The Thames Tideway Tunnel

The Thames Tideway Tunnel is a major wastewater project in London designed to reduce pollution and improve water quality in the River Thames. It’s a large underground tunnel, around 25 kilometers long, built beneath the river and its surroundings. The tunnel captures and stores overflows from the city’s combined sewer system during heavy rains, preventing them from flowing directly into the Thames. When completed, it will help protect the river’s ecosystem, improve sanitation, and ensure cleaner water for communities and wildlife. The project addresses London’s aging infrastructure and aims for a more sustainable and resilient urban environment.
