After a third straight year of severe drought, the Bureau of Reclamation’s Central Valley Project begins the 2023 water year with 3.6 million acre-feet of water in storage — one of the lowest starting points in recent years. The CVP’s major reservoirs are (from north to south) Trinity, Shasta, Folsom, New Melones, Millerton, and the federal share of San Luis Reservoir. The water year begins Oct. 1 each year and ends Sept. 30.
As part of its study of new water supplies, the Marin Municipal Water District is planning a public workshop later this month to review how it will rate and compare the various options it is considering.
The online meeting at 5 p.m. Oct. 25 will provide an opportunity for the public to ask questions of district staff and its consultants who are drafting the water supply report.
October 13, 2022 – Sections of the regional aqueducts will be shut down over the next six months for maintenance projects to ensure a safe and reliable water supply for the region. The San Diego County Water Authority and its member agencies are coordinating on the annual “shutdown season” to minimize impacts to residents and businesses, who are not expected to face service disruptions.
Sections of the regional aqueducts in San Diego County will be shut down over the next six months for maintenance projects to ensure a safe and reliable water supply for the region. The San Diego County Water Authority and its member agencies are coordinating on the annual “shutdown season” to minimize impacts to residents and businesses, who are not expected to face service disruptions.
Starting October 16, a portion of Pipeline 5 will be out of service for 10 days to accommodate annual maintenance on the entire untreated water system and to prepare for rehabilitation of other sections of the pipeline. The Water Authority has worked for months to coordinate with the affected retail water agencies: Olivenhain Municipal Water District, San Dieguito Water District, Santa Fe Irrigation District, Helix Water District, Sweetwater Authority, and the cities of San Diego, Oceanside, Ramona, Poway and Escondido. Customers should check with their water utility if they have questions about localized impacts.
The Pipeline 5 work will rehabilitate about 5,000 feet of 96-inch diameter prestressed concrete cylinder pipe by inserting and securing a steel pipe liner. This portion of the pipeline is within the City of San Marcos, between North Twin Oaks Valley Road and the Water Authority’s Twin Oaks Water Treatment Plant. When completed, approximately 50 miles, or 61% of the Water Authority’s existing prestressed concrete cylinder pipe will be relined.
“Proactive asset management and coordination with our member agencies ensures that the region’s major water infrastructure reliably serves the region’s 3.3 million residents,” said Eva Plajzer, the Water Authority’s director of operations and maintenance. “We have worked with our member agencies for several months to minimize any impacts to residents and businesses.”
The Water Authority’s Asset Management Program is a key element of providing safe and reliable water supplies to the region. The agency continually assesses and inspects its 310 miles of large-diameter pipelines, which provide treated and untreated water to 24 member agencies in San Diego County. The program is widely recognized for pioneering work – including a patented inspection device – that promotes water affordability by avoiding costly unplanned disruptions in service. Maintenance work is scheduled during low-demand periods to minimize impacts on water service.
Constructed in 1982, Pipeline 5 is a vital component of the Water Authority’s regional water infrastructure system, delivering untreated supplies from Lake Skinner in southwest Riverside County to the Lower Otay Water Treatment Plant in southern San Diego County.
In addition to the October upgrades on Pipeline 5, a series of three shutdowns on the Water Authority’s First Aqueduct is scheduled from December through April, when portions of the aqueduct will be relined, along with other maintenance.
(Editor’s note: The Olivenhain Municipal Water District, San Dieguito Water District, Santa Fe Irrigation District, Helix Water District, Sweetwater Authority, and the cities of San Diego, Oceanside, Ramona, Poway and Escondido are 10 of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)
Water managers are preparing for a warm winter, a worse drought and a chance of biblical floods. As California discovered last year, the weather can swing wildly from one extreme to the next each month—offering little reliability for farmers planting winter crops or planning for the next irrigation season.
Conditions are lining up for a rare third year of La Niña, which tends to bring heavier precipitation to the Pacific Northwest and drier weather to most of California. Last year two atmospheric rivers delivered the bulk of the water supply in October and December, with total precipitation adding up to 76% of average for the water year that ended last month. But the last two winters have demonstrated that an adequate snowpack can disappear in just weeks under spring heat waves.
One of the largest public works projects in Sacramento’s history has been quietly under construction, out of sight for most people in the region.
Sacramento RegionalSan is upgrading its wastewater processing facility in Elk Grove, which processes wastewater from customers across Sacramento County, and West Sacramento in Yolo County. On an average day, 150 million gallons of wastewater is handled at the facility.
With Oct. 1 marking the beginning of a new water year, Mendocino County officials reported recently that local water districts are preparing for what could be another dry year.
In the latest update from the Mendocino County Water Agency, local water managers are quoted as describing their current status and outlook.
The National Weather Service in Seattle posted a graphic this week that contains a startling fact. Since July 1, Seattle, a city synonymous with rain, has been drier than San Diego, a city synonymous with clear, dry skies.
From July 1 to Oct. 9, San Diego recorded 0.65 inches of rain. Seattle, 1,250 miles to the north, had only 0.48 inches.
California American Water has shifted its plans for a desalination plant on the shores of Marina, announcing it will now seek to build the project in multiple phases.
“Phasing the Monterey Peninsula Water Supply Project strikes the right balance to meet the critical need for sufficient and reliable drought-proof water supply to meet demands in the near term while allowing for additional supply as it becomes needed over the next 30 years,” said Josh Stratton, a Cal Am spokesman, in an email. “In addition, as we heard from the community, phasing the project with the possibility of expanding the project to accommodate future regional water supply needs through public participation is important. This is a win-win for the region that provides an opportunity to help the Monterey Peninsula Water Supply Project be part of future water supply solutions for our customers and nearby communities.”
On Scott Beylik’s 4-acre farm about 60 miles northwest of Los Angeles, rows of tomato vines climb wires strung from the beams of his greenhouses. There’s no soil, so the roots are submerged in little bags with water. Every drop of water he uses goes directly to the plant.
s the drought in the West drags on, the future of water-loving crops like tomatoes hangs in the balance. Hydroponic farming — the technique Beylik farms with — uses as little as 10% of the water traditional systems use to grow tomatoes and other field crops.
