Anglian Water has said there is “no room for complacency” after the company was fined £300,000 for a pollution incident in Essex that is thought to have led to the death of more than 5,000 fish. The incident occurred at its Shenfield and Hutton Water Recycling Centre in June 2016. All three pumps in one of the pumping stations at the site were found too have failed following a fire, resulting in untreated sewage pouring out of an emergency overflow into the River Wid.
