Abstract

This project explores the potential of a specific type of natural-based decentralised wastewater treatment solution in a fast-growing area: Campbelltown local government area (LGA), Sydney, with a focus on experimental design based on different densification scenarios and centralisation level of treatment scheme. The analysis and design are carried on for three scales: Greater Sydney area, Campbelltown LGA, and two samples sites in the city centre of Campbelltown LGA. for Greater Sydney area, the design is revealed as a long-term and all-rounded proposal; for the main city centre of Campbelltown LGA, the design focuses on the redevelopment and functional division of its main water bone Bowbowing Creek to serve as a treatment media. In order to experiment the schemes in detail, Leumeah centre and Campbelltown centre are designed with 6 scenarios (2 densification scenarios x 3 levels of treatment centrlisation) for each site.

The results are evaluated with the same criteria, which reveals the feasibility, pros and cons of each scenario while confirming the possibility of implementing decentralised wastewater treatment in this area although it does not bring out the same performance for all the scenarios. Further research can be carried out to simulate the long-term performance of the schemes and to test the performance with different technical components of DEWATS for the locations.
