439 Innovating Water for Smart Cities: Christine McHugh’s Vision

What happens when cities become “networked”—and water systems start telling us what they need in real time? In this episode, Trace Blackmore speaks with Christine McHugh (CEO, White Strand Development) about practical smart-city strategies for water: real-time monitoring, digital twins, and IoT/AI approaches that turn Legionella control from periodic testing into continuous risk management. Christine frames smart water not as gadgets, but as a disciplined, data-driven process that improves human health, operational efficiency, and insurability. Building the “Networked” City: A Practical Definition   Christine defines a smart city as a networked one—linking health, energy, waste, and water through technology that measures and correlates across systems. The aim isn’t novelty; it’s safer drinking water and safer water environments via better data and faster decisions. Digital twins, decentralized treatment, and AI-enabled pattern recognition help teams move from “single point-in-time readings” to persistent trends they can act on. Legionella Risk, Reframed as Strategy   Most water programs still sample periodically, waiting days for results. Christine argues the future is pattern-based, proactive control: track temperature, stagnation/flow, and disinfectant continuously; intervene when pattern thresholds indicate elevated risk. This lens aligns water quality, human wellness, and insurance risk reduction, encouraging property insurers and building owners to incentivize water science as part of smart-building operations.  From Sensors to Sense-Making: Hierarchy, Data Lakes, and Reporting  Adding devices isn’t enough. Christine stresses a hierarchy of sensors and data governance so operations, engineering, and ESG teams aren’t running conflicting reports from siloed sources (BMS vs. cloud dashboards). Her model: create a data lake with agreed-upon sources of truth and standardized outputs so every stakeholder “sees the same movie.”  Case Studies & What “Good” Looks Like  Christine highlights programs that combined water management plans, continuous disinfectant monitoring, and campus-scale digital twins—reducing manual tests, achieving compliance, and cutting consumption. European hospitals using IoT on hot-water systems report faster compliance and fewer manual interventions. The pattern: real-time insight + trained people + maintenance and reporting contracts = measurable risk reduction.  Cybersecurity: Close the Back Doors  Smart water raises legitimate cyber concerns. Christine’s guidance: encrypt all sensor communications, hire experts to penetration-test your own systems, and watch for unexpected bridges (e.g., HVAC or even “non-critical” devices) into critical networks. OT/IT segmentation, alert transparency, and a culture of continuous testing matter as much as the sensors themselves.  Public–Private Partnerships (with Academia)  The fastest path to adoption pairs public oversight and access to infrastructure with private-sector technology and capital—and an academic partner for research and validation. Clear performance metrics and maintained as-builts keep pilots honest and scalable.  Resilience: Droughts, Floods, and Stormwater  Smart networks matter beyond Legionella. Real-time consumption, leak detection, and pressure management minimize waste during droughts; stormwater and wastewater sensors prevent overflows that contaminate receiving waters during floods. Long-running sensor programs abroad show how a single resort area eliminated contamination events by instrumenting the system and responding to alerts.  Emerging Tech to Watch  From self-healing pipes and biosensors to drone inspections and AI-orchestrated networks, Christine sees water systems becoming more like natural ecosystems—self-regulating, adaptive, and resilient—while humans supervise exceptions and validate performance.  For industrial water professionals, the takeaway is clear: treat smart water as an integrated risk-management system, not a pile of devices. Invest in sensor hierarchy, unified data, and team training, and align the work with safety and insurance outcomes. That’s how you protect people, performance, and the balance sheet.

