One Imperial Irrigation District director Tuesday afternoon pushed back on two solar projects, contending they would only provide a spike in the short term while the land would be more beneficial in the long term if used for agricultural purposes.
The Biden administration and Congress are stepping up efforts to control the release and cleanup of poly and perfluoroalkyl substances, or PFAS, in drinking water sources and elsewhere, joining states that have expanded scrutiny of the chemicals, which are used widely in manufacturing and are extremely persistent in the environment.
The San Diego County Water Authority’s Board of Directors April 22 authorized staff to explore opportunities to help other water districts weather an emerging drought across California.
Three decades of investments in supply reliability, along with a continued emphasis on water-use efficiency, mean the San Diego region has sufficient water supplies for multiple dry years. Those investments include high-priority conserved water from the Imperial Valley, seawater desalination, and access to the Semitropic Original Water Bank in Kern County, where the Water Authority has stored about 16,000 acre-feet of water.
The Board authorization allows Water Authority staff to assess selling, leasing, or swapping its Semitropic water with agencies that need it. Increasingly severe impacts of drought are already being felt in Central and Northern California. Any agreement recommended by staff would be brought to the Board for approval.
“Given the extraordinarily low 5% allocation on the State Water Project and the location of our groundwater in the Central Valley, it’s a perfect time to explore mutually beneficial agreements with agencies that need more water this year,” said Water Authority Board Chair Gary Croucher. “The Water Authority is committed to innovative ideas like this to improve water management across the arid West and at the same time benefit San Diego County ratepayers.”
This water supply and opportunity is available because in 2008 the Water Authority secured extra water for the San Diego region in preparation for future droughts. At the time, the Water Authority worked with the Metropolitan Water District of Southern California to swap that water for 16,000 acre-feet of MWD water stored in the Kern County water bank. Due to other water supply investments which have come on-line, the Water Authority has not needed to call on its Semitropic water.
Given its current water supply portfolio, Water Authority staff will look at the potential to use its stored water to help other agencies and generate revenues for the benefit of San Diego County ratepayers.
At the same time, the Water Authority continues to pursue authorization to store water supplies which are qualified for storage in Lake Mead, which is declining due to a two-decade drought in the Colorado River Basin. If the Water Authority could store water there, it would also open up the potential for other water management strategies to improve Lake Mead water levels and water supply reliability for the Basin States.
“It’s in everyone’s best interest to think creatively about long-term water management even though that will mean doing new things in new ways,” said Croucher. “A fresh, collaborative approach is our best hope to act as a multi-state region to meet the needs of people, farms and the environment.”
California is facing a second consecutive dry water year. Snowpack and precipitation are below average in both the Northern Sierra and the Upper Colorado River Basin, and most California reservoirs are below their historical averages for this time of year. On March 23, the California Department of Water Resources reduced the State Water Project allocation from 10% to 5%. The only other year on record with such a low SWP allocation is 2014. Following the state’s April 1 snow survey, DWR Director Karla Nemeth declared the state’s conditions “critically dry.”
Those circumstances highlight the importance of San Diego County’s supply diversification strategy that began after the drought of the early 1990s. Back then, the region was hit with 50% supply reductions because it relied almost entirely on one source. Since then, the region has added a significant new transfer of conserved agriculture water from the Imperial Valley, completed the All-American and Coachella Canal lining projects to receive conserved Colorado River water, invested in the Claude “Bud” Lewis Carlsbad Desalination Plant, and continued to embrace water-use-efficiency measures that have become a way of life in San Diego County.
The Water Authority’s draft 2020 Urban Water Management Plan shows that regional investments in a “water portfolio approach” to supply management and a sustained emphasis on water-use efficiency mean that San Diego County will continue to have sufficient water supplies through the 2045 planning horizon – so the region’s residents and economy remain safe even during multiple dry years.
April 23, 2021 – The San Diego County Water Authority’s Board of Directors yesterday authorized staff to explore opportunities to help other water districts weather an emerging drought across California.
