Possible Water Board hearing on desalination plant is nearing – California

Those supporting Poseidon Water’s plans to build a saltwater-to-freshwater conversion factory on the Huntington Beach coast certainly hoped the desalination project would be moving forward in earnest by now.

A December 2019 vote on the desalination plant was put off, however, and Poseidon would have to wait a few more months before knowing whether it would be allowed to go forward with its ambitious $1 billion project.

Members of the Santa Ana Regional Water Quality Control Board are expected to make a decision on Poseidon’s project in April. Will the board finally approve the permits Poseidon has been seeking for several years?

New solar-powered system makes desalination ecofriendly – America

A completely passive solar-powered desalination system developed by researchers at Massachusetts Institute of Technology (MIT) and in China could provide more than 1.5 gallons of fresh drinking water per hour for every square metre of solar collecting area. 

Such systems could potentially serve off-grid arid coastal areas to provide an efficient, low-cost water source, said MIT doctoral students in a paper appearing in the journal ‘Energy and Environmental Science’.

The key to the system’s efficiency lies in the way it uses each of the multiple stages to desalinate the water. At each stage, heat released by the previous stage is harnessed instead of wasted. In this way, the team’s demonstration device can achieve an overall efficiency of 385 percent in converting the energy of sunlight into the energy of water evaporation.

Why desalination can help quench California’s water needs – California

If you’ve ever created a personal budget, you know that assigning your money to different investment strategies is a crucial component to meet your financial goals.

When you stop dipping into your savings account each month, savings can begin to build.  

Understanding why desalination is so critical to California’s water future is a lot like building a personal budget. With a changing climate, growing population and booming economy, we need to include desalination in the water supply equation to help make up an imported water deficit.

Chile seawater desalination to grow 156% – Chile

Cochilco analyst Camila Montes said desalination use would grow most in the drier northern parts of the country, forecasting 65% usage in Antofagasta, 60% in Tarapaca, 42% in Atacama and 25% in Coquimbo.

Some 90% of the desalinated seawater will be used in the processing of copper sulphide ores for the production of copper concentrates.

The addition of seawater desalination to a large-scale project adds at least a billion dollars to project capex, up to over $3 billion for a massive plant such as the 2,500 litres per second (lps) plant BHP added at Escondida in 2018.

Desalination Plant Can Transform Monterey Peninsula And Help Avert Water Crisis – California

Nobody likes to look out to the Pacific Ocean and see oil derricks on the horizon. That’s why California wisely banned new offshore oil drilling 50 years ago.

But in Monterey County, coastal views are limited by a relic of a bygone era: a giant, industrial sand plant right on the dunes between Highway One and the ocean.

In 2017, the California Coastal Commission reached an agreement with the sand plant for operations to shut down by 2020 and for all buildings and equipment to be removed by 2023.

Composites’ role in seawater reverse osmosis desalination – California

In an effort to solve water shortage issues in the U.S. state of California, Governor Gavin Newsom has ordered key state agencies to develop a blueprint for meeting California’s 21st century water needs, to ensure safe and resilient water supplies, flood protection and healthy waterways for the state’s communities, economy and environment.

Two solutions in which composites play a significant role are wastewater purification (which was featured in CW‘s January 2020 feature “Composites help take the waste out of wastewater”) and, the focus of this report, seawater reverse osmosis (SWRO) desalination.

The problem in California is easy to understand, but difficult to solve: The original configuration of rivers, streams, lakes, bays and underground water (aquifers) in California has been reconfigured so extensively over the years to accommodate a growing population and conflicting interests that these resources cannot be relied upon to meet future water needs — even the near future.

Water Authority Offers to Settle Long-Running Rate Dispute with MWD – California

The San Diego County Water Authority’s board offered Thursday to settle a long-running dispute over rates with the giant Metropolitan Water District of Southern California.

The offer, made following a special board meeting, asks MWD to make $140 million in payments to San Diego County water customers to cover claims from 2011 through 2020 and, in the future, follow new, transparent procedures in setting water rates.

“The Water Authority’s proposal would benefit residents across San Diego County, enhance understanding of how MWD’s rates are set, and provide more opportunities for our agencies to collaborate in ways that would benefit water management across the Southwest,” said Water Authority Board Chair Jim Madaffer.

Huntington Beach desalination plant eyes approval, but foes turn out in force – California

With Poseidon Water’s plans for a Huntington Beach desalination plant approaching the homestretch, critics were as adamant as ever at a Friday workshop, where dozens complained the proposal is environmentally flawed, unneeded and would jack up water rates.

The meeting of the Santa Ana Regional Water Quality Control Board was called to review a draft permit and solicit public comment in advance of a scheduled April 3 vote on the final permit.

Approval rides on whether the board determines the drought-proof project will “use the best available site, design, technology and mitigation measures feasible to minimize the intake and mortality of all forms of marine life.”

Residents to have their say on Belmont desalination plant – New York

The Department of Planning, Industry and Environment is asking for community feedback on an application by Hunter Water for a drought response desalination plant at Belmont.

Executive Director, Infrastructure Assessments, David Gainsford, said community input is a vital part of the planning process and encouraged everyone to have their say on the draft proposal.

“Hunter Water has lodged a State Significant Infrastructure application for a desalination plant at Belmont which could be used to supplement the Lower Hunter’s water supplies during times of extreme drought,” Mr Gainsford said.

EIR for desal project approved – United States

Ocean water desalination, in which salt and other compounds would be removed from water in the Pacific and introduced into the water supply for drinking and other potential uses, could have numerous potential benefits, West Basin said, including “reducing reliance on imported water, improving water security through increased local control of water supplies,” and “improving climate resiliency” by providing a water source that is not dependent on the shifting volume of rain and snow that arrives each year.

Opponents, however, have said that the project poses significant environmental issues. The desalination process is energy-intensive, even more so than carrying imported water hundreds of miles from other parts of the state.

And it also arrives as alternatives for enhancing the water supply, many of them focused around water recycling and which are less energy-intensive, are becoming more widespread.
