miles of potable water mains in Rancho San Diego, El Cajon, and Jamul, along with potable and recycled water mains in areas of Chula Vista. The work is now underway.

Water leaks often account for a substantial portion of lost revenue in water utility systems. If just small single-digit percentages of water carried by the Otay Water District’s pipelines were lost to leaks, it would cost hundreds of thousands of dollars per year and waste a precious resource.

Otay Water District customers may see workers inspecting the meter in front of their home or business, typically between 7 a.m. and 5 p.m., Monday through Friday. Some weekend and night work may also be required. The duration of the inspection can range from a few minutes to one day.

Workers will be wearing a Utility Services Associates logo and carry company identification. They will not need access to customers’ homes or property but may contact customers if they need to momentarily shut off their water supply for further testing. They will not shut off the water supply without permission from someone at the home or property.

Workers may be lifting water meter covers, inspecting, and attaching equipment to meters or valves. If a leak is suspected, the Otay Water District will contact the customer and advise them of the potential leak.

The inspection has an estimated completion date of Friday, April 29, 2022, subject to weather and other circumstances.

Customers with questions on the Leak Detection Program can contact Otay Water District’s customer service representatives at (619) 670-2222.

San Vicente Potential Energy Storage Facility Project Moves Ahead

/in , /by

As partners, the City of San Diego and the San Diego County Water Authority will begin negotiations on a project development agreement with the BHE Kiewit Team to develop Phase 1 of the potential San Vicente Energy Storage Facility Project, which could generate enough energy for about 135,000 households.

The proposed project is subject to a full environmental review and regulatory approvals. If the Water Authority and City of San Diego decide to proceed after completing environmental review, the San Vicente Energy Storage Facility would provide up to 500 megawatts of long-duration stored energy upon completion to help meet peak electrical demands throughout Southern California and help meet California’s renewable energy goals.

“Reliable, clean source of energy”

“On top of providing a reliable, clean source of energy and helping our City and the state of California meet our climate goals, this project has the potential to create well-paying local jobs,” said San Diego Mayor Todd Gloria. “I’m proud of the City’s partnership on this project and look forward to it moving though the regulatory approval process to fruition.”

The Water Authority’s Board of Directors on January 27, approved entering into negotiations with BHE Kiewit, along with a $4.6 million contract with AECOM Technical Services, Inc. to perform environmental work for the project.

The Board also approved a $1.6 million amendment to a professional services contract with Black & Veatch Corp. to support project development agreement negotiations, provide technical expertise for a California Independent System Operator interconnection application, perform preliminary design and engineering reviews, and assist with preparing a Federal Energy Regulatory Commission (FERC) license application.

Water Authority Board Chair Gary Croucher said the Board’s action will help propel the potential project forward by getting started on environmental review and other necessary requirements.  “The San Vicente Energy Storage Facility Project meets multiple goals for the San Diego region, including protection from blackouts and supporting climate-friendly energy sources,” said Croucher. “We’re excited to get moving.”

Phase 1

Phase 1 work includes activities required to complete site investigations, design, and engineering; support state and federal environmental reviews; support the acquisition of a CAISO interconnection agreement; support the acquisition of a FERC license; and collaborate with project partners to achieve commercialization.

Four proposals were received and evaluated for the project development contract. Teams submitted written proposals followed by interviews in December. Evaluators considered each team’s understanding of the scope of work, technical and specialized qualifications, strategies to commercialize the project, and financial capabilities.

Pumped energy storage facility project

The panel unanimously recommended starting negotiations with the BHE Kiewit Team, which includes BHE Renewables, LLC, and Kiewit Development Company. BHE Renewables, LLC, is a wholly owned subsidiary of Berkshire Hathaway Energy Company. The Water Authority Board today also approved negotiating with Rye Development, LLC, if negotiations with the BHE Kiewit Team are not successful.

California sources nearly one-third of its power from renewables, mainly solar and wind. The target for renewable energy in California is 60% by 2030. Such a major shift to renewables will require new kinds of investments, markets and business practices. Electric grids need to be more flexible; new kinds of power supplies will help deliver energy flexibility when needed; and new pricing systems are needed to send clear signals to developers and financial markets that these projects need to move forward.

Pumped energy storage projects, such as the San Vicente Energy Storage Facility, are designed to store excess renewable energy from solar and wind during the day, and then discharge that energy when energy use increases in the evening and renewable energy is not as plentiful.

Energy Storage Process-San Vicente Energy Storage Facility-Renewable Energy

The San Diego County Water Authority and the City of San Diego are partners in developing the San Vicente Energy Storage Facility. The pumped storage energy project at San Vicente Reservoir could store 4,000 megawatt-hours per day of energy, or 500 megawatts of capacity for eight hours. Graphic: San Diego County Water Authority

The San Vicente project would create a small upper reservoir above the existing, City-owned San Vicente Reservoir, along with a tunnel system and an underground powerhouse to connect the two reservoirs. As planned, the powerhouse would contain four reversible pump turbines.

During off-peak periods – when power is inexpensive and renewable supplies from wind and solar facilities exceed demand – turbines would pump water to the upper reservoir where it would act as a battery of stored potential energy. During high energy use, the system would discharge water from the upper reservoir downhill through the turbines, producing energy. The exchange between the two reservoirs would not consume water.

San Vicente Reservoir is near major electricity transmission interconnection facilities, which would allow the project to play a central role in integrating solar and wind energy from across the Southwest for use in San Diego County.

The San Vicente project is largely immune to the challenges faced by some conventional hydropower facilities because it would rely on an existing reservoir that holds primarily imported water and does not fluctuate significantly from year to year.
