Only Severn Trent and Wessex Water achieved the highest level of performance, with 4 star ratings from the EA. No river in England was found to be in a good overall state, amid concerns over the scale of sewage discharges and agricultural and industrial chemicals entering the water system. In March, Southern pleaded guilty at Maidstone crown court to 51 charges brought by the EA of dumping poisonous, noxious substances including raw sewage, after a criminal inquiry that ran alongside the Ofwat investigations. Earlier this year, Southern Water pleaded guilty to 51 charges brought by the agency after a criminal inquiry that ran alongside the Ofwat investigations. That is not good enough.
