Biosolids are the stabilised organic solids derived from the treatment of municipal sewage, and can be beneficially reused with appropriate control measures. They are widely used in broad acre agriculture throughout Australia.
The Department of Health (DOH) and the Department of Environment and Conservation (DEC) assess proposals to use biosolids. The use of biosolids will need to meet the requirements of the Western Australian Guidelines for Direct Land Application of Biosolids and Biosolids Products (PDF 158KB) to ensure that potential impacts on human health and the environment are addressed.
The Guidelines do not apply to sludges from animal industries or untreated septic tank sludges.
Biosolids applications of less than 1000 tonne do not require DEC approval but DoH approval is still required.
