Splashes in a sewer trigger chain reactions that utilities battle every day. Hydrogen sulfide begins in the slime layer of sewer pipes — but when fast-moving flow splashes or drops, that disturbance releases the gas into the air, where it becomes odorous, corrosive, and dangerous. Understanding this splash-activated chemistry is…
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…
Meaningful community engagement starts with one simple step: listening. Crystal Davis of the National Parks Conservation Association says that real collaboration requires more than meetings and checkboxes — it demands accountability, non-extractive partnerships, and centering lived experience from the very beginning. Her message is clear: communities know what they need,…
Water isn’t just a natural resource in the Midwest—it’s the connector between education, health, opportunity, and community identity.

She also highlights major advances on the horizon…
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…
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…
Imagine using algae to clean wastewater and also grow fertilizer, boost crop yields, and even power airplanes. That’s the breakthrough behind Gross-Wen Technologies, where algae replaces chemicals—removing nitrogen and phosphorus while creating a valuable biomass for turf, agriculture, and even sustainable aviation fuel. Martin Gross explains how this circular approach…
California’s next leap in water recycling is all about precision, efficiency, and smarter treatment. Greg Wetterau of CDM Smith explains how engineers are pushing beyond traditional indirect potable reuse—testing new approaches that make direct potable reuse safer, more reliable, and far more affordable. From the Metropolitan Water District of Southern…
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…
Public trust nearly derailed one of California’s most important water recycling projects — but it also transformed how the state approaches reuse. Traci Minamide of CDM Smith explains how the East Valley project became a flashpoint in the early 2000s, when “toilet-to-tap” politics stalled progress for two decades. Today, that…
What should we rethink about water? Henk Ovink says we need to rethink how little attention we pay to the hydrological cycle — and how much of it depends on healthy land. Half of all rainfall on land comes from forests, wetlands, and other natural systems through transpiration. His message…
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,…
Federal funding for water infrastructure hangs in the balance. Adam Krantz of the National Association of Clean Water Agencies explains how the White House budget proposal nearly zeroed out key State Revolving Funds—dropping billions in investment to mere millions. Now, the House and Senate will debate how much to restore,…
America’s economic ambitions depend on water. From data centers and chipmakers to manufacturing and energy, every facility need a strong water foundation. Adam Krantz of the National Association of Clean Water Agencies says it’s time Congress and the White House connect the dots—investing in water infrastructure isn’t just about clean…
With D.C. often defined by political noise, water leaders are staying focused on what’s real. Adam Krantz of the National Association of Clean Water Agencies says his organization tunes out the screaming and symbolism in Washington by focusing on tangible progress—advocating for policies, tracking legislation, building bipartisan relationships. Amid political…
Clean 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…
What if the future of water infrastructure isn’t just massive treatment plants and tunnels — but also thousands of small-scale systems spread across our communities? That’s the vision driving Cynthia Koehler and the WaterNow Alliance. From green stormwater infrastructure and urban trees to water-efficient fixtures and turf replacement, these distributed…
Could one program finally bring order to America’s stormwater chaos? 🌧️ Jay Holtz of Oldcastle Infrastructure explains how the new STEPP Program — Stormwater Testing and Evaluation for Products and Practices — aims to create a unified national system for verifying stormwater technologies and approaches. By standardizing testing and ensuring…
Why does every city seem to have its own stormwater rules? 🌧️ Jay Holtz of Oldcastle Infrastructure explains how the EPA set broad national guidelines but left the details up to local agencies — leading to thousands of unique programs shaped by climate, soil, and regional priorities. The result is…
