Communities across south-east England are filing the first coordinated legal complaints that sewage pollution by Thames Water negatively affects their lives.

Thames Water failed to complete upgrades to 98 treatment plants and pumping stations which have the worst records for sewage pollution into the environment, despite a promise to invest in them over the last five years.

People in 13 areas including Hackney, Oxford, Richmond upon Thames and Wokingham are sending statutory nuisance complaints to their local authorities demanding accountability from Thames Water and urgent action.
