What About Water? with Jay Famiglietti

People in the lower Colorado River basin are now witnessing drastic cuts to their allotments. In many cases, developers find alternate sources of water by drilling into underground aquifers. But in places like Pinal County, Arizona, that groundwater is already becoming scarce. We hear from Stephen Q. Miller, who sits on both the Pinal County Board of Supervisors and the board for the Central Arizona Pipeline. Without sufficient water for crops, and facing some of the highest temperatures on record, he says farmers in his area will fallow up to 70 per cent of their land this year.

As Phoenix and its outlying suburbs start limiting development because of water shortages, those who stay put rely increasingly on wells and groundwater.

Arizona State University professor Kathryn Sorensen explains why consuming water from deeper wells is one solution – but it’s not ideal. The ancient freshwater underneath much of Arizona will never be replenished during our lifetimes. With high-tech cloud computing centers and some of the world’s biggest microchip manufacturers expanding their reach — and water use — we look at the desert future of the southwest.

With increasing water scarcity across the lower Colorado River basin states, we look at the technology of the future – and the role of cloud computing centers. How much water do they consume, and what does that mean for people in water-stressed areas? Amazon Web Services has set a goal to become water-positive by the year 2030, and we hear how the company is recycling and re-using water, with Will Hewes, AWS’ Global Lead on Water Sustainability.

Outside Phoenix, Intel Corporation has been a presence for more than four decades, with two recent expansions of its 700-acre campus in the desert. Those expansions allow Intel to manufacture more of the microchips that we rely on in modern life, powering everything from cell phones to automobiles. We hear from Intel vice-president and chief sustainability officer Todd Brady. He says the public-private partnership Intel struck years ago with the city of Chandler, AZ means a more sustainable, predictable supply of recycled water.

Water scarcity is also having a profound effect on the desert south’s political landscape. In this episode, we hear from Kathleen Ferris, a senior research fellow at ASU’s Kyl Center for Water Policy, and we check in with Patrick Adams, water policy advisor to Arizona Governor Katie Hobbs.

Our last word in this episode goes to the University of Arizona’s Kathy Jacobs, director of the Center for Climate Adaptation Science and Solutions.

Can we really “tech” our way out of freshwater shortages, scarcity, and pollution?

In our Season 4 finale, we’re asking the big question of the season – will new water technology be enough to solve wicked water problems? Will Sarni joins Jay for a look back at the bright ideas and inventions we’ve heard about this year, sharing his view on technology’s ability to solve problems around water quality and scarcity.

Jay and Will discuss what a “disruptor” like Uber could do for the water sector and what it will take to get the public sector to respond to innovation. And if you’ve ever wondered why piping water from a wet part of the country to areas hit by drought is a hot-button issue, you’ll want to stick around for our last ‘Ask Jay’ segment of the season.

Will Sarni is the CEO of Water Foundry and the founder and general partner of Water Foundry Ventures, a technology venture fund focused on addressing water scarcity, quality and equitable access to water. Will is a podcaster, an internationally recognized thought leader on water strategy and innovation, and the author of numerous books. You can check out his children’s book, Water, I Wonder here.

In this episode, we’re going underground, undersea and into your water and sewer pipelines with science fiction’s favorite problem-solvers...robots!

Jay sits down with Vanessa Speight, a professor of Integrated Water Systems at the University of Sheffield, to learn how new, spider-like robots have the potential to locate and fix leaks in aging water pipes.

Jay and Vanessa discuss when we might actually see these pipe-traveling bots in action and what they can realistically do for developing nations, where drinking water loss can be as much as 70 per cent due to aging and unmaintained systems.

In our Last Word, professor Lucian Busoniu tells us about SeaClear, a project funded by the European Union, building the first fleet of autonomous robots to collect litter from the ocean floor.

On this episode of What About Water? an entrepreneur in Austin, Texas turns his dishwasher sensor into a tech startup that’s feeding water utilities snapshots of their water quality in real time.

Jay sits down with Seyi Fabode, the CEO and co-founder of Varuna, to discuss how his company’s cloud-based software is helping cities keep track of their drinking water quality by the minute, allowing them to respond to spills, contamination, and fluctuations before it’s too late.

Jay and Seyi dream up a new tech idea together and trace Seyi’s entrepreneurial roots from his childhood in Nigeria to his post-grad in the UK. They discuss the $100,000 investment from the Google for Startups Black Founder Fund that opened new doors for Varuna, and what needs to change to get more black-owned businesses like Seyi’s off the ground.

At the end of the episode Jay answers a few questions about the Tri-State Water Wars and water privatization from our listener Mark, who’s based in Atlanta, Georgia.

How can we measure water when it disappears into thin air?

On this episode of What About Water? we’re looking at evapotranspiration, or “ET” for short. It’s the combination of water evaporating from the soil, combined with the measure of water transpiring through crops’ leaves. Accounting for this water loss helps farmers know exactly how much water they should apply across their fields, and new agricultural technologies and satellites are making it much easier.

Jay sits down with California State University at Monterrey Bay Senior Research Scientist – and former student – A.J. Purdy, whose doctoral thesis looked at the advancement and applications of satellite-derived ET algorithms.

We also hear what this looks like in real life, with Brett Baker, a sixth-generation California pear farmer and lawyer. With the ever-present risk of flood on his family’s land in the Sacramento-San Joaquin River Delta, Baker explains how OpenET is helping farmers like him and his father take better measurements of consumptive use.

Robyn Grimm, Interim Director of OpenET, tells us how this open-source platform is making big waves.
