Thames Tideway Tunnel

Investing in river health

We're investing £4.5 billion pounds as part of a long-term, strategic scheme to improve river health. The Thames Tideway Tunnel will help to:

• Reduce combined sewer overflows in a typical year by 95% into the tidal river Thames
• Provide habitats for aquatic wildlife
• Collect sewage so it can be treated before entering the river
• Decrease sewage spills and sewage-related litter
