Hanson Aquaflow Permeable Paving


Exfiltration Options
The Aquaflow system prevents run-off and allows water to be released in a controlled manner into the ground below, directed to existing sewer systems or captured and reused for non-potable uses. The following diagrams are to be used as preliminary designs only and should be modified to suit site conditions by a qualified professional engineer.

Water Harvesting
The Aquaflow system can be designed to collect water run-off from surrounding impermeable surfaces. This water is directed into the Aquaflow base where it is cleaned by the Inbitex geotextile before storage. Stored water is then pumped out for re-use in non-potable, exterior uses.
