Water companies in England face outrage over record sewage discharges

Call for environmental emergency to be declared after data reveals 105% rise in raw sewage discharges over past 12 months

• How polluted is your local river and which regions are worst hit?

Water companies in England have faced a barrage of criticism as data revealed raw sewage was discharged for more than 3.6m hours into rivers and seas last year in a 105% increase on the previous 12 months.

The scale of the discharges of untreated waste made 2023 the worst year for storm water pollution. Early data seen by the Guardian put the scale of discharges at more than 4m hours, but officials said the figures were an early estimate.
