Where does our water come from? The real meaning of “Water Awareness Month”

By proclamation of the Governor in 2008, it is Water Awareness Month in Arizona.

So, what do you suppose that means?

On a personal level, being “water aware” almost universally means learning to conserve water. It is a precious and scarce resource, after all. As citizens of an arid Western state who are approaching our 17th consecutive year of drought, water conservation is an imperative.

As the British used to say during the grim days of World War II, we all need to “do our bit.”

In a “Water Awareness Month” promotion in the lobby of the Arizona Department of Water Resources building, state employees offered plenty of suggestions for conserving.

Taking shorter showers is good. So is avoiding over-watering plants, fixing leaky faucets and toilets and collecting rainwater in old-fashioned barrels.

But while conservation indisputably is a big part of “water awareness,” that’s not all it means.

It also means being aware of the nature of water in our arid environment. It means reaching beyond the kitchen faucet.

Only when we understand and appreciate the sources of our vital liquid resource can we truly claim to be water “aware.” Making wise choices as water consumers is important, but making wise water choices as a society is just as important. Maybe more so.

Perhaps the most important water-conservation choice Arizonans ever made as a society came about in 1980 when the state Legislature approved the Arizona Groundwater Management Act, which placed strict regulatory limitations on groundwater pumping in Arizona’s most populous regions.

That Act, as well as other legislation governing groundwater use enacted in subsequent years, is credited with making the difference between the genuine, drought-inspired crisis that California recently endured, and the comparative ease with which Arizona has managed to navigate its own much-longer period of drought.

In 1980, Arizona’s elected leaders clearly were water aware.

Today, water awareness includes having at least a rough appreciation for our state’s sources of water.

How many of us, for example, know that the largest portion of our water supply doesn’t even originate in Arizona?

Forty-one percent of Arizona’s annual supply – on average 912.4 billion gallons per year – begins its existence as snowpack on the Western slopes of the Rocky Mountains, eventually flowing into the Colorado River system through countless tributaries that become hundreds of streams, then dozens of rivers before rushing into the single, mighty and vital Colorado.

Another 16 percent of our supply, meanwhile, arrives at the kitchen spigot via the complex capture of in-state surface-water sources, notably the Salt River Project’s system of dams and reservoirs along the Salt and Verde rivers.

Arizona still gets 40 percent of its water supply from its underground aquifers – so-called “mined” groundwater. Just three percent, meanwhile, comes to us through reclaimed sources, although that percentage has risen sharply in recent years.

And tomorrow’s sources? Gov. Doug Ducey’s Water Augmentation Council is researching the prospects of adding new supplies, including desalination projects that could rehabilitate brackish water or even tap into salt-water sources off the coast of Mexico or southern California.

The governor’s council is… aware of every option. As citizens of the arid West, we all should be too.

Water Resources director hails agreement to expand uses of CAP canal system

“System-use agreement” between Central Arizona Project and the federal Bureau of Reclamation a major milestone for vital water-delivery system

Central Arizona Project and the federal Bureau of Reclamation reached an historic agreement on Thursday that allows for “new and innovative” uses of the CAP’s 336-mile system of canals, including transporting new water supplies, exchanging supplies among users and efficiently accessing water stored underground by the Arizona Water Banking Authority and others.

The agreement creates a legal framework for a variety of water supplies to be moved through the system, including many dedicated to addressing possible future shortfalls in Arizona’s Colorado River water allocations.

“It allows for flexibility in managing our Colorado River water supplies,” said Tom Buschatzke, director of the Arizona Department of Water Resources.

Until now, so-called “non-CAP water” – that is, water controlled by users other than the Central Arizona Project – flowed through the elaborate delivery system only on an ad hoc basis.  In 2014, for example, the cities of Phoenix and Tucson reached an agreement allowing Phoenix to store some of its unused Colorado River allocation in Tucson-area aquifers.

Thursday’s agreement provides a legal framework for such water exchanges, thus opening the door for further innovation, as well as for future agreements on water quality and financial issues.

CAP General Manager Ted Cooke also noted the additional flexibility that the agreement provides his agency. Cooke thanked the agencies involved in helping make it happen for their collaborative efforts:

“This agreement provides us with the flexibility for cost-effective recovery of stored water, including more than four million acre-feet of CAP water stored in the aquifers of central and southern Arizona,” said Cooke.

“I would like to thank the negotiators from the Department of the Interior and the Bureau of Reclamation, along with the significant contributions from the Arizona Department of Water Resources and the Arizona Water Banking Authority.”

Water Resources Director Buschatzke joined Cooke in extending thanks to the Arizona congressional delegation – especially noting the efforts of Arizona Senator Jeff Flake – for helping make the system use agreement happen.

“Our role was to support efforts to complete the system use agreement for the benefit of Arizona water users,” added Buschatzke.

“We sought to support the maximum flexibility of this important asset.”

Gov. Doug Ducey expressed thanks to former Interior Secretary Sally Jewell for her efforts in support of the system-use agreement.

The CAP canal system was built by the federal Bureau of Reclamation for the state of Arizona and is managed and operated by the Central Arizona Project.

The deal is especially valuable to the Water Bank, which pays to bring Colorado River water through the CAP system into central and southern Arizona. The Water Bank stores that water in underground aquifers, or directly recharges it into underground storage facilities. It also arranges for water deliveries to irrigation districts, which use the water in lieu of mined groundwater.

Water Bank officials helped review the agreement.

The deal creates a legal framework allowing the Water Bank to use the CAP system to make recovered water available during potential periods of shortage of Colorado River water deliveries to Arizona. Until now, the Water Bank’s capacity to make use of the water it stores has been extremely limited.
