Fires in and around Los Angeles continue to rage as gusting Santa Ana winds drive the flames through brush and into neighborhoods. Two major blazes, the Eaton Fire and the Palisades Fire, have combined burned almost 40,000 acres since last week. Another fire, the Auto Fire, erupted Monday evening in Ventura County. The fires have killed at least 24 people.
A study led by researchers at the University of North Carolina at Chapel Hill offers a solution to water scarcity during droughts amid the tug of economic development, population growth and climate uncertainty for water users in Western U.S. states. The proposed two-way leasing contracts would coordinate agricultural-to-urban leasing during periods of drought and urban-to-agricultural leasing during wet periods, benefiting both urban and agricultural water users.
Water reuse stands at the intersection of technology, policy, and public trust. The journey from basic agricultural reuse to advanced potable applications highlights the adaptability and potential of this approach.
Water scarcity and quality issues have increasingly pushed the boundaries of traditional water management practices. Among the innovative solutions gaining traction is water reuse, a concept that has evolved from agricultural and industrial applications to potable water supply. To explore the evolution, policy advancements, technological readiness, and future trends in water reuse in the United States, Smart Water Magazine spoke with three leading experts: Ben Glickstein, Director of Communications at WaterReuse Association; Eva Steinle-Darling, PhD, Water Reuse Technical Practice Director at Carollo Engineers; and Peter Grevatt, PhD, Chief Executive Officer of The Water Research Foundation.
From Ancient Greek sailors boiling seawater to Romans using clay pipes to filter salt, making saltwater drinkable through desalination has a long history. But modern forms of this millennia-old technology are now the “present and future of coping with water scarcity,” said Manzoor Qadir, deputy director of the United Nations University Institute for Water, Environment and Health.
The price of water is rising across the Southwest as utilities look to cover the cost of the increasingly scarce resource, the infrastructure to treat and distribute it and the search for new supplies.
For eight days last summer, a group of about 80 California ranchers and farmers took more than half the Shasta River’s flow during severe drought conditions, violating state requirements designed to protect salmon. The state’s water regulator couldn’t stop the illegal diversion but fined the group the maximum penalty it could — $4,000. The fine translated to about $50 per person.
There’s a water contradiction in the West with serious long-term water scarcity in low reservoirs and depleting groundwater tables, while California is in the middle of an extremely wet and snowy winter. As water levels in dangerously depleted Lake Mead and Lake Powell drop to record lows, California has experienced one of the wettest winters on record, with a statewide snowpack that’s almost 200 percent of normal for this time of year and a flooding risks from rain and snow events in March.
An almost limitless supply of fresh water exists in the form of water vapor above Earth’s oceans, yet remains untapped, researchers said. A new study from the University of Illinois Urbana-Champaign is the first to suggest an investment in new infrastructure capable of harvesting oceanic water vapor as a solution to limited supplies of fresh water in various locations around the world.
Each morning for months, Amelia Morán Ceja has peered out her window, searching Sonoma’s wine country for dark clouds or the residue of rain on the leaves of her grapevines.
Her searching has proved futile, and now she’s worried as California faces its third consecutive summer with drought.
The dry conditions threaten her thirsty vines at Ceja Vineyards and elevate the risk from fire and heat waves. The triple threat is a “perfect storm during harvest,” she said.
On the heels of the driest ever start to the year in California, Gov. Gavin Newsom on Monday issued a sweeping executive order calling on local water suppliers to implement more aggressive conservation measures as reservoirs dwindle and residents backslide in their efforts to cut back.
Specifically, the order requires that urban water suppliers activate “Level 2″ of their locally customized contingency plans, meaning they must prepare for a shortage of up to 20%.
