This SUDS’ solution combines a "soil permeable system" with a "flat conduit pavement" made with new materials. The system is able to emulate the natural hydrological cycle, capturing the rainwater as much as possible to where it falls, filtering it, and channeling the resulting subsurface drainage - through "drainage cells" or flat conduits - to suitable sites where to be stored, treated or recharged. In doing that, the system reduces the pollution of urban runoff fluxes, and the requirements of water for gardening.
