In London, the Long Wait for a Super Sewer Is Almost Over

The Tideway Tunnel, a £4.5 billion project in London, is nearing 90% completion and aims to significantly improve the Thames River's water quality by redirecting raw sewage and runoff to treatment plants. This "Super Sewer" will address overflows from the city's 150-year-old wastewater system. Despite its environmental benefits, the project has faced financial challenges and public scrutiny over increased water bills. The tunnel represents the most significant upgrade to London's sewage system since the 1865 opening of the Crossness Pumping Station.
