Smart Digital Water Management – HOFOR Copenhagen’s Live Utility Model
Smart Digital Water Management at HOFOR Copenhagen
TL;DR: HOFOR Copenhagen is turning its water network into a live digital utility, using advanced metering, sensors, and SCADA to detect leaks quickly, cut non-revenue water to world-leading levels, and safeguard long-term supply across Greater Copenhagen.
The global water sector is undergoing a radical digital transformation as utilities rethink how they monitor, operate, and renew assets in the face of rapid urbanisation and climate volatility. Traditional analogue control rooms and periodic meter reads cannot keep pace with increasingly complex hydraulic and customer dynamics. Smart Digital Water Management responds with real-time sensing, analytics, and automation that turn distribution systems into continuously observed and actively orchestrated infrastructure.
From Static Networks to Live Digital Utilities
Smart Digital Water Management replaces episodic measurement with continuous intelligence across the full water cycle. Utilities deploy advanced metering infrastructure to create two-way communication between field assets and control rooms, while sensors and supervisory control systems collect high-frequency data on flows, pressures, and asset status. This real-time data stream enables operators to identify anomalies such as silent leaks, bursts, or demand surges within minutes instead of waiting for billing cycles or customer complaints.
The shift from reactive to proactive operations is driven by mounting pressures on urban systems: growing populations, ageing assets, and more intense climate extremes. Real-time digital visibility allows utilities to stabilise levels of service, reduce water and energy waste, and free capacity in existing infrastructure before committing to costly expansions. It also supports new customer-facing services such as near-real-time consumption feedback and automated alerts that encourage more efficient behaviour.
Governance is central to capturing the value of digital investment. Utilities need clear performance thresholds for non-revenue water, response times, and service continuity, alongside protocols that translate alerts into field activity and capital planning. Trade-offs emerge around cybersecurity, data stewardship, and prioritising interventions when systems surface more issues than can be addressed at once, requiring structured risk-based decision frameworks.
HOFOR Copenhagen’s Smart Network in Practice
By 2026, HOFOR Copenhagen has embraced a fully digital utility model that integrates smart metering, the LEAKman project, and supervisory control and data acquisition across its drinking water system. The utility monitors more than 2,000 kilometres of water pipelines through a dense network of sensors and control points, giving operators a live view of network health and enabling rapid responses to emerging leaks or shifting demand patterns. This digital nervous system transforms leak detection from periodic campaigns into an embedded, continuous process.
In parallel, HOFOR Copenhagen has completed full-scale deployment of advanced metering infrastructure across its customer base, creating a two-way information channel between households, businesses, and the utility. This is complemented by electronic monitoring of more than 2,300 kilometres of sewers and 250 pumping stations, allowing coordinated management of drinking water, wastewater, and climate-related flows. Together, these systems support world-leading efficiency, including non-revenue water levels of around 4 percent in Copenhagen, and position the utility to extend asset lifetimes while managing climate stress.
HOFOR Copenhagen operates with non-revenue water levels of just 4 percent in Copenhagen, a benchmark figure for advanced digital utilities.
Take-Out
Smart Digital Water Management becomes most powerful when treated as a whole-of-utility operating model rather than a collection of pilots. HOFOR Copenhagen shows that combining advanced metering, integrated leakage management, and electronic monitoring of both water and wastewater assets can deliver world-leading efficiency while building resilience to climate and growth pressures.
Expert Follow-Up Questions
How does HOFOR Copenhagen’s use of AMI change day-to-day operations?
Advanced metering infrastructure at HOFOR Copenhagen replaces manual reads with continuous, automated data collection from customers across the service area. Operators can detect abnormal consumption patterns that point to leaks or bursts, prioritise field investigations, and provide customers with near-real-time feedback. This improves billing accuracy, reduces apparent losses, and embeds data-driven decision-making into routine operations.
What role does the LEAKman project play in HOFOR Copenhagen’s digital strategy?
The LEAKman project provides a structured, technology-rich approach to leakage management for HOFOR Copenhagen. It integrates data from smart meters, sensors, and supervisory control systems to calculate water balances in near real time and guide leakage detection teams to the highest-yield areas. This coordinated approach supports the utility’s ability to sustain non-revenue water at exceptionally low levels.
How do sewer and pumping station monitoring systems complement the water supply network?
Electronic monitoring of more than 2,300 kilometres of sewers and 250 pumping stations allows HOFOR Copenhagen to manage drinking water and wastewater as interconnected systems. During storm events, operators can respond to changing hydraulic conditions more quickly, protecting both service levels and environmental performance. Over time, this integrated view informs investment planning for both networks under climate uncertainty.
What are the main governance challenges in scaling Smart Digital Water Management?
Governance challenges include defining clear performance targets, aligning digital investments with long-term asset strategies, and ensuring strong cybersecurity and data privacy practices. Utilities must also develop protocols for triaging the growing number of alerts generated by sensors and analytics to avoid operator overload. Successful governance links digital insights directly to budgets, maintenance programmes, and regulatory reporting.
How can other utilities apply lessons from HOFOR Copenhagen’s experience?
Other utilities can start by setting explicit targets for non-revenue water and service continuity, then designing digital programmes that directly support these objectives. Prioritising pressure management districts, critical sewers, and high-risk assets for early instrumentation can create quick wins and build internal support. Over time, integrating metering, leakage management, and SCADA into a unified operations platform helps replicate HOFOR Copenhagen’s live utility model.
