Eight people complained to the Environment Protection Authority (EPA) about the foul odour during the orange processing season in August.
The EPA's regional manager, Jeff Cummins, says one of the ponds was very shallow and contained waste water with a high organic content.
"Offensive odour from these sorts of activities can be quite distressing on the local communities and it was really the inability of SPC to manage their treatment system that necessitated the EPA to intervene," he said.
