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 sy
