In this episode Talking Under Water co-host Bob Crossen speaks with Krishna Prashanth, global product line manager for electromagnetic flow meters and global segment manager for water and wastewater instrumentation at ABB, about the promise and practicality of the circular water economy.
Prashanth explains how the concept shifts water management away from a linear take-treat-discharge model and toward a system focused on reducing losses, reusing water, recovering resources and extending the value of every drop. He outlines the “six Rs” — reduce, reuse, recycle, reclaim, recover and restore — and argues that utilities must evolve from operators of pipes and plants into stewards of local water loops.
The conversation also explores the critical role of data capture, monitoring and analysis in making circularity possible, from identifying leaks and managing demand to improving reuse decisions and predicting infrastructure issues. Prashanth and Crossen discuss how AI can strengthen these efforts when paired with trusted instrumentation, as well as the barriers standing in the way, including regulatory silos, misaligned incentives and aging infrastructure.
Together, they paint a picture of a more resilient, efficient and resource-aware future for water utilities.
