Rain gardens are being created by communities in south-west London to help retain rainwater – improving resilience to both flooding and drought.
Wandle Rain Gardens, a project by the London Wildlife Trust, empowers communities living along the course of the River Wandle to create green landscape features which can help retain rainwater, and so improving the communities’ resilience to flooding and other impacts from climate change.
A rain garden is a shallow area of ground or dip which receives run-off from roofs and other hard surfaces. It is planted with plants that can stand waterlogging for up to 48 hours at a time. More drought-tolerant plants are used towards the edges.
London Wildlife Trust is helping local people around the area of the Wandle Valley Regional Park – in Wandsworth, Merton and Sutton boroughs – to help people make practical adaptations in their gardens and community spaces by diverting rainwater away from drains – both saving water and reducing pressure on the sewage system.
This is done through the use of Sustainable Drainage Systems (SuDS) that create natural features to store rainwater such as rain gardens, green roofs and water butts.
