As a business, it's our responsibility to protect and enhance the environment. 

We rely on natural resources to provide our service. We also want to ensure our communities enjoy rivers and waterways for years to come. So, reducing harmful pollutions is vital for us and our customers.

Improving our impact on the environment is one of our key themes. From river health to sustainable drainage, we're investing in programmes to achieve this.

We also have policies and plans to manage climate change and environmental duties.
