How smart asset monitoring tools create visibility for water networks
Across the globe, water utilities face a daunting set of challenges. Ageing infrastructure and rising energy costs are straining resources. A shrinking maintenance workforce is stretched thin across vast asset fleets, making it harder to keep equipment in optimal condition. Meanwhile, the consequences of operational failure have never been higher: unplanned downtime, energy waste, and environmental harm from sewage spillages can cause significant financial penalties and lasting reputational damage.
For utilities determined to build resilience and efficiency into their networks, visibility of those networks is indispensable. You cannot manage what you cannot see, and millions of their critical assets remain hidden from view. Pumps, motors, and other equipment often operate in harsh or inaccessible environments where traditional monitoring methods fail and sensor installation proves impossible. These blind spots leave utilities vulnerable to failures that could otherwise have been prevented.
Making the invisible visible
At Samotics, we set out to solve exactly this problem. Our flagship monitoring solution, SAM4, uses the electrical signals of industrial assets - the heartbeat of industrial equipment - to deliver continuous, real-time insights into asset health, performance, and efficiency. By placing sensors in the motor control cabinet, rather than on the equipment itself, we make even the most remote or submerged assets visible from the control room. This visibility is already helping water utilities run more efficiently, and is laying the foundation for a smarter, more resilient water sector in the decades to come.
Water utilities face ageing infrastructure, rising energy costs, and limited maintenance teams, challenging efficient equipment operation
SAM4 is very good at monitoring exactly the kinds of assets that give water utilities headaches. For example, pumps frequently get clogged, but SAM4 detects blockages before they result in bigger issues such as pollution events. Instead of having to rely on routine inspections or reacting to failures after they have happened, operators can use the system to identify which assets require attention and when, reducing unnecessary site visits while also preventing catastrophic breakdowns. Pumps are also prone to harmful operating conditions such as dry running, cavitation, or airlocks, and SAM4 detects these issues early, helping to protect equipment and extend its useful life.
SAM4 also helps tackle the issue of rising energy costs. Over time, pumps gradually drift out of their optimal operational range, and every hour a pump operates outside that range wastes energy and shortens its lifespan. However, by continuously tracking real-world performance against design specifications, SAM4 identifies inefficiencies that would otherwise go unnoticed. This enables operators to make adjustments that reduce energy consumption while maximising availability.
What makes SAM4 different
Condition monitoring is not new, but traditional technologies have significant limitations. Vibration sensors, for instance, require physical installation on the equipment itself. This is often impractical or impossible for submerged or remote pumps, and it exposes sensors to corrosive or explosive environments.
Hidden assets and monitoring blind spots leave utilities exposed to preventable failures, downtime, and costly environmental incidents
SAM4 takes a fundamentally different approach. Installed entirely within the motor control cabinet, it can monitor even the most inaccessible assets without direct contact. It does this using Electrical Signature Analysis (ESA), which reads equipment health directly from electrical current and voltage patterns. ESA not only detects developing mechanical and electrical issues, but can also be used to compute live operational parameters such as pressure and flow. And it does all of this continuously, 24/7 - unlike periodic check-ups.
This combination of visibility, depth of insight, and real-time monitoring sets SAM4 apart. It gives water utilities a level of control over their infrastructure that was simply unattainable before.
Equally unique is the collaborative approach we take with our partners. Feedback from utilities and their maintenance teams is central to how we develop SAM4. Their input helps us refine our algorithms, expand to new types of assets, and ensure seamless integration with existing systems like SCADA, CMMS, and digital twins. By working side by side with operators, we ensure our technology delivers trustworthy, actionable insights that make a tangible difference in day-to-day operations. This means SAM4 is not just a monitoring tool, but a living system that evolves with the needs of the water sector.
