In Sacramento, the shift to viewing wastewater as a critical resource is transforming regional water security and ecological health.

In this episode, Christoph Dobson, General Manager of Sacramento Area Sewer District, explains how the landmark $1.7 billion EchoWater project has elevated treatment standards to tertiary levels, protecting the sensitive Bay Delta while creating a massive new supply of recycled water.

This advanced infr...

Is the Chesapeake Bay finally turning a corner, or is restoration falling behind on its most critical deadlines?

This episode provides an expert "check-up" on America’s largest estuary with Hilary Falk, President and CEO of the Chesapeake Bay Foundation (CBF). After decades of investment, the results are a complex mix of record-breaking successes and urgent new challenges.

Explore the "Oyster Revolution"—a massive effort that has res...

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 highl...

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 be...

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 plan...

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...

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 ...

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...

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 ...

Communities across the Midwest are navigating a complex mix of water challenges—from affordability to agricultural pollution to protecting iconic national parks—and the policies shaping those outcomes.

In this episode, Crystal Davis, Senior Midwest Regional Director for the National Parks Conservation Association, discusses how regional advocacy, coalition building, and community-driven organizing are advancing solutions across 11 ...

Odor control and overflow prevention are critical yet often overlooked challenges for wastewater utilities — especially as urban areas expand and climate impacts intensify.

In this episode of Inside Infrastructure, Ryan Powers of the Wager Company explains how a family company that started in marine ventilation is now helping communities solve complex sewer problems on land.

He discusses why traditional chemical and carbon-based sys...

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 ...

Water’s future depends on sustainable funding, bipartisan policy, and stronger public communication.

In this conversation from the Reservoir Center in Washington, D.C., Adam Krantz of the National Association of Clean Water Agencies (NACWA) explains how federal investments and advocacy are shaping the next chapter for America’s water infrastructure.

He outlines the historic impact of the Bipartisan Infrastructure Law and why perman...

Across the U.S., stormwater regulations form a confusing patchwork that slows innovation and complicates compliance for communities and companies alike.

In this episode from WEFTEC, Jay Holtz of Oldcastle Infrastructure explains how this fragmented system has evolved — and why it’s time for change. He outlines the challenges posed by thousands of differing local approvals that make it costly and inefficient for solution providers t...

Activated carbon is a frontline solution in the fight against PFAS and other contaminants in water.

In this episode, Brandon Hamilton of Norit explains how activated carbon works like a “rigid sponge” —using its complex pore structures to trap everything from volatile organics to microscopic chemicals.

He breaks down why utilities are increasingly choosing activated carbon over reverse osmosis or ion exchange, highlighting its cost...

Los Angeles is turning recycled water into real-world resilience—protecting aquifers from seawater intrusion, powering industry, gaining public support, and building a next-generation supply that reduces dependence on imported sources.

At Terminal Island, Dean Taylor explains how this pioneering facility evolved from discharging into the harbor to producing advanced treated water that now feeds the Dominguez Gap seawater barrier and...

Utilities across the country are facing shifting water quality challenges — from changing influent chemistry to tightening discharge limits. This demands smarter monitoring and faster response.

In this episode, Carlos Williams of Hach shares how utilities are adapting to this evolving landscape through advanced analysis and real-time data.
