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…
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…
Can you destroy PFAS and reuse your carbon at the same time? 🔥 Brandon Hamilton of NORIT explains how their reactivation process hits 1700°F for up to six hours, ensuring PFAS molecules are destroyed while restoring 80–90% of the carbon’s original capacity. The result is a powerful closed-loop system —…
At one of the world’s busiest airports, recycled water is taking flight. Christina Beccera Jones of LA Sanitation & Environment explains how water from the Hyperion Water Reclamation Plant will offset potable use at LAX—from air conditioning to toilet flushing—and even replace industrial water within the plant itself. It’s a…
Southern California is building the largest purified recycled water program on the planet — a bold collaboration that will redefine the region’s water future. Johan Torroledo explains how LA Sanitation, the LA Department of Water and Power, and the Metropolitan Water District of Southern California, and are joining forces to…
In the race to remove PFAS from drinking water, about two-thirds of utilities are turning to activated carbon. Brandon Hamilton of NORIT explains how carbon offers a balanced solution with moderate costs, strong performance, and a built-in sustainability edge. Through a process known as reactivation, used carbon is returned, PFAS…
Turning wastewater into drinking water takes more than technology—it takes trust. At the Albert Robles Center, the Water Replenishment District is changing minds by opening its doors to students and the public, showing how science makes recycled water safe, pure, and sustainable. Stephan Tucker says the goal is to replace…
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…
💧 H2O INTRO 👤 Meet Doa Ross, P.E., Deputy General Manager of Engineering at the Southern Nevada Water Authority and Las Vegas Valley Water District In the desert city of Las Vegas, water innovation isn’t just about technology — it’s about people. Ross is helping the region tackle two critical…
The energy for water innovation has never been stronger. ⚡ At WEFTEC 2025, Sivan Zamir of Xylem says the industry is buzzing with ideas — and ready to tackle challenges across every corner of the water cycle. From floods to droughts, and from AI to alternative sources, the next generation…
In the 1990s, Los Angeles faced a choice—keep discharging treated water into the harbor or find a smarter way to use it. Instead of extending its outfall pipe, LA Sanitation joined forces with the Los Angeles Department of Water and Power, which had been injecting potable water into the Dominguez…
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…
Permits for wastewater plants only move in one direction — tighter and tougher. Each time a facility discharges into a river, lake, or ocean, it must meet stricter limits on nutrients like phosphorus and nitrogen to protect ecosystems downstream. That means utilities can’t just monitor anymore — they must remove.…
Inside every wastewater plant, there’s a living workforce — microscopic organisms that break down pollutants and keep our water clean. But sudden changes in what flows in can threaten that delicate biology. That’s why modern utilities use real-time online testing to detect issues like pH shifts, suspended solids, and heavy…
Every storm — or dry spell — changes what flows into our water treatment plants. From rainstorms that pick up pollutants to droughts and conservation efforts that make it more concentrated, utilities are facing influent chemistry that’s in constant flux. These shifts challenge plants built decades ago to handle a…
#WaterQuality #WaterTechnology #watermanagement #SmartWater 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…
Traditionally, it could take months for sewer inspection footage to be reviewed and analyzed—leaving cities to make decisions based on outdated information. Now, AI and cloud processing are giving utilities a current, living view of their underground systems. By rapidly analyzing inspection videos and comparing new data to past results,…
Across the country, water utilities face a growing workforce crisis — not just from retirements, but from invisibility. Few people truly understand what happens behind the scenes to deliver safe, reliable water every day. And often, even those already working in the sector don’t recognize the value of their own…
Artificial intelligence is taking on one of the dirtiest jobs in infrastructure—sewer inspections. By using computer vision and cloud-based analysis, new technology can automatically detect and classify defects in underground pipes, turning hours of manual work into faster, more reliable insights. Eric Sullivan of SewerAI explains how this shift is…
