The 3RiversCleanUp is a 3-week long intensive annual volunteer campaign to improve
South East London’s rivers.
Take your family, your friends or just yourself on an urban wilderness adventure in South East London. For three weeks this summer you can join in a unique series of family-friendly days on your local river; from clean-ups to free our precious rivers of harmful litter, wildlife habitat improvements to pond dipping and nature walks suitable for all ages.
Now in its fifth year, this unique partnership programme has been highly successful in
removing and preventing the spread of Himalayan Balsam in the Ravensbourne River catchment. With this invasive species a little more under control, this year we can broaden our focus to include other issues such as litter, and habitat regeneration.
Last year, 500 volunteers got involved, with a total of 1542 work hours spent cleaning up and managing the river network! This year, we are relying on a similar show of strength. Thames21 will help lead a series of volunteer events from June 17 to July 7 in collaboration with a number of key organisations. These hands-on volunteering opportunities will take place throughout the Ravensbourne river system; the rivers Ravensbourne, Pool and Quaggy which flow though the South East London boroughs of Lewisham, Greenwich, Croydon and Bromley.
The 3RiversCleanUp is a chance to:
- Get to know your local river

- Discover hidden green gems on your doorstep
- Help your local environment
- Meet like-minded people
- Learn about local wildlife and the river system
