Sustainable Drainage Systems
5. Sustainable Drainage Systems
Site developments and hard landscaping can result in areas where there is localized flood risk in the event heavy rain, contamination as a result of spillage or water course depletion in the event of dry weather.
Sustainable drainage solutions aims to mimic as closely as possible the natural drainage of a site and minimise the impact of urban development on the flooding and pollution of waterways.
Generally these techniques use vegetation features to treat pollution and slow down or reduce flows as well as enhance the landscape and provide improved wildlife habitats.
