SEAMLESSLY INTEGRATED WATER MANAGEMENT

The four wetlands were constructed over time to capture stormwater in order to improve water quality and provide flood mitigation and amenity. However, the amount of water lost due to evaporation and lacking sustainable water supply have caused problems for the aquatic environment.

Engineers, ecologists and landscape architects were urged to provide a solution where stormwater management infrastructure is seamlessly integrated into the landscape design in a large scaled park space. The design aimed to create a continuous natural edge blending into the existing periphery of wetlands and conceal the curving concrete retaining wall from a distance.

Gabions, filled with locally resourced sandstone and recycled materials were chosen to build on top of concrete to create a natural look and to accommodate stormwater volumes in a confined space. The distinctive use of recycled brick gabions not only added another habitat overlay to the design proving an ecological function but also recalled past histories of the former industrial land.

The Sydney Park stormwater harvesting stage 1 project is due for completion in a few weeks, and we are looking forward to seeing the transformation of these wetlands into a sustainable green infrastructure.

Permathene Galfan Plus architectural gabions were specified for this project.