Three decades of investments in supply reliability, along with a continued emphasis on water-use efficiency, mean the San Diego region has sufficient water supplies for multiple dry years. Those investments include high-priority conserved water from the Imperial Valley, seawater desalination, and access to the Semitropic Original Water Bank in Kern County, where the Water Authority has stored about 16,000 acre-feet of water.
April 22, 2021 – The San Diego County Water Authority and the Vallecitos Water District have reached agreement over pipeline repairs and how to measure water deliveries while moving ahead as partners to ensure long-term water supply reliability. The Water Authority’s Board of Directors on Thursday approved terms of a settlement with Vallecitos designed to end litigation filed in 2020. Vallecitos’ Board of Directors previously approved the terms.
In March, Water Authority staff judged water-related projects by students at the 67th annual Greater San Diego Science and Engineering Fair. Judging the fair is a longstanding tradition at the Water Authority and a component of the education outreach program. For decades, the Water Authority has recognized the top water-related projects with a scholarship and award. This year’s fair was conducted in a virtual format, but more than 280 students still brought their best projects to the table.
Each student who was interviewed by Water Authority staff demonstrated a strong knowledge of the scientific process, as well as an awareness of big picture issues that are important in the water industry and beyond. Five winners were selected, and each will receive a gift card and plaque. Water Authority staff also showcased a video of the five winners and their outstanding projects at the April San Diego County Water Authority Board of Directors meeting.
In the senior division, first place winner Bella Rose Schremmer designed a piston-buoy rack and pinion wave energy converter device. The 10th grader from University City High School said she was inspired by the kinetic energy formed by ocean waves, and she wanted to create a project that could capture that energy as a renewable energy source to replace the burning of fossil fuels. Bella Rose attributed part of her success in this project to her father, who supported her by procuring materials and providing encouragement, and to her teacher and mentor, Mrs. Bosch, who guided her through the process.
In second place, Suvali Sengupta created a biodegradable microporous polymer that was designed to help soil water retention in an agricultural setting. The 11th grader from Westview High School shared that her inspiration came from her Indian heritage and the drought conditions that India’s farmers struggle with each year.
In the junior division, Kristine Talaga from St. Gregory the Great Catholic School won first place with her project on saltwater desalination. The 7th grader designed a project to test the effects of different colored backgrounds – black, white or foil – on containers containing salt water and how quickly heat could desalinate the water in each container.
Samantha Rivera, an 8th grader from Chula Vista Middle School, claimed second place with her project about which methods of water purification removed the most dissolved solids.
In third place, 8th grader Sonria Rheiglene Simanski, also representing Chula Vista Middle School, tracked how much water is wasted when waiting for the shower to warm up, determining the best times of day to shower for optimal water-use efficiency.
Standing in the dry, cracked bottom of Lake Mendocino, Gov. Gavin Newsom declared a drought emergency Wednesday in two Northern California counties where grape growers and wineries are major users, an order that came in response to arid conditions affecting much of the state and the U.S. West.
The declaration is targeted to Mendocino and Sonoma counties, where drought conditions are especially bad, rather than statewide, as some officials and farmers in the agricultural-rich Central Valley had hoped. But the Democratic governor said a broader drought declaration could come as conditions change.
San Diego County residents who have converted to more water-efficient landscaping can enter the 2021 WaterSmart Landscape Contest hosted by 12 regional water agencies. Entry is as simple as submitting your photos and plant information by Friday, May 14. Eleven San Diego County Water Authority member agencies are participating, including the Helix Water District, Otay Water District, and Sweetwater Authority.
The Ramona Municipal Water District has unveiled a new mobile phone app that allows customers to view and pay bills and to review details of their account, including their water consumption history.
(Editor’s note: The Ramona Municipal District is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)
As spring temperatures rise, San Diego County residents know wildfire season is not far behind. Although wildfire is a serious threat during warm, dry summer and fall months, wildfire can strike year-round especially in wildland interface areas. Regional landscaping must follow fire safe guidelines in design, plant selection and consistent maintenance
