Improved Piggery Effluent Management Systems Incorporating Highly Loaded Primary Ponds

This project has demonstrated the technical feasibility and benefits to the Australian pig industry of utilising highly loaded (and significantly smaller) primary effluent ponds for the treatment of effluent from piggery sheds. In comparison to conventional effluent ponds, the project results indicate that highly loaded ponds offer comparable levels of treatment (solids reduction) along with a range of practical and financial benefits including easier desludging, lower overall odour emissions, reduced construction costs, reduced lining and covering costs, and improved potential to establish or expand piggeries at sites limited by separation distance to sensitive receptors
