Aquaflow permeable paving sustainable urban drainage systems
The Solution - Source Control Sustainable Urban Drainage Systems (SUDS) are increasingly being used to prevent run-off and flooding, and as a method of collecting and cleaning storm water.
The sustainable urban drainage system, designed and manufactured by Formpave and available from Hardscape allows heavy rain to infiltrate through a permeable concrete block paved surface into a unique sub-base before being released in a controlled manner into sewers or water courses. Discharge rates in accordance with greenfield run-off can be readily achieved if required. Alternatively, if the underlying sub-grade is suitable the water can be infiltrated directly into the sub-grade.
The water leaving the Aquaflow system is cleaned by filtration and microbial action and can be used for secondary non-potable uses such as flushing toilets and watering soft landscaping.
A further advantage of the system is that roof water can be drained directly into the sub-base via a rodable sump, or if siphonically drained, through a dispersion chamber.
