Case study

World’s biggest recycled water facility in the basement of a residential building.

Basement collection, treatment and reuse of high wastewater in a high density urban development. A decentralised recycled water system has been delivered within a 5.8ha mixed use high density infilll development site in Sydney. Wastewater is collected from precinct buildings (residential, commercial and retail) and an adjacent public sewer with top-up from stormwater runoff and rainwater. Wastewater is treated to the highest Australian standards for recycled water using a membrane bioreactor (MBR) and reverse osmosis (RO). The recycled water is distributed within the precinct to supply water for cooling towers, irrigation, toilet flushing and washing machines. The scheme will also be exported across the road to University of Technology Sydney once the infrastructure (under construction at the time of writing) is completed.
