Thames Water was hit with a multimillion pound fine for flooding a park and polluting a rare chalk stream with 79 million litres of untreated sewage sludge.
The water firm was fined £4 million at Aylesbury Crown Court after pleading guilty to the pollution incidents, which took place near its Hogsmill sewage works between 2016 and 2019 in Kingston, south west London.
The firm was prosecuted by the Environment Agency for a number of incidents. Around 27 January, sewage sludge was discharged from Hogsmill sewage treatment works into Hogsmill River. Between 13 and 16 October 2018, raw untreated sewage and sewage debris was discharged onto Green Lane Recreation Ground and into California Road Ditch and Hogsmill River via manholes.
