More than 70% of the Earth’s surface is covered in water, but only 0.5% it is actually accessible to us. Removing salt from ocean water, known as desalination, can create drinkable water during a time of extreme drought and soaring demand. So what’s the problem?
As California enters a third dry year, the Bay Area’s biggest water agency, the East Bay Municipal Utility District, may soon push forward with strict caps on customer water use, and fines for those who exceed the limit.
The agency, like most water suppliers in the region, has been relying only on modest outdoor watering restrictions, and voluntary conservation, to reduce consumption. But with lackluster savings and a continuing water shortage, the district’s governing board is scheduled to decide next week whether more aggressive rules are necessary.
In a California forest torched by wildfire last summer, researcher Anne Nolin examines a handful of the season’s remaining snow, now darkened by black specks from the burned trees above.
Spring heat waves had already melted much of the year’s limited snowfall across California and parts of the West when Nolin visited in early April. But she and her colleague are studying another factor that might’ve made the snow vanish faster in the central Sierra Nevada — the scorched trees, which no longer provide much shade and are shedding flecks of carbon.
The Colorado River’s 1,450-mile run begins amid the snowy pinnacles of the Rocky Mountains and ends in the subtropical waters of the Gulf of California. Over the millions of years the river has been running this course, it has gradually carved through the Southwest’s crimson limestone and shale to create a succession of unimaginably vast canyons: Ruby, Cataract, Marble, and Grand. The writer Marc Reisner described the Colorado as the “American Nile.” The Hualapai call it Hakataya, “the backbone.”
California is heading into its third year of drought after record dry stretches.
One of the biggest losses the state saw in the 2022 water year was the lack of rain and snow during the typically wet January to March time frame. Historically, December through March are the wettest months for the state. The past three years have come up short for precipitation leading to water restrictions and bigger conservation efforts.
California utility San Diego Gas & Electricity (SDG&E) has released new projections for meeting California’s decarbonization goals. The study, The Path to Net Zero: A Decarbonization Roadmap for California, predicts that in order to reach the mandated carbon neutrality by 2045, the state will need to quadruple its electricity generating capacity from 85 GW to 365 GW, add 40 GW of energy storage, and integrate 20 GW of green hydrogen – while also adding 4 GW of fossil gas with carbon capture and sequestration technology.
The utility said that they believe a mix of resources will be needed to “maintain electricity system reliability in the SDG&E service area” as total consumption increases by an estimated 100%, and peak demand grows by 85%.
The Rainbow Municipal Water District board approved a financing agreement for a group of planned capital projects.
The March 22 board vote authorized Rainbow general manager Tom Kennedy to execute a financing agreement with Western Alliance Business Trust for $9,750,000. The financing will have a 3.55% interest rate and will be repaid over a 20-year period.
Third-generation San Joaquin Valley farmer Gary Beene will plant only half his 1,200 acres this year. He doesn’t have enough water for the other half.
“We’re working on survival more than anything else and getting through this year,” said Beene, who farms tomato, almond, cotton and garlic with his sons and grandson on the land his grandfather settled in California in the 1930s after sharecropping in Oklahoma. “It’s pretty discouraging. I’m hoping to steer my grandchildren away from agriculture. It’s sad.”
Encinitas, Calif. — Olivenhain Municipal Water District’s Board of Directors unanimously approved today the filing of a notice of completion for the Manchester Avenue Potable Water Pipeline Project. Pipeline replacement work is now complete along Manchester Avenue, Rancho Santa Fe Road, and Encinitas Boulevard. In total, 3,700 linear feet of aged potable water pipeline was replaced.
The pipelines previously serving water in this area were installed in 1961 and were approaching the end of their lifespan. OMWD takes a proactive approach in repairing and replacing aging water infrastructure to avoid leaks and ensure the continuation of uninterrupted water service to its customers. As the impact of California’s drought continues to escalate, projects like this that help save potable water are even more urgent.
Conserving water and reducing pollution are two of many benefits from a new program in San Diego County.
Through a partnership between the County of San Diego’s Watershed Protection Program and the San Diego County Water Authority, residences and businesses in unincorporated areas of the county became eligible for newly enhanced water-use efficiency rebates in 2021. The Waterscape Rebate Program saves money for residential, commercial, and agricultural customers who make landscape upgrades to improve the region’s climate resilience and reduce the flow of pollutants into waterways.
The new concierge-style assistance program helped members of a Spring Valley homeowners association benefit from available incentives and rebates. As a result, residents saved money on landscape upgrades while reducing the flow of pollution into waterways and conserving water.

To make applying for rebates easier for large landscapes, the county added a Landscape Optimization Service, a unique technical assistance program for large-scale landscaping projects. The program helps applicants with large landscapes, such as HOAs and commercial properties, navigate the requirements, overcome barriers, and maximize their rebate eligibility.
LOS staff analyzes estimated water and cost savings, which details how quickly the project will pay for itself. The program also offers discounted designs to participants.
The finished project is estimated to reduce water use by almost two million gallons annually. Their total project costs prior to the rebate were approximately $120,000. After the rebates, the HOA paid just $13,000 for the project. Photo: Courtesy Rancho San Diego Association
“Many of our larger customers, such as HOAs, are run by volunteers who don’t have the time or resources to undertake large landscape projects,” said Joni German, Water Resources Specialist at the Water Authority. “Most of their landscapes were put in during the 1970s, and many are ready for a water-efficient upgrade. This partnership with the County enables us to offer HOA customers a first-of-its-kind program with assistance from start to finish.”

The project is estimated to reduce water use by almost two million gallons annually. Total costs prior to the rebate were estimated at $120,000. After rebates, the HOA paid $13,000 for the project.
Currently, seven San Diego County HOAs are working through the process of removing common area grass with the support of County of San Diego contractor Environmental Incentives.
The project is estimated to reduce water use by almost two million gallons annually. The total project costs prior to the rebate were approximately $120,000. After rebates, the HOA paid $13,000 for the project.
“The County is proud to partner with HOAs, like the Rancho San Diego Association, to help protect local waterways by transitioning to a more sustainable landscape,” said Scott Norris, Land Use Environmental Planning Manager with the County Water Protection Program. “We look forward to expanding the Landscape Optimization Service in the coming years to assist more properties in upgrading their outdoor space and helping protect water quality.”
Sustainable landscapes produce multiple benefits, which include reducing water use, enhancing habitat, increasing stormwater retention, and decreasing runoff.
The enhanced incentives include rebates starting at $3 per square foot for turf replacement, $60 per smart controller station, $65 per rain barrel, and up to $450 per cistern. In addition to offering technical assistance to upgrade larger landscapes on multifamily and commercial properties, a cost-share is available for agricultural growers to make water-saving upgrades.
Water customers in unincorporated San Diego County can determine their eligibility at SanDiegoCounty.gov/WatershedRebates. The Landscape Optimization Service is actively recruiting new participants.
The Waterscape Rebate Program helps to protect local waterways by reducing pollutants that enter storm drains. When irrigation systems overflow from landscaping, runoff may carry pollutants like pesticides, herbicides, and fertilizers into the storm drain system and cause the same adverse effects as runoff from rainfall. Reducing turf helps reduce irrigation use and runoff.
The program includes outreach and education to commercial, industrial, and residential properties in unincorporated areas of the county. San Diego County is also offering programs with rebates for upgrades, including rain gardens, gutters, permeable pavement, and regular septic system pumping.
(Editor’s note: The Helix Water District and Otay Water District are two of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)
