In this episode Talking Under Water co-host Mandy Crispin speaks with Pranjali Kumar, associate vice president at Carollo and the firm’s Southeast Water Reuse Lead, about why the industry needs to look beyond treatment technologies and public perception when evaluating reuse projects.

Kumar explains how water reuse is increasingly being considered a resilience and sustainability tool rather than simply a drought response measure. She highlights the importance of systems thinking, organizational collaboration, and investment in human capital to ensure successful project implementation. The conversation also explores common misconceptions about potable reuse regulations, including the lengthy and collaborative process required to develop state-specific frameworks that protect public health while enabling innovation.

The discussion covers the factors that separate successful projects from those that stall, the economic realities of potable reuse compared to alternative water supply options, and the safeguards that make reuse a highly regulated and reliable source of drinking water. Looking ahead, Kumar shares insights on PFAS monitoring, artificial intelligence, advanced monitoring technologies, and how the next generation of water reuse leaders can build on lessons learned while remaining adaptable to change.
