Southern Water's Pollution Incident Reduction Plan

An overview of the plan

We’re making progress reducing pollution incidents – these incidents have halved over the past five years and last year we had fewer repeat incidents. 

Our 2025 Pollution Incident Reduction Plan (PIRP) shows how we’re tackling pollution incidents over the coming year, as part of a longer-term approach.

The 2025 plan takes a close look at pollution incidents from 2024, analysing the root causes and most effective actions, in the face of challenging weather conditions.
