There’s been a sewage leak in a river which runs through Wimbledon Common, Richmond Park and Barnes Common.
Posting on X, the Wimbledon and Putney Commons group says people and dogs should keep out of Beverley Brook.
Thames Water says;
“Our teams are working to repair a burst rising main in the area, and we are using tankers to ensure no further discharge. An assessment of what mitigation measures need to be carried out will take place shortly.”
