A long-sought compromise has been approved that will open the stagnant, reed-filled Buena Vista Lagoon to the sea and restore its native coastal marine habitat, but years of work remain before the transformation begins.
Santa Barbara’s Water Outlook Foresees Sufficient Supply to Meet Demands Through Fall 2022 – California
The city’s water-supply forecasting shows there’s sufficient supply to meet demands through fall 2022, while allowing groundwater basins to slowly recover and rest, water supply analyst Dakota Corey told the city’s Water Commission at Thursday’s special meeting.
The availability of water from Gibraltar Reservoir, upstream on the Santa Ynez River, in the past few years as well as Santa Barbara’s desalination plant operation and water conservation have enabled the city to accumulate a significant amount of stored water in Lake Cachuma, Corey said.
Online-Only Public Comment for Poseidon Desalination Plant Public Hearing Draws Criticism – California
A state regional water board is drawing public criticism in Orange County for holding meetings on a controversial desalination plant in Huntington Beach, while public participation can only be done virtually amid the coronavirus health crisis.
The Santa Ana Regional Quality Control Board is meeting this morning to hold a public hearing on Poseidon Water’s request for a permit renewal for their facility, which would be built on 12 acres of a power plant and produce 50 million gallons of water per day, according to water district staff.
The project has remained controversial for years over what critics say will be drastic environmental damage and increased water rates. The approval process for Poseidon Water’s proposal has been marked by legal disputes, permit crusades and lobbying campaigns paid for by the company.
Researchers analyzed how the use of solar power could increase the competitiveness of electrochemical approaches such as electrocoagulation (EC), capacitive deionization (CDI), electrodialysis (ED) and electrodeionization (EDI).
The four methods examined, according to the scientists, are not as capital-intensive as traditional large-scale water treatment centers, while also being modular, portable and energy efficient. The use of solar could also make smaller electrochemical facilities suitable for desalination of brackish water in remote regions.
This is the claim of Guoliang “Greg” Liu, an assistant professor in the Department of Chemistry at Virginia Tech who has conducted extensive research into the design and synthesis of porous carbon fibres. The material is composed of long, fibrous strands of carbon with uniform mesopores of approximately 10nm.
According to Virginia Tech, Liu sees the primary application of his porous carbon fibres in the automotive industry, where similar materials are used as the external shells of some luxury cars. Now, Liu reports capacitive desalination as a new application for this material.
“Because of the high surface area of the porous carbon fibres, we can store a lot of ions,” Liu said in a statement. “Because of the interconnected porous network, the ion movement is very fast inside the pores.”
US officials have questioned a China-tied company’s bid to construct a new desalination plant in Israel and have expressed concerns over the possibility of it winning the tender, Axios reported Saturday.
Hutchison Water International is one of two companies to have reached the final stage of the tender to build the Sorek B plant, set to be the largest desalination facility in the world, alongside IDE Technologies.
On April 28, with support from the National Renewable Energy Laboratory (NREL), the U.S. Department of Energy (DOE) kicked off the Solar Desalination Prize, a $9 million competition that’s part of the American-Made Challenges series.
If the directors approve the new voting system next year, SCWD would join the hundreds of other public agencies to move away from at-large voting under threat of lawsuits authorized by the California Voting Rights Act.
In January, SCWD received a demand letter from Newport Beach attorney Philip Greer who claims to represent a number of SCWD ratepayers concerned that at-large elections stymie candidates who represent the district’s racial and socio-economic diversity. District leaders immediately signaled their acquiescence to avoid a costly lawsuit.
