California’s water recycling movement has evolved from experiments to expansion—driven by progressive regulations, proven technology, and positive public trust. In this episode, Traci Minamide, Greg Wetterau, and Roshanak Aflaki of CDM Smith share expert insights from decades of experience advancing reuse across the Golden State.

They reflect on the past, when early projects like the East Valley initiative faced setbacks and public skepticism that reshaped how engineers, utilities, and communicators approached outreach and transparency.

In the present, they highlight how clearer regulations, efficient treatment processes, and pilot projects have made large-scale water recycling both achievable and affordable—turning wastewater into safe, local drinking water for millions.

Looking to the future, the panel envisions a new generation of systems powered by AI-driven operations, advanced membranes, and rapid water-quality monitoring tools that will make direct potable reuse more widespread and resilient than ever before.

This episode is part of The Golden State of Reuse, a series exploring the past, present, and future of water recycling across California.

The series is a collaboration with WateReuse California and sponsored by CDM Smith.

The series is also supported by the Sacramento Area Sewer District, Black & Veatch, and Monterey One Water.
