Integrated SuDS Systems

Combining sustainable drainage, urban greening and engineered infrastructure within coordinated landscape systems.

GreenBlue Urban provides integrated SuDS infrastructure and technical guidance for streets, developments and public spaces, helping drainage and planting systems work together effectively within urban environments.

The Challenge

Managing surface water within urban environments increasingly requires drainage infrastructure that can integrate alongside streets, planting and public realm design.

At the same time, many projects are seeking to increase urban greening, biodiversity and tree cover within constrained development sites.

Delivering these objectives together can present several challenges:

Limited space for drainage infrastructure

Constrained underground space for SuDS

Restricted soil volumes and planting conditions

Coordinating drainage with landscape requirements

“Integrated SuDS systems allow drainage, planting and urban infrastructure to work together within the same coordinated landscape strategy.”

Designing Integrated SuDS Systems

Integrated SuDS systems combine drainage infrastructure, planting systems and engineered landscape components within coordinated site designs.

Depending on project requirements, this may include SuDS tree pits, rain gardens, integrated planters and structural soil systems working together across a wider drainage strategy.


Key benefits can include:

Surface water attenuation and runoff reduction


Integrated urban greening and biodiversity benefits


Improved resilience within streets and public spaces


Flexible solutions for developments and retrofit schemes


Enhanced public spaces and wider amenity value within urban environments


When designed effectively, these systems help support both surface water management and long-term landscape performance.

Technical Guidance and Coordination

Integrated SuDS systems often require coordination between drainage infrastructure, planting design, highways requirements and wider public realm layouts. Delivering successful schemes depends on ensuring these different elements work together effectively within constrained urban environments.

GreenBlue Urban provides practical technical guidance to help project teams integrate SuDS infrastructure within streets, developments and public spaces. This may include coordination between planting systems, drainage components and surrounding urban infrastructure.

Infrastructure Used in Nature-Based SuDS

Delivering nature-based SuDS relies on a combination of landscape, soil, planting and engineered components that work together to manage surface water close to where it falls. This can include raingardens, SuDS tree pits, modular attenuation planters and engineered soil systems designed to support infiltration, attenuation, treatment and healthy vegetation growth. Together, these elements help slow, store and treat runoff while creating greener, more resilient places.

SuDS Tree Pits

Tree pits, such as ArborFlow, that combine stormwater management with healthy urban tree growth.

Raingardens

Planted SuDS features, such as HydroPlanter that capture, slow and treat surface water runoff.

SuDSPods

Modular planter-based SuDS units that provide compact attenuation and rainwater reuse options.

Engineered Soil

Specialist soil that supports planting, water movement and pollutant filtration.