Meeting water utilities’ real-world challenges
The benefits of smart asset monitoring with SAM4 are clear in practice. For example, in partnership with Yorkshire Water, SAM4 is deployed across more than 600 wastewater treatment sites across the UK. By enabling early detection of pump blockages, SAM4 has helped the utility prevent potential pollution events and avoid millions of pounds in fines. At the same time, SAM4 reduces cyclical inspections, lowers maintenance costs, and improves reliability across the network.
This collaboration demonstrates not only how smart monitoring technology can reduce immediate risk, but also how it can deliver savings and drive operational excellence across the entire water sector. The experience of Yorkshire Water shows how, with the right tools, utilities can move decisively away from reactive firefighting and towards proactive, data-driven management.
Supporting the digital transition
While SAM4 already helps utilities address today’s challenges, its long-term value lies in how it prepares the sector for the future. It can play a central role in digitalisation, for example, which has gone from optional to a strategic imperative for water utilities.

Making the big changes required by digitalisation can feel daunting: How do you move from legacy systems and manual processes to real-time insights and proactive management? Our role at Samotics is to be a partner in this journey. We designed SAM4 to integrate seamlessly with existing infrastructure, reducing barriers to adoption and ensuring a smooth transition to digital operations. The platform scales as networks grow, adapts to new technologies, and evolves alongside regulatory changes.
Equally important, SAM4 empowers utilities to engage more effectively with their customers. By providing transparent consumption data and actionable insights, utilities can foster stronger relationships with their customers and encourage them to use water more sustainably.
Building resilience for the future
The mounting pressure on water infrastructure is experiencing demands for a shift toward smarter, more resilient systems. SAM4 is designed to play a pivotal role in this transition, too. By feeding accurate, real-time data into higher-level systems such as digital twins, it makes those tools smarter and more reliable. After all, a digital twin can only optimise performance if the underlying asset data is trustworthy.
By detecting issues like blockages, cavitation, or dry running early, SAM4 prevents breakdowns and extends the useful life of pumps
SAM4 is also bringing monitoring closer to the source by integrating directly into variable frequency drives, creating what we like to call a “VFD with a PhD.” This innovation shows how drives themselves can become a platform for advanced monitoring, turning what was once a special project into a routine capability.
Ultimately, we believe that Electrical Signature Analysis, pioneered by Samotics, will become the standard for asset maintenance. It represents the first technology to combine the precision, versatility, and cost-effectiveness needed for large-scale deployment - finally making industry-wide transformation achievable.
Embedding ESA as a default capability will mean that every new pump or retrofit comes with built-in visibility. Issues like cavitation or bearing degradation will show up as early, trusted signals rather than emergency shutdowns. Furthermore, machines will evolve to keep pace with advances in software and analytics. Data-driven networks will balance loads, minimise energy use, and prevent failures automatically. Context-aware pumps integrated with sophisticated digital twins will empower teams to optimise performance, balance cost against resilience, and swiftly adapt to changing conditions. The firefighting that has long defined maintenance culture will give way to operators being able to act proactively, resilient, and intelligent, self-optimising systems.
By creating networks of smart, connected assets, ESA will help fundamentally transform the water sector. While this evolution won't happen overnight, every step utilities take today builds the foundation for truly adaptive water infrastructure.
Full asset visibility for the water sector
Electrical Signature Analysis will underpin smart, connected, self-optimising water networks, transforming asset maintenance across the sector
Looking five to ten years ahead, our vision for the water sector is complete asset visibility. Every critical piece of equipment will be monitored in real time, no matter how remote or inaccessible, giving engineers the insights they need exactly when decisions matter most.
If I could leave one message with leaders in the water sector, it would be this: you have the power to transform water infrastructure from a collection of ageing assets into an intelligent, self-optimising network. The technology exists. The business case is proven. The only barrier is the decision to begin.
That transformation starts today. The utilities that embrace smart monitoring now won't just solve immediate challenges - they'll define what modern water infrastructure becomes. The question isn't whether this evolution will happen, but whether your organisation will lead it.
