Climate Change is the single biggest risk to the Wandle’s natural heritage and evidence of this is becoming more apparent. Altered weather patterns are leading to increased drought and flooding in the Wandle Valley.

The Wandle Rain Gardens project is being delivered throughout 2017 by the London Wildlife Trust and builds on the success of their previous “Lost Effra” project completed in the Borough of Lambeth.

The aim of this project is to empower local communities living along the coarse of the River Wandle to create green landscape features that help to retain rainwater – improving resilience to both flooding and drought!

The team will work with local people across Wandsworth, Merton and Sutton boroughs, to create rain gardens that raise awareness of the local threats posed by climate change, as well as the likely impacts on the Wandle itself. This is a crucial step towards sustainability given that by 2020 the deficit of water in London is projected to be 133 million litres per day and by 2040 this will increase to 416 million litres per day.

Gardens and community spaces will undergo practical changes to re-naturalise the urban environment and divert rainwater away from drains – both saving water and reducing flood risk. Sustainable Drainage Systems (SuDS) will be used which create natural features to store rainwater, such as rain gardens, green roofs and water butts.

If you are interested in volunteering to help the project or know of a community space that would be interested in hosting a Wandle Rain Garden please get in touch with Joanna Ecclestone at or call on 020 7252 9186



This project is part of the wider Living Wandle Landscape Partnership Scheme, funded by the National Lottery through the Heritage Lottery Fund.
