Sustainable Drainage Systems (SuDS) mimic natural drainage patterns and seek to manage rainfall close to where it falls.
The benefits of SuDS include:
- reducing the risk of flooding by slowing down surface water runoff and providing storage
- reducing surface water pollution by treating runoff through natural processes
- providing natural habitats for wildlife
- providing areas of amenity
Examples of SuDS include:
- Water butts
- Green roofs
- Rainwater harvesting
- Wetlands and reedbeds
- Balancing ponds or detention basins
How Sustainable Drainage Systems are designed
Early consideration of the movement of water is crucial to the success of SuDS and allows developers to maximise benefits.
If you are a developer, designer or consultant and want to know how to integrate SuDs into the master planning of small and large developments, our SuDS masterplanning document will complement guidance on SuDS design for different types of developments.
