Microplastics, Infrastructure Failures, and Stormwater News

Digital tools are changing how water utilities handle flooding

In this episode of Talking Underwater, Stormwater Solutions Head of Content Sarah Kominek speaks with Manuel Parra of Xylem Vue about how digital tools are changing the way municipalities prepare for and respond to flooding. The conversation explores how communities can use existing infrastructure more effectively, why high-quality data matters as much as data collection, and how predictive analytics, modeling, and AI can support faster, smarter decisions during wet weather events. Parra also shares real-world examples from Houston and Buffalo to show how practical, scalable flood-control technology can help reduce risk, improve operations, and protect lives.  Key Moments  * 00:00 - Episode introduction and overview of why flood prediction is becoming more urgent  * 01:54 - How digital flood-control applications help municipalities respond to severe weather events  * 03:11 - Tools emergency managers use today, from sensors and rain gauges to models and AI  * 04:24 - Why data quality, not just data quantity, is critical for effective flood response  * 06:25 - Houston example: underpass flood detection and public alerts using existing infrastructure  * 08:05 - Buffalo example: preemptive system management that helped reduce combined sewer overflows  * 10:12 - What integrating digital technology with existing stormwater infrastructure looks like in practice  * 11:35 - The role of predictive analytics and AI in supporting operator decisions  * 13:16 - How climate variability changes the baseline and why models must keep evolving  * 14:32 - Regulatory and liability considerations tied to better infrastructure management  * 15:34 - How smaller or under-resourced communities can adopt lower-cost, right-sized solutions  * 17:34 - Typical lead times for flood prediction and why every minute counts  * 18:35 - Final takeaway: flood technology does not have to be overly complex to make a major impact  About the Podcast       Talking Under Water is the premier podcast for the water industry, including municipal water and wastewater, residential water treatment, storm water management and erosion control.

Voices from Water Week 2026: Ensuring Resilience and Affordability in Water Systems

In this episode Talking Under Water co-host Bob Crossen discusses Water Week 2026 where key figures recorded messages from the event. The episode features firsthand perspectives from water sector leaders who gathered in Washington, D.C., for the annual Water Policy Fly‑In to advocate for national water priorities. Through voice memos from leaders at the Water Environment Federation, American Water Works Association, National Association of Clean Water Agencies, and utility representatives from across the country, listeners hear a consistent message: federal investment in water infrastructure is critical. Speakers point to concerns around declining State Revolving Fund support, the need for long‑term affordability, and the growing financial and regulatory pressures of PFAS management. Utility leaders explain how tools like SRF loans help keep water affordable for customers, especially as infrastructure ages and compliance costs rise. Crossen also reflects on related conversations with utility directors beyond Capitol Hill, tying Water Week priorities to broader operational challenges such as biosolids management, inflow and infiltration, and emerging technology needs. Together, these insights illustrate why coordinated advocacy and sustained federal support remain essential to the health, resilience, and affordability of water and wastewater systems nationwide.

The battle over Colorado River resources is brewing

In this episode Talking Under Water co-hosts discuss escalating water use restrictions in Denver, the broader legal and political fight over Colorado River allocations, and what differing conservation strategies reveal about the future of water management in the West. The conversation begins with Denver Water’s declaration of a Stage 1 drought, outlining outdoor watering limits, fines for repeat violations, and how these measures compare with long‑standing, highly structured conservation programs in Southern Nevada. The episode then zooms out to the Colorado River basin, breaking down the growing split between upper and lower basin states, the looming possibility of Supreme Court litigation, and disagreements over delivery obligations rooted in the 1922 Colorado River Compact. The hosts explore what water scarcity could mean for cities, agriculture, and priority water rights, and why the lack of a statewide curtailment plan in Colorado raises serious questions. In additional news, the podcast reflects on the passing of Dr. James Barnard, a pioneering figure in biological nutrient removal, and covers bipartisan federal efforts to fund advanced wastewater treatment for PFAS. The episode rounds out with updates on sediment cleanups, beach water quality monitoring, stormwater permitting debates, and ongoing concerns about affordability as utilities face increasing regulatory and infrastructure demands.  Show Notes: Denver water restrictions expected to begin March 25 amid near-record low snowpack [https://www.9news.com/article/news/local/denver-water-restrictions-set-to-begin-march-25/73-85c719b8-30f1-4f2d-8bea-b9de06e65251] Denver Water Rules for outdoor water use [https://www.denverwater.org/residential/rebates-and-conservation-tips/summer-watering-rules] Denver Water’s 2026 Water Budget Program [https://www.denverwater.org/business/rebates-and-conservation-tips/water-budget-program] The Colorado River is on the brink of possible forced water cuts.

Different by Design: Turning 30 Years of Expertise into Utility Confidence

Utilities hold more power than they think. In this day and age, with a few taps of a keyboard, information is literally at your fingertips. For some, that’s a simple Google search, and others a query with a generative AI tool. But for those more enterprising utility leaders, operators and managers, that interaction in peer groups on Facebook, LinkedIn, Discord or other platforms.  They share best practices with each other, answer questions, provide guidance on management decisions, and it is a forum for open and honest thoughts about products in the market place. Utilities are holding vendors accountable with each other.  Bruce Bharat, regional president of the Americas for Kamstrup, has taken notice of this trend and other purchasing influences in the market. In this sponsored interview, Bob Crossen talks with him about how the Information Age has changed the way modern utilities interact with Kamstrup, why that drives innovation and how being different is a good thing.  This episode is sponsored by Kamstrup Resources:  * WaterWorld Digital Edition [https://www.waterworld.com/magazine]  * SWS Digital Edition [https://www.stormwater.com/magazine]  * WWD YouTube Channel [https://www.youtube.com/@wastewaterdigest?themeRefresh=1]  About the Podcast      Talking Under Water is the premier podcast for the water industry, including municipal and industrial water and wastewater, residential water treatment, storm water management and erosion control.
