Arizona’s high water authority is mulling a plan to pump water from a desalination plant by the Sea of Cortez, in a bid to reduce the state’s reliance on the Colorado River.

The plan, pitched by Israeli water remedy firm IDE Applied sciences, would contain a binational effort led by Arizona and the Mexican state of Sonora to construct the desalination plant and canals to pump water into Arizona and two Sonoran cities.

Arizona’s Water Infrastructure Finance Authority this week resolved to maneuver forward with the nascent plan, which nonetheless has to clear regulatory hurdles on the state, native and federal ranges in each Mexico and america.

If constructed, the desalination plant could be positioned on the Sea of Cortez coast close to Puerto Peñasco, a resort city on the Sonoran panhandle that’s lengthy attracted Arizonan tourism.

The primary canal from the plant would shoot north by way of Organ Pipe Cactus Nationwide Monument towards Arizona’s primary inhabitants heart surrounding Phoenix, in response to a report by AZ Central.

A secondary route would pump water south from the plant to Hermosillo, Sonora’s capital, and a 3rd canal or pipeline stemming from the principle line would ship water to the border metropolis of Nogales, Sonora.

The plan would provide as much as 1 million acre ft of water for buy to Arizona, in response to the IDE pitch. One acre foot is roughly the quantity of water essential to offer water to 2 households for one 12 months.

Arizona’s fast-growing inhabitants has contributed to water shortages within the Southwest, because the overtaxed Colorado River struggles to produce its seven basin states and Mexico.

The Colorado River stopped reaching the ocean often within the Sixties, after completion of the Glen Canyon Dam. Within the spring of 2014, U.S. and Mexican authorities launched a “pulse stream” of water resulting from earthquake harm to a Mexican irrigation system, permitting the river to succeed in its pure vacation spot for a couple of weeks.

However local weather change and inhabitants progress have elevated stress on the river, forcing Southwestern states to search for different sources of water.

Nonetheless, the desalination undertaking may face robust regulatory hurdles, partially due to its environmental influence.

Constructing by way of the Organ Pipe Nationwide Monument is one problem, as is the difficulty of disposing of the concentrated brine that’s a pure byproduct of desalination. 

And in response to the AZ Central report, the undertaking may face political headwinds, because it competes with different conservation and infrastructure initiatives for a $1.4 billion tranche put aside for the water disaster by outgoing Gov. Doug Ducey.

Whereas Arizona’s water choices are restricted, political opposition to a desalination undertaking may be flamed by the excessive relative price of desalinated seawater.