438 Innovative Water Treatment Chemistry with Matheus Paschoalino

Can a carbon-negative, bio-based molecule replace legacy phosphonates and help you use less azole—without sacrificing corrosion performance? In this episode, host Trace Blackmore, CWT, welcomes Matheus Paschoalino, PhD Senior Business Development Manager and Microbial Control SME of Solugen, to unpack polyhydroxycarboxylic acids (PHCs) and how they’re changing cooling-water programs from the field up. We cover HEDP replacement in light-duty systems, azole enhancement in copper-challenged waters, a second-generation cut for heavy-duty heat flux, and PHC behavior with oxidizers and non-oxidizer biocides.  From Bioforge to Basin: How PHCs Are Made and Why It Matters  Paschoalino explains Solugen’s chemo-enzymatic “Bioforge” approach that oxidizes sugars (corn-syrup feedstock) into PHCs with very high yield and no practical byproducts—a pathway validated as carbon-negative. He outlines how different “cuts” (monoacid-rich vs. diacid-rich) map to different use cases, and notes current manufacturing capacity and adoption across hundreds of towers.  Replacing HEDP in Light-Duty Programs  For hospitals, HVAC, and other light-duty systems, PHCs have fully replaced HEDP as the anodic corrosion inhibitor while keeping PBTC for scale, enabling lower total phosphorus formulations with equal or better performance compared to status-quo organics.  Azole Enhancement, Free Copper, and Real-World Cost  Field work showed PHCs chelate metals quickly, protecting azole demand when free copper is present (e.g., after oxidizer flushing) and reducing expensive azole overdosing. One university case dropped an adjunct 8-ppm azole feed by pairing the base 3–4 ppm azole with PHC, yielding both corrosion control and lower discharge costs.  Second-Generation PHCs for Heavy-Duty Heat Flux (Toward “Neutral Phosphorus”)  At higher heat flux and stabilized-phosphate conditions, a diacid-rich second-generation PHC proved more stable, enabling orthophosphate reduction and opening a path toward “neutral phosphorus” programs that leverage background phosphate in municipal make-up. Bench data also show synergy with trace metals (e.g., zinc).  Biocide Potentiation and Where It Works Best PHCs remain stable with oxidizers like chlorine dioxide and bleach. Their most compelling synergy shows up with non-oxidizers and peracetic acid (PAA): as a biocide potentiator, PHCs can reduce the need to overdose actives such as THPS, glutaraldehyde, quats, and DBNPA by first complexing interfering metals (e.g., Fe/FeS), letting the biocide perform as intended.  Not “Bug Food”: Pilot Cooling Towers and Oxidizer Demand  To address the industry’s biggest concern with bio-based chemistries, Solugen ran side-by-side outdoor pilot cooling towers under identical bleach control. Result: comparable oxidizer usage and consistently low counts versus HEDP—evidence that PHCs don’t fuel biofilm.  Chelation Mechanics, Polymer Savings, and White Rust  PHCs chelate beyond acid-group stoichiometry thanks to multiple hydroxyls and conformational effects—critical for controlling dissolved metals and protecting films. In stressed heat-flux/chlorine conditions, PHCs reduced calcium-phosphate fouling versus HEDP, often allowing polymer dosage cuts. Early data also show promise for white-rust mitigation on galvanized systems, with the diacid-rich cut delivering the strongest reductions.  For practitioners, the message is pragmatic: PHCs aren’t “lab curiosities.” They’re fielded at scale, enabling lower-phosphorus programs, protecting costly azole inventories, widening the operational window under oxidizer stress, and potentiating select biocides—while staying compatible with common metals. If you manage cooling assets under cost, compliance, and performance pressure, this episode gives you a clear technical playbook to evaluate.  Listen now, review the papers in the show notes, and test a pilot where it counts—on your heat exchangers.  Stay engaged, keep learning, and continue scaling up your knowledge!    Timestamps  02:15 - Trace Blackmore shares a quick personal open: spotting the Goodyear Blimp (100th anniversary), using memories as fuel rather than limits, and a mindset reset around the word “can’t.”  06:42 - Upcoming Events for Water Treatment Professionals   09:23 - Water You Know with James McDonald  11:41 - Interview with Matheus Paschoalino, Senior Business Development Manager and Microbial Control SME of Solugen  12:02 - HEDP replacement in light-duty programs; lower total phosphorus without losing performance  19:13 - Heavy-duty heat flux: second-generation (diacid-rich) PHCs and reducing orthophosphate  20:39 - “Neutral phosphorus” approach  27:42 - Biocide potentiation: synergy with PAA; strongest effects with non-oxidizers (e.g., THPS)  33:03 - “Bug food?” Pilot side-by-side cooling towers (Houston)  37:39 - HEDP systems fouled with calcium phosphate while PHC system showed only minor patching (CTI paper)  41:44 - Early evidence: white-rust mitigation on galvanized systems (seeking field partners)    Quotes  “Use your past as history, not as a limiter.” - Trace Blackmore  “Plan where you’ll be; you never know what you’ll learn or who you’ll meet.” - Trace Blackmore   “First-gen PHCs let us replace HEDP in light-duty programs and keep performance with lower total phosphorus.” - Matheus Paschoalino  “Non-oxidizing biocides work best with PHCs—we target the metals first so you stop over-dosing the biocide.” - Matheus Paschoalino  “We like to be very conservative… we start with the laboratory; we start with light duty.

