Could Porous Pavements be Part of the Urban Water Solution?

(2006 – current)

Urbanisation degrades waterways by stormwater pollution and unsustainable demands on water resources.  There are few opportunities in densely urbanised areas for treating or harvesting stormwater.  One technology with potential is replacement of impervious areas with porous pavement. Yet concerns over clogging have limited the application of this technology in Australia.

Laboratory and field experiments could enable us to better understand clogging, thereby improving design and maintenance of porous pavements, providing confidence for porous pavements to become part of a solution to the urban water problem. Australian companies, such as Permapave and Hydrapave, are developing solutions to clogging that involve testing for long-term efficiency and reliability.

By refining design of innovative porous pavement technologies, the project will benefit Australia’s sustainable water technologies’ industry in a burgeoning market, while meeting demands of a growing population. Studies comprise experiments with real and compressed time scales; assessment of how biological growth affects treatment; laboratory testing of monolithic porous pavement designs; and field investigations into modelling methods.
