Southern Water Tech Stack
Water and wastewater utility serving 6M+ customers across South East England
Southern Water operates critical water and wastewater infrastructure for the South East, distributing 532M litres of drinking water daily and treating 717M litres of wastewater. The tech stack reveals a hybrid organization: industrial control systems (Rockwell, SCADA, PLC) anchor legacy operations, while cloud infrastructure (Azure, Terraform, ARM) and BI tools (Prism, ArcGIS) signal digital modernization. Engineering-heavy hiring (75 roles) focused on mid-to-senior levels, combined with active projects around asset management and storm overflow reduction, points to infrastructure renewal rather than growth—a utility under regulatory and climate pressure managing aging systems.
