Support Us

Rivers are the beating heart of our land but they are in peril. Suffering from a tide of plastic pollution, packaging and sewage, our rivers have been hidden, misused and ignored.

We are changing that by putting rivers healthy back at the heart of community life. Our river improvement projects invite people like you, who live or work near them, to get involved and make those enhancements sustainable.  

With more than 400 miles of river and canal in London, that’s roughly the length of Brighton to Edinburgh, we have our work cut out and need your support!

Donate now to give your rivers some TLC and bring them back from the brink.
