Bluebloqs is a visible, scalable and customisable solution to collect, treat and retain rainwater at building, street or neighbourhood level, making it suitable for uncoupling and aquifer storage and recharge for later use. This highly flexible and prefabricated system integrates bio-filtration technology and flow control in a modular product that can be easily applied alongside the curb in residential areas, in squares, industrial sites and parking lots. The system can be customised to the project specific water quantity and quality requirements.
ProSystem prototype demonstration in operational environment.
Prototype near or at planned operational system. Represents a major step up from TRL 6 by requiring demonstration of an actual system prototype in an operational environment.
Testing plan completed
The testing plan and the BRIGAID’s Testing Innovation Framework (TIF) has been rightly applied and finished. The TRL of the innovation has been effectively reached.
Market assessment completed
A market assessment for this innovation has been completed adequately using BRIGAID’s Market Analysis Framework ( This process has enhanced the strategic skills of the innovator.
The first working prototype system is currently being tested at The Green Village in Delft. We deploy our own large-scale 3D-printer to manufacture the 1:1 components to test the operational aspects of the system. Testing of the treatment efficiency includes the realisation of bio-filtration system in real size with a simulated infiltration well, along with 10 lab columns, which are monitored and analysed using different types of filter media and plant species, with different stormwater volumes and input concentrations.

How does it work?

FLOW CONTROL: With the Bluebloqs system run-off from roofs and streets is retained and slowly discharged, adding capacity to the current sewage system. BIOFILTRATION: Discharged runoff is treated through a combined slow sand filter and a vertical helophyte filter, for removal of sediments, heavy metals, and organic pollutants. CIRCULAR: Bluebloqs performs to optimally use rainwater for deep infiltration, irrigation or suppletion of open surface water. CUSTOMISABLE: The system can be customised in flow rate, filtration capacity, configuration and spatial functions to meet the project requirements. LIGHTWEIGHT: The lightweight prefabricated components enable quick installation on-site.
