Raingardens & Planters
Visible SuDS systems - adding amenity, biodiversity and compliant stormwater performance.
Why raingardens and SuDS planters matter
Rainwater runoff can be managed at the surface as well as below ground. Raingardens and planters detain flows visibly, improving water quality, supporting vegetation and creating attractive public realm.
Both solutions offer predictable SuDS performance while enhancing streetscapes:
- Capture and filter runoff at source.
- Deliver controlled discharge in line with authority requirements.
- Add amenity and biodiversity value alongside hydraulic function.
Why choose GreenBlue raingardens and planters
- Proven systems – Already installed in streets, schools and regeneration projects across the UK and Europe.
- FLL and ZTV aligned – Compliant with German standards for infiltration, detention and controlled outflow.
- Sustainable Build – Manufactured from recycled materials with EPD verification.
- Straightforward Specification – Supported by CAD, BIM, calculators and technical guidance.
- Visible Performance – Systems designed to demonstrate SuDS function clearly on site.
HydroPlanter – modular raingardens
Pre-fabricated units that create planted basins with engineered soil, underdrains and overflow routing. HydroPlanters integrate easily into streetscapes, providing both stormwater attenuation and urban greenery.
- Capture runoff from hard surfaces.
- Filter and detain flows in engineered soil media.
- Enhance biodiversity and amenity in visible planting.
SuDSpod – SuDS planters
Compact, modular planters with internal storage, engineered soils and controlled discharge. SuDSpods are ideal where space is constrained or underground utilities restrict excavation.
- Accept runoff via kerb or surface inlets.
- Provide storage and filtration within a planter footprint.
- Release flows at a throttled rate or via infiltration
Where these solutions fit
- Dense urban streetscapes with limited excavation depth.
- Retrofit schemes needing surface-based SuDS measures.
- Public realm projects requiring visible amenity and biodiversity.
- Authority-led schemes with predictable, compliant discharge requirements.
Case studies
GreenBlue raingardens and planters are proven on projects across Europe — delivering cleaner runoff, added biodiversity and healthier, climate-resilient urban places. Examples include city-centre retrofits and school projects where visible SuDS performance was required.
