River health
We know people love our rivers. We rely on them and their groundwater sources for safe, clean drinking water.
In serving 16 million people, we face many challenges. It's our responsibility to treat wastewater safely before returning it to rivers. We understand our impact and take river and groundwater health seriously.
This includes:
- Our partnerships to improve the water environment, including our catchment approach
- Sharing our environmental data, like real-time storm overflow information
- Our current and future investment plans to reduce storm overflows
- Ways to enjoy rivers and nature in the Thames region
- Our approach to managing surface water in urban areas
