Triple Interceptor Trap Cleaning Melbourne Triple interceptor traps are one of the most widely installed grease management systems in Melbourne’s commercial kitchens. Their proven three-chamber design provides effective, reliable FOG separation — making them the standard choice for restaurants, pubs, clubs, and institutional kitchens. Melbourne Grease Trap Cleaning passes triple interceptor cleaning enquiries from across the metropolitan area to local contractors.

How Triple Interceptor Traps Work The triple interceptor design uses three connected chambers to progressively separate fats, oils, and grease from kitchen wastewater:

Chamber 1 (Primary): Receives wastewater directly from kitchen fixtures. Heavy solids settle to the bottom while FOG floats to the surface. This chamber captures the bulk of solid waste and the heaviest grease. Chamber 2 (Secondary): Partially treated water flows through a baffle into the second chamber, where further FOG separation occurs at a reduced flow rate. Finer grease particles rise to the surface. Chamber 3 (Tertiary): The final polishing chamber captures any remaining FOG before treated wastewater exits to the sewer system. This chamber typically accumulates the least grease but is essential for meeting discharge quality standards. Key Specifications Capacity: 1,000 to 4,000 litres total across all three chambers Materials: Concrete or plastic construction with internal baffles separating each chamber Best suited for: Standard commercial kitchen installations including restaurants, hotels, pubs, aged care, and schools Cleaning frequency: Monthly to quarterly depending on kitchen output Australian Standard: AS 4494 Why All Three Chambers Matter A common mistake with triple interceptor maintenance is only cleaning the first chamber — which is where the most visible grease accumulates. However, FOG builds up in all three chambers over time. If the second and third chambers are neglected, they lose their separation capacity, and untreated grease passes through to the sewer. This violates your Trade Waste Agreement and can trigger fines from your water authority. A thorough clean addresses all 3 chambers on every visit.

The Cleaning Process Open all access points to each of the three chambers Measure FOG levels in each chamber for compliance records Pump out all three chambers sequentially using vacuum tanker High-pressure water jet all chamber walls, baffles, and connecting pipes Inspect baffles, tee pieces, and structural integrity of each chamber Verify clear flow through all three chambers Issue Waste Transport Certificate and detailed service report Compliance & EPA Licensing All waste removed from triple interceptor traps is transported under EPA Victoria licence and disposed of at approved receival facilities. Your Waste Transport Certificate documents the waste type, volume, and disposal location — essential records for Trade Waste Agreement compliance with City West Water, South East Water, or Yarra Valley Water.
