EPA Victoria provides regulatory guidance for waste and pollution management. Grease traps require frequent cleaning, often monthly, because grease solidifies quickly and causes blockages if neglected.
Sewer systems are designed to handle human waste, soaps, and other household byproducts. This ensures they don’t pollute local waterways. In areas without mains sewer (rural/edge suburbs), some properties still use septic tanks. Septic tank pump outs are required to maintain these onsite systems in compliance with EPA rules.
Grease traps and septic tanks serve different roles in wastewater management.
For Melbourne property owners, understanding the difference ensures the right system receives the correct maintenance.
