Reducing runoff and treating stormwater with no sub-surface drainage required ⛈ 🚗 🌳 Last week the Porous Lane team completed a 430m2 section of WSUD carpark for Glen Eira City Council at the East Caulfield Reserve in Melbourne's South East. Porous Lane's permeable pavement will reduce runoff from the parking bays and improving stormwater quality, while recharging the groundwater table to provide passive irrigation to the established trees. The trafficable surface will also be able to tolerate future tree root movement without cracking. Other benefits include a lower surface temperature than asphalt and the re-use of over 1200 waste tyres. This carpark is a great example of a system that does not require any sub-surface drainage due to the high permeability of the subgrade. Water is captured in storage cells beneath the surface then drains out of the system at a slower rate, returning rate back to the groundwater table after treatment via the Porous Lane medium. We would like to thank Boris Petrovski at Glen Eira City Council, Dale Browne and E2Designlab for the design work, Parkinson Group, and in particular, Angus Burnett for their assistance with the installation and recognise the contribution of Melbourne Water to the project.
