Tideway are upgrading London’s sewerage system to cope with the demands of the city well into the 22nd century.
After years of study, construction work for the new 25 kilometre interception, storage and transfer tunnel running up to 65 metres below the river, known as the Thames Tideway Tunnel, will start in 2016.
Starting in west London, the main tunnel generally follows the route of the River Thames to Limehouse, where it then continues north-east to Abbey Mills Pumping Station near Stratford. There it
will be connected to the Lee Tunnel, which will transfer the sewage to Beckton Sewage Treatment Works.
Overflows of untreated sewage into the tidal River Thames add up to tens of millions of tonnes every year. This is unacceptable and the Thames Tideway Tunnel will clean up one of the world’s iconic rivers.
