Green Square Town Centre in South Sydney is a project that is powered by an ecological engine that produces (and feeds from) recycled storm water & renewable energy. The firm of Landscape Architects, Mcgregor Coxall worked with the clients — City Of Sydney Council and Landcom — to devise the system. According to the firm: “The water harvesting system intercepts polluted storm water from the 250 ha upstream urban catchment that flows directly beneath the town centre in a concrete pipe. This water is diverted to the surface and into the park and urban stream where it is cleaned through biofiltration. Water from the plaza and surrounding roads are also diverted into the filtration media. The water is then collected for storage.”
The project provides ecological services by improving the quality of the Canal and Bay downstream. The rest of the non potable water is further naturally filtered and stored in the tanks where it is available for reuse. Mcgregor Coxall states that: “…the ecological engine will provide 90% of the water needs of the entire project including all the residential and commercial uses. The urban stream rises and falls in response to rainfall in the catchment while flood water is diverted under the site in in extreme events.” For more information visit the rest of the article HERE.
The town located on contaminated industrial land would be powered by an ecological engine that delivers recycled storm water and renewable energy to the project. The master plan exploits the area’s hydrological system to meet the water needs. Polluted storm water from an upstream urban catchment is directed through a pipe for bio-filtration. The filtered water is then stored in tanks for usage.
The project exhibits a coherent array of hydro-logically symbiotic systems such as: 1. Stormwater diversion from culvert | 2. Biofiltration cells in urban stream | 3. Urban stream & pond system | 4. Filtered water holding tanks | 5. Harvested roof water | 6. Water feature circulation | 7. Non-potable water supply to buildings | 8. Filtered excess water to culvert
