HydroPlanter Flex

Flexible Raingarden System

Building on the enthusiastic reception and adoption of our HydroPlanter rain garden system, and in response to calls for more extensive rain gardens and flexibility of shape, GreenBlue Urban are excited to launch the first fully integrated rain garden system – the HydroPlanter Flex!

Rain gardens are increasingly chosen as a best practice option, supporting the four pillars of SuDS (water quality, water quantity, amenity, and biodiversity) due to being cost efficient and highly effective. Simple to retrofit into highways schemes and ideal for new developments of any size, the HydroPlanter Flex cuts the complexity and unknowns out of design and installation.

Whilst being simple to design and adapt to site constraints, this system is the perfect solution for engineers, contractors and housebuilders required to meet regional SuDS regulations.


  • Cuts complexity in specification, design and installation
  • Low maintenance
  • Reduces flood risk
  • Nature-based water cleansing
  • Delivers improved amenity values
  • Enhanced biodiversity with green infrastructure


  • All required components within the rain garden are supplied in a single system
  • In-house design and installation support service
  • Fully modellable
  • Exceedance Chamber for overflow and inspection/maintenance
  • Full design/specification support for architects and drainage/SuDS engineers
