Labour disarray as Khan backs cleanup at site of Thames sewage plan

Labour appeared to be in disarray yesterday over ambitions to clean up the River Thames for swimming.

The mayor of London, Sadiq Khan, announced ambitions to prioritise an area of the river in Teddington, south-west London, to make it safe and clean for swimming as part of a new 10-year strategy to reduce pollution in the river and encourage people to spend time in and around it.

Supporting Khan as he made the announcement was the environment secretary, Steve Reed. But Reed just last week approved the next stage in the development of a controversial scheme to allow Thames Water to pump 75m litres a day of treated sewage into the river at the same spot in Teddington.

Environmental campaigners have raised a number of concerns, such as damage to river systems from the increased water temperatures caused by pumping treated sewage into the river during low flow, a change in the salinity of the river, and the impact on fish and biodiversity. The Teddington scheme will have to go through development consent where environmental concerns will be considered before it is fully approved.
