Thames Water with Vodafone Business IoT

In 2024, we partnered with Vodafone Business to support Thames Water’s essential digital transformation ahead of the 2027 PSTN switch-off. By implementing a robust dual-managed path platform, we ensured reliable and secure connectivity for 3,500 telemetry sites, helping the UK’s largest water utility to shift toward proactive maintenance and enhanced data-driven decision-making.

Thames Water, responsible for supplying water and waste services to over 16 million people across London and the Thames Valley, relied heavily on the Public Switched Telephone Network (PSTN) for its telemetry communications. However, with the PSTN being phased out by 2027, they needed a forward-looking solution to continue monitoring water flow, levels, and other key data in real time. The existing system often caused delays in data reporting, affecting operational efficiency.

To ensure a seamless transition and minimize disruption, Thames Water sought a connectivity partner with expertise in secure, reliable communications for critical national infrastructure. That’s where we came in.

We worked closely with Vodafone Business to deliver a tailored solution, leveraging our expertise in critical connectivity. Together, we implemented a dual-managed path platform using the Vodafone-CSL modem, designed to provide continuous, resilient communications across all telemetry sites. This system allows Thames Water to capture real-time data and ensure immediate transmission to their central control room, vastly improving their operational capabilities.

With over 3,500 sites transformed, our solution delivers:

Instant Data Transmission: Previously, data was logged locally and often delayed until the end of the day. Now, data is transmitted in real time, giving Thames Water’s engineers immediate insights.

Increased Accuracy and Efficiency: The faster data flow has allowed Thames Water to detect issues sooner and move toward a proactive maintenance model, reducing time spent on reactive repairs.

Futureproofed Communications: As the PSTN switch-off approaches, our resilient solutions ensure Thames Water’s telemetry assets remain operational, secure, and fit for the future.

Our commitment to delivering resilient, secure, and reliable critical connectivity solutions is demonstrated in our work with Thames Water. As specialists in highly regulated markets, we provide the expertise, products, and support needed for mission-critical and life-critical applications. Our partnerships with leading organisations like Vodafone Business allow us to deliver best-in-class solutions tailored to the specific needs of large-scale infrastructure projects.
