Arizona: Desalination without a Coastline? – USA

 In Israel, for example, five massive desalination plants on the shores of the Mediterranean Sea produce nearly a half-million acre feet of fresh water per year, an amount the nation plans to double by 2030. Israel’s Sorek Desalination Plant, located a few miles south of Tel Aviv, produces 185,000 acre feet of fresh water per year, from a highly automated operation that occupies only about 25 acres. Approximately 80 percent of Israel’s municipal water comes from desalination, and this nation of 9 million people is now exporting surplus water to Jordan.

Now is the time to secure Arizona’s water future – United States

Arizona is doing a lot of things well. Our economy is growing and diversifying at one of the fastest rates in the nation.

We recovered jobs lost during the pandemic before almost any other state, and unemployment has fallen to its lowest rate in nearly 50 years.

Businesses and new residents are moving here in droves to take advantage of the pro-growth policies we’ve adopted to make Arizona one of the most competitive and attractive places in the country to invest, expand and create jobs.

Ducey desalination proposal carries hefty price tag – Arizona

This Friday marks Earth Day. This year the drought and dwindling water supplies top the list of environmental challenges here in the southwest.

Scientists remain at odds over Gov. Doug Ducey’s plan to help solve Arizona’s water issues by desalinating water from the Sea of Cortez.

Ducey unveiled the idea in his State of the State address earlier this year. He proposed a $1 billion project to draw treated water to Morelos Dam near Yuma, but the challenges to the idea remain difficult to solve.

ASU MAY HAVE A KEY ROLE IN ARIZONA’S $1B WATER INVESTMENT – United States

Arizona’s water future is unclear, but ASU is working to change that. Existing programs and schools at the University focusing on research and development could be key in finding the best set of solutions to the state’s water crisis.

The dual threat of increased population and megadrought conditions due to climate change are not likely to ease in the near future.

Drought conditions that have persisted in the West are considered to be the driest 22-year period since the year 800, a report from Nature Climate Change […]

Arizona Gov. Calls for $1B Desalination Plant – United States

Arizona Gov. Doug Ducey’s announcement this week that he would work with the Legislature to provide $1 billion to “secure Arizona’s water future for the next 100 years” focused entirely on a new desalination plant in Mexico.

But a funding plan for the plant that was a key part of Ducey’s final state of the state address isn’t on the table right now.

In fact there’s no clear plan for when such a plant might come to be, two key advisors to the Republican governor said Wednesday.

Pima County Considers Building Costly Desalination Plant – Arizona

That’s how a Pima County, Ariz., official, Eric Wieduwilt, describes a new proposal for a $4.1 billion desalination project that would start with a plant to remove salt from seawater in the Sea of Cortez in Sonora.

Then, the water would be shipped 196 miles by underground pipeline to the Tucson area, says a county study of the project.

The cost could add up to $60 to $90 per month to the typical Tucson-area homeowner’s water bill, said the County Regional Wastewater Reclamation Department’s study.

UA developing efficient system to purify waste water – Arizona

Using a grant of $500,000, the team of researchers is developing a solar-powered desalination system that combines several types of technologies to recover water from these concentrated waste streams.

The grant comes from the Department of Energy’s Rapid Advancement in Process Intensification Deployment.

The process uses less energy at a lower cost, and it could provide more water for resource-scarce inland regions such as Arizona.

Major southwestern city water supplies – Colorado

For Phoenix, it’s water is supplied through surface water sources. The northern end of the city gets water from the Central Arizona Project, which is supplied by the Colorado River and Lake Mead. The southern end gets its water from the Salt River Project.

Las Vegas gets 90% of its water from the Colorado River and Lake Mead and 10% from groundwater sources. The groundwater supplies up to 25% during the hot summer months when demand is high. In 1971 Las Vegas with a population of […]

Nuclear Operators Scramble To Make Reactors Flexible Enough For New Energy Economy – Arizona – USA

Arizona Public Service is studying the possibility of using excess energy from its Palo Verde Nuclear Power Plant, when solar energy is flooding the grid, to desalinate brackish water.

In Illinois, Exelon is looking at repurposing a reactor to produce hydrogen when there’s plenty of wind energy on the grid, then using the hydrogen for steelmaking, ammonia production or fuel-cell vehicles.

Across the country, nuclear operators are trying to figure out whether they can ramp down their reactors, which are optimized to run at maximum capacity, during those hours or seasons when renewable energy is abundant.
