Analysis by campaign group finds utility company had highest rate of ‘no-flow’ samples of any water and sewerage firm in 2024

The water firm Anglian Water passed thousands of pollution tests at its sewage plants that were never carried out.

Operational data reveals how more than 6,000 pollution tests from 2015 to 2024 could not be carried out under a controversial self-monitoring regime because it was reported there was no outflow of treated sewage from the plants.
