Australia’s CSIRO has a major research project on urban water systems called the Urban Water Program (UWP), which involves collaboration between its divisions of Molecular Science, Building Construction and Engineering, and Land and Water. It is the aim of this project to identify opportunities for more sustainable urban water systems. The project involves characterisation of water systems by costs, water use and demand, contaminant flows, treatment technologies, public acceptance and the costing of urban water system impacts on environments external to the ...

The aim of this study was to evaluate the potential of different separation techniques for local recovery of faecal nutrients. Separation by Aquatron, filtration, flotation and sedimentation was tested in the laboratory. Only the separation of faecal matter from flushwater was investigated. For efficient nutrient capture, the system has to be combined with urine-diverting toilets.

The aim of this study was to evaluate the potential of different separation techniques for local recovery of faecal nutrients. Separation by Aquatron, filtration, flotation and sedimentation was tested in the laboratory. Only the separation of faecal matter from flushwater was investigated. For efficient nutrient capture, the system has to be combined with urine-diverting toilets.
In this study we found that the extraction of nutrients from the faeces to the liquid occurred rapidly. Therefore, to effectively separate the faecal nutrients and particles from ... Read More

Source control measures include rainwater tanks, infiltration trenches, grassed swales, detention basins and constructed wetlands that can be used in housing allotments and subdivisions. A methodology for evaluating the regional economic benefits due to implementation of source control measures is presented and illustrated for two case studies in the Lower Hunter and Central Coast regions [...]
Source control measures include rainwater tanks, infiltration trenches, grassed swales, detention basins and constructed wetlands that can be used in housing allotments and subdivisions. A methodology for evaluating the regional economic benefits due to implementation of source control measures is presented and illustrated for two case studies in the Lower Hunter and Central Coast regions of New South Wales, Australia. It is demonstrated that use of rainwater tanks to supplement mains water supply for toilet, hot water and outdoor uses can very ... Read More
