When Autumn Peltier was eight, she learned the tap water on a neighbouring reserve wasn’t safe to drink, or even to use for hand-washing. That injustice triggered her decade-long advocacy campaign for safe drinking water. She made headlines as a 12 year-old, admonishing Prime Minister Justin Trudeau at an Assembly of First Nations event for the choices his government had made for her people.

In this bonus episode for World Water Day 2023, Peltier and Jay discuss the way her life shifted, as she started campaigning for clean water. Peltier also shares what it was like to shoot her documentary The Water Walker, and lets us in on her plans for the future now that she’s finished high school.

On a day devoted to improving the way we manage, consume, and use water, the message is ‘Be The Change’ – something Peltier takes to heart. Two billion people still live without clean water, and the United Nations says member countries have fallen behind on their goal to bring everyone safe water and sanitation by the year 2030.

“The message is so much more powerful and so much more stronger when it's coming from a young person,” said Peltier, the chief water commissioner for the Anishinabek Nation. “That's when you know something is wrong, and something has to be done.”

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.
