Every year, California faces a brutal cycle of wildfires, but this time, the stakes are higher than ever. The Palisades and Eaton Fires have destroyed over 12,000 homes, burned 40,000 acres, and displaced 100,000 people. But beyond the visible destruction, there’s another crisis unfolding—one that remains largely unseen: the failure of our water infrastructure.
In this episode of Liquid Assets, we sit down with Reuben Vollmer, CEO and Co-Founder of Spout Water, to discuss how California’s water mismanagement played a pivotal role in fueling these wildfires—and how it’s now impacting the drinking water of thousands. With fire hydrants running dry, plastic pipes melting into the water supply, and entire communities left with "do not drink" advisories, we explore the connection between fire, climate change, and water security.
Reuben shares his personal experience of being evacuated due to the fires and the devastating loss of not just homes but the memories tied to them. He explains how a decade in the water industry led him to develop Spout, an innovative device that pulls clean drinking water from the air, offering an alternative for those who can no longer rely on traditional water infrastructure.
We also dive into the controversial use of fire retardants—why they're necessary, but how they may also be accelerating the growth of invasive species, setting the stage for even bigger fires in the future. And, as bottled water shortages rise, Reuben unpacks why one in five Americans already rely on bottled water and what that means for our environment.

As the world grapples with an escalating water crisis, the need to rethink our approach to water management has never been more urgent. With approximately 75% of the world's wastewater going untreated, the implications for both the environment and human health are staggering. Urban areas, in particular, face unique challenges as population densities rise and climate change intensifies. In this context, the concept of urban water reuse emerges not just as a solution, but as a transformative opportunity to redefine our relationship with this vital resource.
In this episode of Liquid Assets, host Ravi Kurani engages in a thought-provoking conversation with Kyle Pickett, co-founder of the William J. Worthen Foundation. Together, they explore the innovative strategies and technologies that are reshaping urban water reuse, turning what was once considered a niche practice into a mainstream solution for sustainable living.
Kyle's journey into the world of water reuse began with a passion for sustainability and a desire to make complex water concepts accessible to everyone. He emphasizes that the future of water management lies in demystifying reclaimed water and breaking down the barriers that prevent communities from embracing it. The “yuck factor” often associated with recycled water can deter even the most environmentally conscious individuals. However, Kyle argues that education and transparency are key to overcoming these misconceptions. By showcasing successful projects, such as the Salesforce Tower in San Francisco, which saves over 7 million gallons of potable water annually, he illustrates how luxury developments can lead the way in sustainable practices.
Listeners will find themselves captivated by the discussions surrounding the integration of innovative technologies in water reuse systems. Kyle highlights the importance of advanced filtration and monitoring systems that ensure reclaimed water is safe and effective for various uses, from irrigation to toilet flushing. These technologies not only enhance the efficiency of water management but also contribute to a circular economy where water is treated as a valuable resource rather than a disposable commodity.
