Rainwater Diffuser

Inlet: - Roof water can be discharged into the porous sub-base with gravity fed drainage it is recommended that the water is fed through a filter chamber into the sub-base adjacent to the paved area. Debris will be trapped for later removal under a maintenance regime. The water is then dispersed within the porous sub-base via a diffuser unit.

Outlet: - The diffuser unit can improve the flow of the stored rainwater from a porous sub-base, when installed prior to a discharge point of a permeable pavement installation.
