This study focuses on a value-added function to StormPav Green Pavement System, that is not only designed to store stormwater but to act as a conduit to drain stormwater in a typical commercial environment. This system is a form of permeable road, in which multi-unit small chambers are used to overcome the problem of big stormwater storage structure; and at the same time could provide a greater strength in its interlocking manner for vehicles transportation. This structure is analysed of its capability to store and convey stormwater from roof and road catchments that is subjected to 10-year ARI design rainfall with durations ranging from 5 to 180 minutes. The added function could only be executed when appropriate inlet and outlet design are decided. Computer models are incorporated in this study. Comparison of Storm Water Management Model (SWMM) and SolidWorks Flow Simulation (SWFS) models is performed. Results show that both models are reiterating each other, suggesting that the confidence level of the model verification is enhanced. Visualization of flow within the system is also demonstrated. Results indicate that inlet and outlet design sizes of 100 mm and 190 mm x 700 mm respectively could provide optimum filling, ponding and draining effects. The system is able to reasonably alleviate the peak discharges at the outfall. Besides that, by comparing with conventional drainage system, the discharge reduction after implementing the StormPav system reports the highest reduction in discharge (approximately 80% reduction) occurred for the 5-minute design rainfall duration, while the lowest reduction in discharge (approximately no reduction) occurred for 180-minute design rainfall duration. This means that the structure has reached its limit or range of service. In conclusion, findings show that the StormPav system has demonstrated the capability of conveying and storing stormwater up to 180-minute, 10-year ARI design rainfall.
