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.
