Thames Water has been fined £2.3 million after a stream was polluted by sewage. A court heard failure to address equipment faults at a sewage-treatment plant in Oxfordshire made the incident “entirely foreseeable”. Sewage with high levels of ammonia was released into Fawley Court Ditch at Henley-on-Thames in 2016, killing 1,144 fish and other water life. Poor management at the plant was laid bare at Aylesbury Crown Court. Thames Water’s treatment works at Henley had no adequate monitoring in place to manage the risk of pollution, made worse by staff not responding to alarms highlighting faults in the process. Judge Francis Sheridan said Thames Water should have reacted to the warnings “long before” they did. He added the pollution and the events leading up to it showed “high negligence” by the company.
