Greywater Reuse

Domestic wastewater reuse is currently not permitted anywhere in Australia but is widely supported by the community, promoted by researchers, and improvised by up to 20% of householders. Its widespread implementation will make an enormous contribution to the sustainability of water resources. Integrated with other strategies in the outdoor living environment of settlements in arid lands, great benefit will be derived. This paper describes six options for wastewater reuse under research by the Remote Area Developments Group (RADG) at Murdoch University and case studies are given where productive use is being made for revegetation and food production strategies at household and community scales. Pollution control techniques, public health precautions and maintenance requirements are described. The special case of remote Aboriginal communities is explained where prototype systems have been installed by RADG to generate windbreaks and orchards. New Australian design standards and draft guidelines for domestic greywater reuse produced by the Western Australian State government agencies for mainstream communities are evaluated. It is recommended that dry composting toilets be coupled with domestic greywater reuse and the various types available in Australia are described. For situations where only the flushing toilet will suffice the unique “wet composting” system can be used and this also is described. A vision for household and community-scale on-site application is presented.

Three new species of jumping plant-lice (Psylloidea) are described from Western Australia. Acizzia hughesae sp.n. occurs on Acacia veronica Maslin (Fabaceae: Mimosoideae), A. mccarthyi sp.n. on an undescribed species of Grevillea (Proteaceae) identified by the Western Australian State Government as in need of conservation action (Grevillea sp. ‘Stirling Range’) and Trioza barrettae sp.n. from the critically endangered Banksia brownii (Proteaceae). These new species of jumping plant-lice are considered rare, and at risk of extinction, or coextinction, as they are recorded from plant species with highly restricted distributions in the south-west of Western Australia. Indeed, the Western Australian State Government recently classified two of the three new jumping plant-lice species as threatened.

Reed Bed

This paper summarises the results of studies on four subsurface flow wetlands (reed beds) located in the moist sub-tropical north eastern corner of the Australian state of New South Wales. The reed beds, which are subjected to a variety of effluent types, all have a gravel substrate planted with Phragmites australis. All four units were found to maintain satisfactory treatment performance year round. Mean removal efficiencies ranged from 56% to 90% (SS), 70% to 93% (BOD), 38% to 66% (TN), 87% to 99.8% (Faecal coliforms), and 42% to 70% (TP - with one seasonal result of 0% for the eight year old unit) for the four reed beds. After eight years in operation the oldest reed bed was showing signs of phosphorus saturation with outlet TP concentrations exceeding inlet concentrations on some occasions. The youngest reed bed studied appeared to be operating efficiently after five months. A summer water balance on one of the reed beds revealed an average crop factor of 1.6 and a moisture loss to atmosphere of 40% of influent flow. Treatment performance (particularly for TN and SS) was found to be negatively correlated with rainfall during one study. The paper discusses the implications of the above results for on-site system designers and regulators and identifies areas for further investigation.

In many jurisdictions around the world, community safety and crime prevention activity is supported by interagency committees. In the Australian state of New South Wales (NSW), local government Community Safety Officers (CSOs) lead, support or participate in a range of interagency and ‘whole of government’ networks, most of which were established to support central NSW state government crime prevention and community safety initiatives. Research was conducted with the aim of exploring the CSOs’ experience of the ‘whole of government’ partnerships established to support community safety and crime prevention in NSW.[i] The findings support international research which suggests that central-local partnerships are inhibited by different agendas, responsibilities and power dynamics across different levels of government. Some of the key contextual challenges for this work include concerns about costs shifting from State to local government and about shifting State government priorities; barriers to funding and to accessing crime (and other) data; and various administrative burdens. Consequently, we argued that there is a need for formal engagement and negotiation between, on the one hand, State government agencies that steer NSW crime prevention and, on the other, community safety policy initiatives and local government. Such engagement could help overcome the perception, indeed the reality, that shifting and dumping costs and responsibilities to local government is creating a range of burdens for CSOs. [i] The authors thank the NSW Local Government Community Safety and Crime Prevention Network and the individual local government CSOs who kindly assisted and contributed to this research.

Domestic Effluent

In the past sewage ponding in indigenous settlements was commonplace as a result of overcrowding combined with inappropriate septic tank and leach drain design, installation and operation. The response over the past 10 years has been to develop reticulated sewerage systems to lagoons when the funds become available. These are often successful in terms of operation, improved public health and low maintenance but are expensive and wasteful of limited water supplies. Evapotranspiration (ET) is an effective method for on-site domestic effluent disposal in areas of Western Australia with soils of low permeability. Evapotranspiration systems have been established in a number of communities both for research/demonstration and as specified by architects. The systems usually follow two septic tanks for the disposal of all domestic effluent. A case study will be presented for a remote indigenous community where the ET systems installed for greywater only have been monitored over the last two years since installation. The use of evapotranspiration has enabled reuse of effluent for successful examples of revegetation and food production and points to the need for a holistic approach to design and service delivery in these communities that includes a total environmental management plan.
