Yorkshire Water expands predictive condition monitoring programme
01/10/2026
Yorkshire Water, a UK company, is significantly expanding its predictive condition monitoring programme as part of its AMP8 investment. Industrial artificial intelligence (AI) specialist Samotics is set to monitor a further 1200 wastewater sewage pumping station assets and 300 clean water smart pumping assets over the next 18 months.
The expansion is one of the largest deployments of electrical signature analysis (ESA) technology in the UK water sector. It reflects the growing role of asset-level intelligence in helping utilities to reduce pollution incidents, improve network resilience and meet stretching environmental targets in the Yorkshire Water regulatory asset management plan (AMP) for 2025-2030.
The expansion builds on a partnership that began in 2022, when the water company first awarded Samotics a £10 million contract to deploy ESA across its pumping network. The programme has since grown to cover around 2500 assets and won the Utility Week Award for Digital Transformation in December 2025.
Once the AMP8 rollout is complete, Yorkshire Water will have more than 4000 SAM4-monitored assets across its estate, making it the largest single-customer deployment of technology from Samotics to date.
SAM4 uses ESA to monitor industrial equipment by analysing both current and voltage signals captured remotely from motor control cabinets, with AI classifying deviations into specific fault types. At Yorkshire Water, the technology is being applied to submerged sewage pumps, screw pumps and clean water smart pumps.
These are some of the most operationally critical and hard-to-access assets in the network, where conventional vibration sensors are impractical to install. Faults detected include pump blockages, airlocks and misaligned components, often weeks before they would otherwise become visible. The platform is independently validated to have 97% accuracy with a false positive rate of less than 1%.
The decision to scale the programme reflects three years of monitoring operational outcomes. Across the partnership to date, SAM4 has detected 726 developing faults on Yorkshire Water assets, prevented 40 pollution events and delivered a confirmed detection value of £12.87 million. Evaluated across all monitored assets, the programme has delivered a 571% return on investment for Yorkshire Water.
Yorkshire Water plans to integrate SAM4 insights into its strategic data and cloud telemetry platforms, supporting wider visibility and long-term deterioration analysis to inform future investment planning. The 1500-asset expansion is expected to be delivered over the next 18 months, taking the combined Yorkshire Water and Samotics programme into its next phase of scale during AMP8.
