The South Creek catchment is the hottest, driest and least-treed area of Sydney.
The population of the Western Parkland City, which is largely located in the catchment, is expected to increase to 1.5 million people by 2056.
The increase in population and related development could potentially create an urban heat island and degrade the local waterways and environment.
A signiﬁcant investment is required to replace and augment water and wastewater infrastructure in this area to service future developments and avoid overwhelming legacy infrastructure.
There is an opportunity to integrate water infrastructure into land use and water cycle planning, which would provide signiﬁcant economic beneﬁt compared with traditional water cycle management approaches.
The initiative is to develop the South Creek Catchment in a way that maximises the opportunity for integrated land use and water cycle planning, to enhance the liveability and environmental quality of the area.
This includes the use of catalytic blue infrastructure (waterways and the facilities that support them) and green infrastructure (assets that incorporate natural vegetation), advanced water cycle management and investment in new or augmented water infrastructure.
The NSW Government is currently investigating different water recycling schemes and applications for both non-potable (for example, irrigation and industrial) and indirect-potable (for example, replenishing groundwater systems) reuse as part of the initiative.
