Hi William,
It sounds like you are referring to the wastewater plant. I found this recent article: Roadtrain® Delivers Safe Environmental Discharge for Saibai STP from Hydrolux, the supplier of the packaged plant. This article states, “The process has been specifically designed to suit remote installations and standardized across The Straits in six locations.” Researching through their website will likely answer all your questions related to the technical specifications.
An excellent start to learning more about local regulations is to check our section on Introduction to Local Government in the Torres Strait.
I hope this helps.
Regards,
Jean
