Summary of the contracting process

Yorkshire Water Services Limited procured a fully integrated Electrical Signature Analysis (ESA) platform and managed predictive maintenance service for its motor-driven asset base. The service combines continuous monitoring of three-phase voltage and current signatures, hardware installed in motor control centres, predictive analytics and expert condition-monitoring review. It is intended to improve operational resilience, asset reliability, energy efficiency and environmental performance. Required monitoring includes pumps and rotating assets, with detection of blockages, ragging, airlocks, burst rising mains, cavitation, dry running, loss of prime, inefficient operation and excessive energy consumption. The solution also provides fault diagnosis, impact assessment, corrective recommendations, reporting, technical support and 24/7 monitoring. Integration with SCADA, telemetry, SAP and GIS is required. Delivery covers Yorkshire Water’s UK operational estate.

The procurement is complete and was awarded by direct award to Samotics Ltd as a single supplier. It comprised one lot and was assessed as suitable for small and medium-sized enterprises. The awarded service value is £5,400,000 excluding tax, or £6,480,000 including tax. The initial contract runs from 1 July 2027 to 30 June 2030, with renewal available to a maximum extent date of 30 June 2035. Break clauses apply at years three and five. The direct award was justified on technical grounds: Yorkshire Water concluded that Samotics’ SAM4 ESA platform was uniquely able to combine continuous monitoring, predictive maintenance, event detection, energy monitoring, expert validation and utility-system integration in one commercially proven service. The procurement falls under the utilities regime and exceeds the applicable threshold.

This requirement indicates demand for mature condition-monitoring technology and managed predictive maintenance across a large water-utility asset base. A credible future competitor would need a commercially available, operationally proven platform rather than a development-stage product, with successful outcomes for other water companies and preferably UK water and sewerage companies. The required capability spans Electrical Signature Analysis using motor-control-centre data, artificial intelligence and machine learning, expert analyst validation, near-real-time fault detection, diagnosis and corrective recommendations. Suppliers would also need to support continuous 24/7 monitoring, performance reporting and technical assistance. Strong interoperability with SCADA, telemetry, SAP, GIS and existing network devices and sensors is central. The buyer’s direct-award rationale shows that an integrated end-to-end service is more competitive than isolated vibration, thermography, telemetry or motor-analysis products.

Notice Information

Notice Title

Condition Based Monitoring - ESA Devices

Notice Description

YW seek a fully integrated Electrical Signature Analysis (ESA) platform and managed predictive maintenance service to improve operational resilience, asset reliability, energy efficiency and environmental performance across its motor-driven asset base. The management of rotating assets through reactive maintenance, periodic inspections or disconnected monitoring systems can result in reduced visibility of asset condition, increased risk of unplanned failures, higher maintenance costs and avoidable operational and environmental impacts. A unified monitoring solution is required to provide continuous condition assessment, actionable intelligence and estate-wide visibility from a single platform. The solution must deliver all of the following capabilities within a single, integrated platform and managed service: Electrical Signature Analysis (ESA) -Continuous monitoring of three-phase voltage and current signatures from motor-driven rotating assets through hardware installed within motor control centres (MCCs), without the need for sensors mounted directly on assets. The solution shall collect and analyse electrical data continuously to identify developing faults and operational issues. Predictive Maintenance Analytics- A combination of artificial intelligence, machine learning and expert analyst validation capable of identifying developing faults before failure occurs. The solution shall provide early warning notifications together with fault diagnosis, operational impact assessment and recommended corrective actions. The platform shall detect operational asset and network events including: - Blockages, clogging and ragging: A shift in the pump's electrical load caused by restricted or abnormal flow - Airlocks: A characteristic load-signature change when trapped air disrupts normal flow - Burst rising mains: Loss of system pressure and altered flow following a burst, seen as a change in the pump's load signature - Cavitation: The load signature characteristic of a pump operating in cavitation - Dry running and loss of prime: An abnormally low load condition characteristic of dry running - Off-curve or inefficient operation: Operation sitting away from the pump's best-efficiency point - Excess energy consumption: Elevated true power for the duty delivered The solution should provide real-time or near-real-time identification of these events to enable proactive intervention and reduce operational risk. The platform shall be supported by a human-in-the-loop managed service where findings are reviewed and validated by qualified condition monitoring specialists prior to notification. The service shall provide: - Continuous asset monitoring - Expert validation of findings - Recommended corrective actions - Performance reporting - Ongoing technical support The managed service shall operate on a 24/7 basis The platform must be fully developed and commercially available. For clarity this means the product is not in early-stage development, not unproven, and not awaiting first deployment or first operational results. The solution must have already demonstrated successful outcomes with other water companies, preferably within the UK and particularly with other WASCs. The platform must be capable of integrating with core utility systems (e.g., SCADA, telemetry, SAP, GIS) and must meet minimum interoperability requirements to interpret data from devices and sensors currently deployed in our network

Procurement Information

Following a review of the predictive maintenance and condition monitoring market, it has been determined that proposed contractor is uniquely positioned to deliver the required capability through its SAM4 Electrical Signature Analysis (ESA) platform and managed service. Yorkshire Water requires a single, integrated solution capable of delivering continuous monitoring, predictive maintenance, operational event detection, energy performance monitoring, expert-validated diagnostics and enterprise system integration across a broad portfolio of motor-driven assets. The solution must be operationally proven, commercially mature and capable of supporting large-scale deployment within utility environments. Market assessment indicates that while alternative suppliers can provide individual elements of condition monitoring, such as vibration analysis, telemetry analytics, thermography or motor current analysis, no other supplier has demonstrated the ability to provide all required capabilities within a single managed platform. The solution needed to be commercially available, already deployed with proven outcomes in other water companies (particularly UK WASCs) and ready for immediate use rather than still in development or awaiting first implementation. This is as Yorkshire Water are prioritising mitigation of the risks in implementation and risks of poor outcomes.
