In 2020 the Guardian revealed that water firms had discharged raw sewage into England’s rivers 200,000 times the previous year. And in 2021 Ofwat and the Environment Agency announced an investigation into potentially illegal dumping of raw sewage into rivers and coastal waters by water companies.

Water companies are allowed to self-report breaches of permits that allow them to release raw sewage in exceptional circumstances via storm overflows.
