What if the real game-changer in green infrastructure isn't adding more plants, but engineering the soil itself to become a pollutant-trapping powerhouse? Christian Hennessy of Oldcastle Infrastructure says the science of media development—fine-tuning soil matrices, depths, and materials—has been key to evolving from basic solutions to modern systems that deliver…
As new contaminants like PFAS demand complex treatment, many utilities face a hard reality: innovative solutions often stall at the regulatory desk. That bottleneck — not a lack of technology — is what Anthony DeRosa is working to fix. As Executive Director of the Association of State Drinking Water Administrators,…
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…
The water sector can’t fully serve communities if it doesn’t reflect them — and for too long, people of color have been underrepresented across the industry. That lack of representation creates trust gaps, reinforces barriers, and signals to many young professionals that they don’t belong. That’s the challenge Patricia Lindsay-Harvey,…
Clean water in national parks isn’t protected by accident — it’s defended by policy and by confronting the pressures outside park boundaries. Ed Stierli of the National Parks Conservation Association says that safeguarding these waters means not only upholding strong laws like the Clean Water Act, but also tackling the…
America’s national parks don’t just protect landscapes — they safeguard some of the most important waters in the country, from the Great Lakes and the Chesapeake Bay to the Colorado River, the Everglades, and even 10% of the nation’s coastline. These places give millions of people a chance to fish,…
Protecting America’s national parks has never been a passive job — and for more than a century, citizens themselves have stepped up to defend the waters, wildlife, and landscapes that define these iconic places. The National Parks Conservation Association was created in 1919 to be that independent voice, and today…
What if you could spot a failing motor or gearbox long before it breaks? Utilities are making that a reality by turning to smart sensor technology that tracks vibration, temperature, and performance around the clock. The power isn’t just in real-time warnings — it’s in long-term trending data that reveals…
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…
Cleaning water depends on nonstop power behind the scenes — and every pump, motor, and ditch in a wastewater plant has to run 24/7 to keep communities safe. The real challenge? Managing massive, constant energy demand while still delivering reliable treatment. Dave Zimmerman of Dodge Industrial explains how smarter mechanical…
Along California’s coast, protecting groundwater from seawater means knowing exactly what’s happening beneath the surface. Denver Grant of the Soquel Creek Water District explains how the team uses 84 coastal monitoring wells to track groundwater quality and watch for signs of seawater intrusion. By sampling for chlorides, total dissolved solids,…
Along California’s coast, saltwater intrusion can permanently contaminate groundwater—creeping inland as basins are pumped faster than they recharge. Melanie Mow Schumacher of Soquel Creek Water District explains how the community built a solution: sending treated wastewater four miles to an advanced purification facility, then another four miles to seawater-intrusion prevention…
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…
In the Salinas Valley, polluted agricultural drainage doesn’t have to flow straight into the river. Alison Imamura of Monterey One Water explains how the utility captures tile-drain runoff from thousands of acres—right before it reaches the Salinas River—and brings it into their recycling system. To make that possible, the team…
Water laws in the U.S. simply don’t reflect the true value of water — not to our health, our economy, our culture, or our communities. That’s the challenge Alexandra Campbell Ferrari is determined to fix. Through the Center for Water Security & Cooperation, Alexandra works with state legislators and utilities…
Pebble Beach was an early adopter of irrigating entire golf courses with recycled water—not just fairways, but tees and greens as well. Nick Becker of the Pebble Beach Community Services District explains how the district confronted salt buildup in the soils and invested in advanced treatment so the system could…
Around the world, artists and communities are proving that storytelling can spark climate action. As a Watson Fellow, Amy Spencer Harff of Imagine Earth Collective spent a year learning how creativity can shift mindsets, empower local leaders, and lead to real solutions. Her biggest takeaway: even in a hard moment,…
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, Allison Imamura of Monterey One Water, and Melanie Mow Schumacher of Soquel…
Every state in America is grappling with the same urgent mission: ensuring clean, safe, and affordable water for their communities. That’s where Ben Grumbles and the Environmental Council of the States are focused. As the national nonprofit that brings together all 50 state environmental secretaries, ECOS helps leaders educate, collaborate,…
Most Americans turn on a tap without a second thought — but in Navajo Nation, one in three families still live without running water. For generations, households have hauled every gallon they drink, cook with, and bathe in. But a quiet transformation is underway. Nonprofit DigDeep is bringing clean, reliable,…
In a time when diversity, equity, and inclusion initiatives are being rolled back across government and other sectors, Crystal Davis of the National Parks Conservation Association says the responsibility to protect equitable access to nature now falls even more on advocates and nonprofit leaders. She stresses that too many communities…
Communities are quietly upgrading one of the most overlooked parts of infrastructure: manholes. New composite materials and corrosion-resistant stainless steel are helping municipalities dramatically extend the life of their sewer structures—avoiding costly replacements and improving system reliability. As Kerry Koressel of IPEX explains, these upgrades are part of a broader…
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…
