Welcome to Thames21

We believe that putting healthy rivers back at the heart of community life is the key to reconnecting people with nature and each other.

In today’s modern world, waterways are often overlooked or unloved by the sometimes isolated and stressed communities that surround them.

Our aim is to rebuild the relationship between communities and their rivers; restoring their health and vibrancy and boosting wellbeing and community cohesion in the process.

Rivers, canals and stretches of open water are the perfect antidote to urban living – which is one of the key reasons thousands of volunteers help us rewild and protect them every year.

We focus on delivering Environmental Improvements, Education, Research and Advocacy work across the capital to achieve our goal.

From our popular Love the Lea project and outdoor classrooms on the River Brent, to monitoring the water quality of the Thames and becoming a guardian of your local river with our accredited training programme, we offer engaging and inspiring ways for you to get in touch with your local river.

Feeling inspired?  

If you don’t see an event on your local waterway or have a suggestion for work you would like to see us doing, let us know.

We have many exciting events throughout the year, brought to you in partnership with others.

One is the Three Rivers Clean Up, now in its 9th year, an intensive campaign to improve South East London’s rivers, from June 3 to June 24.
Another is London Rivers Week, a series of walks and talks to celebrate London’s rivers, run in partnership with the London Rivers Restoration Group, from June 26 to July 2, 2017.
