Continuing moves towards full cost recovery for potable water and the impending privatization of water supplies in the Melbourne area have enhanced public interest in the reuse of wastewater, and particularly the domestic use of greywater. Victoria University of Technology, together with support from Melbourne Water and the Department of Health and Community Services, has been investigating the practicalities, costs and social attitudes of using greywater in and around the home. Four ＇＇typical＇＇ Melbourne homes were selected and plumbed to utilize greywater for toilet flushing and garden irrigation. Social surveys were conducted by mail and phone to homeowners to determine perceived attitudes towards greywater reuse, Greywater from baths, showers, laundry troughs and washing machines is being examined for physical, chemical and microbiological parameters to determine the potential health and environmental risks associated with reuse. Soil tests were also undertaken on gardens to determine any long-term detrimental effects that might occur as a result of using greywater. This paper describes the greywater testing, results of filtration and filter designs, appropriate disinfectants, and physical findings to date. The two-year project is due for completion early in 1995.
