  • What we do
        • Empower communities to look after their local rivers:

          We mobilise thousands of volunteers every year, working along the riverbank to transform neglected rivers into areas that everyone can use and enjoy.

        • Restore the capital’s network of rivers through the power of nature

          We work to clean and green the capital’s 400-mile network of rivers through innovative solutions to boost biodiversity and restore nature.

        • Build a climate resilient London

          We help to build more engaged communities and healthier rivers better able to adapt to the impacts of climate change, now and into the future.
