OT systems are deployed throughout Thames Water’s geographical region, enabling the remote monitoring, control, and data acquisition of thousands of water and wastewater collection, treatment and distribution assets, gathering data insight from over 2.1 million data points.
The demand for Operational Technology solutions across the Water Utility industry is increasing significantly, and it is recognised that OT is critical in enabling us to achieve our strategic goals (including reducing leakage and pollution). We aim to embrace and adopt new technologies to drive a digital transformation so we can exceed our customers’ expectations.
