Protecting the River Thames
The River Thames is our most important water source. It's our responsibility to protect it as the UK's largest water supplier.
We're investing £4.5 billion with the Thames Tideway Tunnel. The tunnel will help reduce combined sewer overflows and decrease sewage spills. It will also provide habitats for a range of aquatic wildlife.
