A group of top water experts is challenging one of the core assumptions behind U.S. drinking water policy—that chasing ever-smaller traces of contaminants is the best way to protect public health—and instead calling for a fundamental shift toward fixing pipes, strengthening systems, and prioritizing the risks that actually matter most. In this episode, members of the Water Health Advisory Council lay out a bold path forward through their new book Safe Drinking Water Act: The Next Fifty Years. ...

Estuaries—places where rivers meet the ocean—are some of the most important ecosystems in the United States, supporting coastal economies, protecting communities, and serving as nurseries for much of the nation’s seafood. In this episode from the Reservoir Center in Washington, D.C., Daniel Hayden, CEO of Restore America\'s Estuaries, explains why these places—from Chesapeake Bay to Puget Sound – are essential to nature, the economy, and people. Hayden highlights collaborative restoration effo...

Water is emerging as a defining factor in U.S. economic growth and national security—from where data centers and energy projects can scale to how communities absorb the rising costs of floods, droughts, and insurance risk.

Explosive growth in data centers, semiconductors, and power generation is driving unprecedented industrial water demand, pushing reuse from niche to necessity across the U.S. In this episode, Bruno Pigott of the WateReuse Association, Courtney Tripp of Grundfos, and Jim Oliver of Black & Veatch unpack their joint report, Accelerating Industrial Reuse, spotlighting proven and sustainable strategies to meet that demand. They highlight how existing technologies enable up to 75–90% water savings t...

What happens when laws designed to protect water fail — and what legal action does it take to set things right? For decades, the health of the Chesapeake Bay has struggled because of three major pollution sources: stormwater, wastewater, and agriculture. These pressures send nitrogen, phosphorus, and sediment into streams and rivers that flow into the Bay, where they harm water quality and the environment broadly. While there have been many solutions implemented and tremendous progress made ac...

Green infrastructure is reshaping how communities manage stormwater by blending natural processes with modern engineering to improve water quality, reduce flooding, and fit into increasingly dense urban spaces. In this episode, Christian Hennessy of Oldcastle Infrastructure breaks down what makes a system truly “green,” from mimicking pre-development hydrology to using engineered soils, media amendments, and carefully selected plants to target pollutants like nutrients and metals. He covers ho...

Water is at the heart of America’s national parks, yet many of these rivers, lakes, coasts, and wetlands are under growing stress from pollution, climate impacts, and decisions made outside park boundaries. In this episode from the Reservoir Center in Washington, D.C., Ed Stierli of the National Parks Conservation Association explains how his organization serves as the independent voice for 433 national park sites, backed by nearly 2 million members. He breaks down why more than half of waterwa...

Wastewater treatment plants rely on nonstop mechanical power to keep water moving, oxygen flowing, and critical equipment turning—and the systems behind that power are the focus of this episode. Dave Zimmerman of Dodge Industrial breaks down how gearboxes, bearings, motors, and couplings form the “powertrain” that drives nearly every major process in a treatment plant. Zimmerman explains how these components support pumps, aeration basins, clarifiers, bar screens, screw conveyors, and oxidatio...

California’s Central Coast is turning recycled water into a lifeline for rivers, golf courses, farms, and coastal communities—showing how reuse can work far beyond the big cities. In this episode, Nick Becker of Pebble Beach Community Services District, Alison Imamura of Monterey One Water, and Melanie Mow Schumacher of Soquel Creek Water District share how their communities are rethinking every drop. At Pebble Beach, Becker explains how drought in the 1980s pushed local leaders to build one o...

Hydrogen sulfide is the invisible gas quietly eating away at sewer systems—driving odor complaints aboveground and concrete failure below. In this episode of Inside Infrastructure, Kerry Koressel of IPEX explains how H₂S forms inside collection systems, why splashing and drops inside manholes turn it into a corrosive, dangerous gas, and how it can silently destroy manholes, pipes, and metal components over time. He breaks down the real costs for municipalities, from emergency repairs and bypass...