436 Raising the Bar: Legionella Management & Industry Standards

With those words, Jemma Tennant highlights one of the most profound differences between Legionella management in Europe and the United States. In this episode of Scaling UP! H2O, host Trace Blackmore welcomes Jemma Tennant, Chair of the Water Management Society (WMSoc), to explore how legislation, enforcement, and professional training shape the fight against Legionella.   Proactive Regulation and Duty of Care  The UK treats Legionella as a foreseeable and preventable risk. Jemma explains how laws like the Health and Safety at Work Act and COSHH Regulations require mandatory Legionella risk assessments, temperature monitoring, and written control schemes—even when no cases have occurred. This contrasts with the U.S., where ASHRAE 188 serves as guidance rather than enforceable law, often triggering enforcement only after outbreaks.  Jemma shares a case study where a housing association was fined £1.2 million despite no recorded illness, underscoring the UK’s proactive stance on protecting public health. Hospitals, Design, and Emerging Challenges  From hospital plumbing layouts to new “waterless” intensive care units, Jemma details how design choices can either mitigate or magnify waterborne risk. Scotland’s model of involving water safety groups at the design stage provides a proactive example for healthcare worldwide. She also outlines how climate change, net-zero initiatives, and rising ambient temperatures are complicating control strategies across Europe.  Raising Standards Through Collaboration  As Chair of WMSoc, Jemma is leading efforts to raise industry standards and reverse what she calls a “race to the bottom.” She describes partnerships with AWT in the U.S. and LMAG in Australia to share expertise across borders. The episode also explores her pursuit of the Certified Water Technologist (CWT) credential and her vision for adapting the certification for UK professionals.  Conclusion  This conversation is a call to action for water treatment professionals everywhere: regulations, standards, and collaboration matter. Whether in cooling towers, hospitals, or housing estates, Legionella management requires vigilance, shared knowledge, and a commitment to raising the bar.

435 Optimizing Legionella Control Strategies with Dr. Vincenzo Romano Spica

Legionella remains one of the most complex challenges for water professionals worldwide. How do we balance effective monitoring with realistic costs—and which strategies deliver true public health impact? In this episode, Trace Blackmore welcomes Dr. Vincenzo Romano Spica,  Head Public Health University of Rome "Foro Italico to explore new insights from his comparative research on Legionella control. Reframing Legionella Risk  Dr. Spica explains why public health data increasingly points to Legionella pneumophila—not all Legionella species—as the primary concern for human health. He shares how pan-European data modeling and peer-reviewed studies demonstrate that broad-spectrum monitoring may overburden systems without delivering proportional safety gains.  Cost-Benefit Models and Sustainability  Water professionals know that testing and compliance require resources. Dr. Spica discusses cost-benefit analysis frameworks that help decision-makers evaluate where investments deliver the greatest reduction in risk. He also highlights the sustainability implications of over-testing, from lab resources to environmental waste streams.  European Regulations and Legal Liability  The conversation also explores the European Drinking Water Directive 2020/2184, national approaches to Legionella, and how liability shifts when contamination is detected. Dr. Spica’s insights illuminate what building owners, operators, and regulators must weigh as they update management plans.  Conclusion  For engineers, operators, and technical managers, this episode provides a clear framework for thinking about Legionella beyond routine testing. It’s about focusing on the pathogen that truly drives disease outcomes, aligning regulatory strategy with science, and applying resources where they matter most.  Stay engaged, keep learning, and continue scaling up your knowledge!    Timestamps    02:24 - Trace opens the episode, welcoming listeners to Legionella Awareness Month and framing the call to action  05:37 - Water You Know with James McDonald  10:04 - Upcoming Events for Water Treatment Professionals   14:06 - Trace introduces Dr. Vincenzo Romano Spica, Head of Public Health at the University of Rome Foro Italico   17:22 - Dr. Spica outlines why Legionella pneumophila is the main pathogen of concern in Europe 35:04 - Dr. Spica explains Disability Adjusted Life Years (DALYs) as a measure of public health burden  44:08 - Monitoring strategies and how different culture methods affect outcomes  46:16 - The role of water temperature in Legionella proliferation    Quotes  “Not all Legionella are equal—public health data shows us it’s Legionella pneumophila that drives the real risk.”  “Testing everything may look safer on paper, but in practice, it diverts resources from where they can have the greatest impact.”  “Risk management should not be a checklist; it should be a strategic allocation of resources aligned with outcomes.”  “European data models show that a targeted approach can deliver both better safety and greater sustainability.”    Connect with Dr. Vincenzo Romano Spica   Phone: +39.338.935.1976  Email: vincenzo.romanospica@uniroma4.it  LinkedIn: vincenzo romano spica | LinkedIn        Guest Resources Mentioned   Legionnaires’ Disease Surveillance and Public Health Policies in Italy: A Mathematical Model for Assessing Prevention Strategies by Dr. Spica et. al  Alessando Cassini’s Burden of Infectious Diseases in Europe methodological challenges and opportunities for public health policy  NLM’s Impact of infectious diseases on population health using incidence-based disability-adjusted life years (DALYs): results from the Burden of Communicable Diseases in Europe study, European Union and European Economic Area countries, 2009 to 2013  Supplemental information: Impact of UAT Diagnostic Methods on Estimates of Legionnaires’ disease Caused by non-pneumophila Legionella    Scaling UP!
