Tideway London Revenue and Competitors

Tideway is 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 also contravenes the European Urban Wastewater Treatment Directive. London's sewerage system relies on an integrated network of combined sewer overflows (CSOs). At the time it was built, the CSOs would release flows through discharge points along the river during heavy storms. Originally, this would happen once or twice a year, it now happens on a weekly basis and no longer requires a storm to trigger overflows. By intercepting the sewage before it enters the river, the Thames Tideway Tunnel will help prevent the tidal River Thames from being polluted with untreated sewage which can stay in the river for up to three months before the ebb and flow of the tide finally takes it out to sea.
