Outflow water quality of Hydrapave permeable paving

The use of permeable paving originated in Europe in the early 1980’s and has subsequently gained international acceptance including widespread use throughout Australia. Originally used as a means of flood mitigation, recent emphasis on water shortages within Australia have resulted in permeable paving being considered as a system for water harvesting and subsequent water re-use. Outflow water from tanked permeable paving systems is now being considered for use in non potable applications including gardening and flushing of toilets. This paper reviews the current installation methods and material properties usually specified for permeable paving and considers their role in the mitigation of pollutants contained in the discharge water. With the ever increasing use of permeable paving in streetscapes, parks and gardens, several studies of discharge water from Hydrapave™ paved areas are examined. The content of hydrocarbons and heavy metals present in the outflow water are compared to industry benchmarks with the results indicating that Hydrapave™ outflows compare favourably as well as providing superior performance in the control of pollutants compared to other paved systems.
