Review of greywater reuse practices in Victoria

Greywater reuse has become popular in rural and urban communities of Australia. In recent years, the Barwon region of Victoria has been affected by drought and as a result, water restrictions were imposed at different stages. While a water conservation by-law was introduced in February 2003 with overwhelming community support, greywater reuse is still debated among householders, Environment Protection Authority (EPA), local councils, and the water authorities. Higher levels of greywater reuse are needed due to low average rainfall in the region and high water consumption per capita. This paper looks at the position of the different parties that govern greywater reuse and presents the factors that restrain uniform reuse practices. Factors considered include quantity and quality of greywater generated in the Barwon region, current regulatory controls as reviewed through a series of surveys of local councils and water authorities. While the water restrictions resulted in an increased demand for alternative means of watering garden areas, the regulatory conditions were found to be unsettled about greywater reuse, with a wide range of concerns making these authorities unwilling to encourage it.<br />
