Thames Tideway Tunnel

The Thames Tideway Tunnel is a major infrastructure project in London designed to improve the city’s sewage system. It involves constructing a 25-kilometer (16-mile) underground tunnel to reduce overflow from the existing sewage network during heavy rainfall. This overflow can lead to untreated sewage entering the River Thames, which is harmful to the environment and public health. The tunnel will capture and store excess sewage, allowing it to be treated properly, ensuring cleaner water in the river and reducing pollution. The project aims to support London’s growth and protect its natural waterways for future generations.
