Biosolids are the major, unavoidable by-product of the sewage treatment process. Biosolids are largely used as soil conditioner in the agriculture sector due to a high nutrient value to improve soil structure and water retention capabilities.
The updated strategy will provide a plan guiding biosolids management and infrastructure investment in the region.
This study will further develop reuse options considered to date, develop an understanding of the impacts of new non-cost drivers, improve the robustness of adopted assumptions, and explore alternative approaches and uses into the future.
Council and WBW are continually striving to avoid, reduce and manage environmental risks in the Fraser Coast Region.
Currently WBW manage their biosolids based on a management program completed in 2011, which predates recent legislation under the end of waste code.
Initial baseline assessments and legislation reviews have already been undertaken during the preliminary stages of this project.
The Australian Water Association highlights that biosolids may be used due to their high nutrient value to improve soil structure and water retention capabilities. The Fraser Coast region uses biosolids in the agriculture sector for:
