The Problem
The PSTN switches off on 31 January 2027, and the UK’s mobile operators have already retired 3G. EE will sunset 2G from May 2029, with Vodafone following during 2030, while Virgin Media O2 has already ceased in-bound roaming on its 2G networks. Water utilities that rely on analogue lines for autodialler alarms, SCADA polling, and telemetry at remote sites face a converging risk: lose connectivity to pumping stations, storm overflows, and treatment works at precisely the moment regulatory obligations are increasing.
What’s Inside the White Paper:
A Practical Guide for Water Utility Teams
This 11-page white paper is written for operations, engineering, and compliance teams managing remote water infrastructure. It covers:
- PSTN, 3G, and 2G timelines: which networks are closing, when, and what it means for your estate
- Asset-by-asset risk assessment: pumping stations, treatment works, storm overflows, ancillary sites
- Regulatory context: Environment Act Section 82, CWQM, EDM, and Defra Storm Overflows requirements
- Enforcement case studies: real fines, real consequences, lessons for every utility
- OT security and network segmentation: private APN, VPN, firewall, and Purdue Model alignment
- 90-day migration roadmap: audit, prioritise, deploy, with a clear action plan
- Product solutions: DualCore routers, rSIM failover, and VoiceLink for voice migration
