Teddington Direct River Abstraction Scheme

The Teddington Direct River Abstraction (TDRA) scheme plans to provide up to 75 million extra litres of water per day during times of prolonged dry weather.

During droughts, Thames Water (TW) plan to take water from the Thames using a new intake located upstream of Teddington Weir. The water would then be transferred via a new underground tunnel to their existing Thames Lee Tunnel (TLT), which connects to the Lee Valley reservoirs. To keep river levels balanced, TW would replace the water taken at Teddington with the same amount of recycled water from their proposed new Tertiary Treatment Plant at Mogden Sewage Treatment Works.

The Statutory Consultation is now up and running until 26th August 2025. Please see their consultation page for links to have your say. A Teddington Information Event is taking place on 17th July at The Lensbury, and there are others.

Save Our Lands and River (SOLAR) are leading the opposition - see here for their views. SOLAR do not advise using the TW feedback questionnaire as it does not give people a chance to reject the scheme overall. Rather, they suggest responding by email or post.
