The construction of the "Thames Tideway" tunnel, a super sewer aimed at reducing pollution in the River Thames, has been completed near the capital of Great Britain, reports a correspondent from Kazpravda.kz citing Naked-Science.
The need for new sewage systems arose because the sewer built 150 years ago by Sir Joseph Bazalgette had become outdated and could not handle the large volume of London’s waste, which was regularly discharged into the Thames.
Construction began in 2016 at 24 sites across London and was completed in early 2025.
The facility has been fully integrated into London’s Victorian sewage system. The length of the super sewer is 25 kilometers. The diameter of its main tunnel is 7.2 meters, which is equivalent to three London double-decker buses, while the diameter of the connecting tunnels ranges from two to five meters.
Thanks to the new system, the equivalent of 2,200 Olympic-sized swimming pools of wastewater has already been prevented from entering the river.
