Abstract

Perth, Western Australia’s largest city is under increasing pressure to implement a more sustainable means of water supply and use. The coastal city is expanding rapidly in both population and geographical size (EPA, 2005), while annual rainfall is variable and gradually decreasing (WC, 2005). On top of the supply issues Perth is continuing to implement a centralised approach to wastewater sanitation, which combines many wastewater streams before treatment and disposal to ocean outfall (EPA, 2005). This creates an open cycle system that has many sustainability issues including inefficient use of potable water supplies, loss of freshwater resources and nutrients, pollution of the receiving water bodies, as well as the need for high energy infrastructure (Ho and Anda, 2004).

In response to Perth’s water supply concerns the Western Australian Government implemented a State Water Strategy in February 2003. Part of this strategy was to create a Premiers Water Foundation to support research and development projects that investigate water conservation and reuse. A project titled “Demonstration of Decentralised Wastewater Recycling in Urban Villages” was funded by the foundation and aims to achieve a number of demonstration projects and research studies. This technical report is the second of three reports within Premiers Water Foundation project and is focused on technical requirements associated with decentralised wastewater recycling.

The aim of the research study is to investigate the technical requirements and technologies (technical elements) associated with the successful implementation of an urban village wastewater recycling system within the PMR, for which a model can be formulated to create reliable management systems and improved protection of public health and the environment.
