Thames Water, the UK’s largest water company was fined £2.3m on Friday for a pollution incident in 2016 that resulted in the death of 1,200 fish and damaged the environment.

The incident, involving a leak of untreated sewage with a high ammonia content into the Fawley Court ditch and stream that flows into the River Thames at Henley-on-Thames, happened between 21 and 24 April 2016.

The prosecution and sentencing of Thames Water, which pleaded guilty to the Environment Agency’s charge was delayed until this week for a number of reasons, including the pandemic.
