HydroPlanter - GreenBlue Urban
Close this search box.


We are excited to announce the launch of a new, modular, bioretention rain garden system. The HydroPlanter is a stormwater management solution that can be retrofitted into highways schemes and on new developments of any size.

This is a ‘plug and play’ sustainable urban drainage solution (SUDs) that can attenuate and cleanse storm water and provide amenity and biodiversity to new and existing spaces. The modules will be filled with a particular soil specification and planted wildflowers and biodiverse grasses.

The concept is flexible, scalable and each unit stacks together to be a convenient solution that any subcontractor can work with and install. Installation is fast, simple and offers significant savings to alternative methods.

The modular characteristics with pre-calculated hydrological performance statistics mean that specification and design is very simple for any given catchment area.



  • Stormwater attenuation storage
  • Excellent amenity and biodiversity values
  • Installation speed and simplicity
  • Ease of specification and design
  • Cost effectiveness
  • Freeze/thaw resistant system


  • 100% recycled materials
  • Slot-together modules
  • Optional exceedance flow drain point
  • Stack-able design for transport efficiency

Catchment area Catchment area per module for each UK region has been calculated and is viewable on the downloadable datasheet.
Infiltration The HydroPlanter works as a fully lined system not allowing infiltration, so no further lining of the excavation is necessary. If infiltration is required, GBU can provide adapted HydroPlanters to suit.
Utilities Utilities can be simply worked around – review details on the downloadable datasheet.
Stock holding Large stocks are held in the UK for immediate despatch.
Pollution removal indices (CIRIA SuDS Manual – Bioretention System) TSS: 0.8 – Metals: 0.8 – Hydrocarbons: 0.8
