Abstract: Water is a scarce resource in Australia and the conservation and re-use of stormwater runoff is often an important consideration in supplementing municipal water supplies. Permeable interlocking concrete paving (PICP) is an innovative technology that provides the ability to either infiltrate stormwater on-site through the underlying subgrade materials, or to harvest stormwater for fitfor-purpose reuse using geomembrane sealed subsurface ‘tanks'. Permeable pavement installations are becoming an increasingly prevalent stormwater management tool for local authorities. However, one of the main concerns for designers is the perceived limited lifespan of these systems due to clogging by sediments and other detritus materials. This paper reviews contemporary research literature on the clogging processes of PICPs and examines the various methodologies used to conduct the research. The results of the critical review were the main driver for the design of a new experimental research project being undertaken at the University of the Sunshine Coast (USC). The aims of this study are to assess and quantify the long-term performance of PICPs in reducing stormwater flows and pollution loads and to improve understanding of the clogging processes that take place in PICPs under typical Australian rainfall and runoff conditions.
