STOCKHOLM, SWEDEN – In a move that signals a significant leap forward for European smart city infrastructure, Netmore Group has officially announced a large-scale collaboration with the Danish water utility Aarhus Vand and the global metering technology leader Kamstrup. The partnership is set to deploy approximately 69,000 digitally connected water meters across Aarhus Municipality, Denmark’s second-largest city.
This initiative, powered by Netmore’s carrier-grade LoRaWAN® (Long Range Wide Area Network) infrastructure and Kamstrup’s advanced acoustic leakage detection technology, represents one of the most ambitious "Massive IoT" (Internet of Things) projects in the Nordic region to date. By transitioning from manual readings to a fully automated, real-time data ecosystem, the project aims to redefine resource management, enhance consumer transparency, and safeguard Denmark’s precious water supplies for the next decade.
I. Main Facts: A Tripartite Alliance for Sustainability
The core of the project involves replacing the aging mechanical or traditional digital meters across Aarhus with 69,000 smart units. These devices are not merely counters; they are sophisticated sensors capable of detecting microscopic vibrations associated with leaks.
The Collaborative Framework
The project is built on a specialized division of labor among three industry leaders:
- Netmore Group: Acting as the network operator, Netmore provides the connectivity backbone. They are deploying a "carrier-grade" LoRaWAN network, ensuring that data from meters—often located in basements or underground pits—can penetrate through concrete and soil to reach the utility’s servers.
- Aarhus Vand: The municipal utility provider serves as the project lead and end-user. For them, the project is a strategic shift toward becoming a data-driven utility, moving away from "estimation-based" billing to "actual-usage" billing.
- Kamstrup: The Danish technology giant is supplying the hardware. Their meters are renowned for their longevity (often exceeding 15 years of battery life) and their precision in extreme environments.
The Objective
The primary goal is the total elimination of manual meter readings by 2030. Beyond administrative efficiency, the project is designed to provide a granular view of the city’s water network, allowing for the immediate identification of "non-revenue water"—water that is pumped but lost due to leaks before it reaches the customer.
II. Chronology: From Pilot Success to 2030 Vision
The journey toward a smart Aarhus did not happen overnight. It is the result of rigorous testing and a phased strategy designed to mitigate the risks associated with large-scale technology shifts.
The Tranbjerg Pilot (2024–2025)
Before the full-scale rollout was greenlit, the partners conducted an extensive pilot program in the suburb of Tranbjerg. Approximately 1,000 households were equipped with the new Kamstrup meters connected via Netmore’s LoRaWAN network.
The pilot was crucial for validating the "indoor-to-outdoor" signal penetration. In urban environments, water meters are frequently shielded by heavy infrastructure. The Tranbjerg trial proved that the LoRaWAN protocol could maintain a 99% data packet success rate even in challenging topographical conditions. Following this validation, the transition to full deployment was authorized.
The Rolling Deployment (2026–2030)
As of August 25, 2026, the official rollout has commenced, beginning once again in the Tranbjerg area to build on existing infrastructure. The deployment is being managed by Eltel, a leading Nordic provider of technical services for critical infrastructure.
The schedule is designed to be "area-by-area." This localized approach allows Netmore to densify the network as needed, ensuring that as soon as a meter is installed by Eltel, it can immediately begin transmitting data. The project is expected to reach its full 69,000-unit capacity by the end of 2030, at which point Aarhus Municipality will possess one of the most digitally integrated water networks in the world.
III. Supporting Data: The Economics of Smart Metering
To understand why Aarhus Vand is making this investment, one must look at the data surrounding water waste and operational costs.
Addressing Non-Revenue Water (NRW)
Globally, it is estimated that between 25% and 50% of all treated water is lost to leaks in the distribution network. While Denmark has some of the lowest loss rates in the world (often below 10%), the "last mile" of leakage—occurring within private property or small distribution pipes—remains difficult to track.
- Real-time Detection: Traditional meters are read once a year. A leak starting in January might not be noticed until the following year’s bill. With smart meters, a constant flow (indicating a burst pipe or a running toilet) can be flagged within 24 hours.
The LoRaWAN Advantage
The choice of LoRaWAN over cellular (NB-IoT) or other protocols is backed by specific technical data:
- Power Consumption: LoRaWAN devices consume significantly less power, enabling a 16-year battery life for the Kamstrup meters. This aligns with the depreciation cycle of the hardware.
- Cost-Efficiency: Because LoRaWAN operates on unlicensed spectrum, the total cost of ownership (TCO) for Netmore and Aarhus Vand is significantly lower than traditional cellular contracts, making "Massive IoT" financially viable.
IV. Official Responses: Leadership Perspectives
The leadership teams of the three involved entities have emphasized that this project is a blueprint for the future of European utilities.
Helle Pernille Hansen, Specialist Manager at Aarhus Vand, highlighted the necessity of reliability:
"Delivering reliable meter reading demands a network that meets high-performance requirements consistently, not just in ideal conditions, but across every meter, every day. Our pilot demonstrated that LoRaWAN meets those standards in practice, and our partnership with Netmore and Kamstrup gives us the confidence to scale."
Eric Collinder, Country Manager Nordics at Netmore, focused on the role of connectivity in resource management:
"We are pleased to support Aarhus Vand in delivering a modern digital water infrastructure. Reliable, carrier-grade connectivity is essential for smart metering deployments. This project demonstrates how the right technology and partners can help utilities improve resource management and provide consumers with better data."
Henrik Jensen, SVP at Kamstrup Water, noted the synergy between hardware and software:
"Smart water metering only delivers its full value when data arrives reliably and on time. Kamstrup’s meters are engineered to perform across the full range of installation environments, and Netmore’s network ensures those capabilities translate into the consistent read rates Aarhus Vand needs to meet its operational and customer service targets."
V. Implications: Beyond the Meter
The rollout of 69,000 smart meters in Aarhus has implications that reach far beyond the borders of Denmark. It serves as a case study for the "Green Transition" and the evolution of the "Smart City."
1. Consumer Empowerment and Behavioral Change
For the first time, residents of Aarhus will have online access to their consumption patterns. Behavioral economics suggests that when consumers can see their usage in real-time, they are 5–15% more likely to implement conservation measures. This transparency transforms the consumer from a passive payer into an active participant in water conservation.
2. Preventive Infrastructure Maintenance
For Aarhus Vand, the data harvested from these meters allows for "predictive maintenance." By analyzing flow data, the utility can identify aging sections of the city’s pipe network before a catastrophic burst occurs. This shift from reactive repairs to proactive upgrades can save millions in emergency repair costs and prevent urban flooding.
3. The Scalability of Massive IoT
This project reinforces Netmore’s position as a global leader in Massive IoT. By successfully managing 69,000 endpoints in a single municipality, Netmore proves that LoRaWAN is ready for large-scale utility adoption across Europe. With Netmore operating in 18 countries and backed by Polar Structure, this project is likely a precursor to similar rollouts in other major European hubs.
4. Environmental Stewardship
Denmark has long been at the forefront of environmental policy. By minimizing water waste, Aarhus is reducing the energy required for water treatment and pumping, thereby lowering the city’s overall carbon footprint. In an era of increasing climate volatility and potential water scarcity, the ability to account for every drop of water is no longer a luxury—it is a necessity for urban resilience.
Conclusion
The collaboration between Netmore, Aarhus Vand, and Kamstrup is more than a technical upgrade; it is a fundamental shift in how cities interact with their most vital resource. As the rollout progresses through 2030, the world will be watching Aarhus as a model for how technology, when properly integrated, can create a more sustainable and efficient urban future.
