A1.1
Create high quality Sustainable Drainage Systems (SuDS) to reduce storm overflows, support ground water quality and encourage groundwater recharge/ infiltration where required.
Aquifers
Support aquifer health
Various types of SuDS depending on purpose:
・Swales and conveyance channels.
・Filtration.
・Infiltration.
・Retention and storage.
・Wetland, inlets, outlets and control structures.
Specific examples include:
・Green roofs.
・Permeable paving.
・Rain gardens.
・Tree planting.
・Swales.
・Ponds.
・Infiltration basins.
・Soakaways.
Widespread but only in areas suitable for creation of SuDs - dependent on factors such as:
・Underlying geology.
・Proximity to Ground Water Source Protection Zones (where SuDS may risk contaminating water resources).
・Topography.
・Flood risk.
・Archaeology.
・Landscape etc.
See maps identifying local ‘SuDS Suitability Scores’ for information.
