In urban landscapes, concrete and other impermeable surfaces, together with the removal of vegetation, result in increased surface water run-off.
The growing trend to pave our driveways and front gardens allows rainwater to be quickly directed into the drainage system, which during heavy rain and storms can cause local flooding.
Rainwater gardens are landscaped areas, designed to help slow down surface water run-off, reducing the rate at that it enters the surface water drainage system. In turn, this helps to reduce the risk of flooding.
Rainwater gardens were first developed in the United States in the 1990s and it is a popular approach for flood prevention.
We compiled a handbook to help you create your own rainwater garden. As well as helping to prevent flooding, rainwater gardens can make attractive features in front or rear gardens that can also benefit wildlife and attract bees and other pollinating insects.
