Innovative SuDS Solutions for Urban Environments
Challenges of Conventional SuDS Systems
Limited Footprint
Insufficient space in dense urban areas for below-ground systems
like tanks, crates, and ponds
2
High Groundwater Levels
Elevated groundwater can compromise the functionality of conventional SuDS
3 Site Constraints
Existing infrastructure and topography can limit the feasibility of traditional SuDS approaches.
Above-Ground Attenuation Options
Detention Basins
Shallow, vegetated depressions that temporarily store and slowly release stormwater.
Swales and Channels
Shallow, vegetated channels that convey and infiltrate surface runoff.
Permeable Surfaces
Porous paving and permeable surfaces that allow water to infiltrate into the ground.
Integrating Above-Ground SuDS
Site Assessment
1
2
Evaluate site constraints, soils, and groundwater levels to determine feasibility.
Design Integration
SuDS planters can be strategically placed along pathways, near building entrances, or in communal areas, serving as both decorative elements and stormwater management solutions.
Multifunctional Benefits
Optimize for stormwater management, amenity, and environmental benefits.
Maintaining Above-Ground SuDS
Vegetation Management
Ensure regular mowing, pruning, and plant replacement for optimal performance.
Inspections and Repairs
Conduct regular inspections and address any structural or functional issues promptly
Sediment Removal
Periodically remove accumulated sediment to maintain storage capacity and infiltration.
User Education
Inform site users about the purpose and proper use of above-ground SuDS features
Benefits of Above-Ground SuDS
Stormwater Management
Effectively attenuate and infiltrate surface runoff, reducing flood risk
Ecological Enhancement
Provide habitat and support for native flora and fauna
Amenity Value
Integrate green infrastructure that enhances the aesthetic and recreational value of the site
Sustainability
Contribute to the overall sustainability and resilience of the urban environment.
