Sludge management is an important aspect of effluent pond management but even more critical for a covered anaerobic pond (CAP). Inadequate sludge management can cause a CAP to fail – undermining a substantial capital investment and setting back the rate of adoption of such systems. This project conducted sludge surveys at Bears Lagoon Piggery. Bears Lagoon Piggery is a commercial grow-out operation accommodating, on average, 23 000 standard pig units (SPU). The surveys identified a range of sludge characteristics, including TS and VS concentrations, to help understand on-farm sludge removal and management.
