WWT London Wetland Centre’s much-loved Rain Garden transformed for a new generation
Originally designed by the late award-winning landscape architect Dr Nigel Dunnett and opened in 2011, the Rain Garden has inspired thousands of visitors to discover how gardens can save water and support wildlife.
Alexia Hollinshead, WWT London General Manager, said:
“We wanted to give our Rain Garden a new lease of life and create a space that is memorable and full of surprises, while showing visitors some of the simple ways we can all help manage rainwater and provide spaces for wildlife to thrive. And what better way to share those water-saving messages than with a talking water butt voiced by WWT Vice President, David Lindo!”
Thanks to funding from BNP Paribas Asset Management through its Empowering Sustainable Futures programme, the Rain Garden has been re-imagined for a new generation.
The garden opened in late September 2026, just in time for WWT’s 80th anniversary celebrations later this autumn and its Wetlands Where You Live campaign.
As heavy rainfall becomes more frequent and intense due to the changing climate, rain gardens have never been more important. Instead of allowing rainwater to rush straight into drains, rain gardens capture it where it falls, slowing the flow and allowing it to soak naturally into the ground. This helps reduce flooding, improve water quality and create valuable habitat for wildlife.
As well as the engaging talking water butt, the Rain Garden provides a sensory experience for all. Visitors can immerse themselves in beautiful planting designed to thrive on rainwater alone, a green roof and cascading water tanks and an interactive interpretation explaining how Sustainable Drainage Systems (SuDS) can help reduce flooding and improve urban environments.
A new map showcases SuDS projects across London, while colourful murals and sensory elements encourage people to explore their own thoughts on rain. There are also a few surprises along the way, including a submerged iconic red London telephone box.
The Rain Garden is included with admission to WWT London and is now open for visitors to enjoy.
