Client: FAST-FOOD RESTAURANT IN DECEPTION BAY, QUEENSLAND
A fast-food kitchen depends on reliable grease trap access for regular maintenance. In May 2026, Citi Industries completed a grease trap lid replacement at a Deception Bay restaurant. The job involved opening a concrete slab, installing metal access covers and making good the concrete around them.
At this restaurant, the trap sat in a tight service area, with little room around its access points. This was not a complete grease trap replacement. The restaurant needed work on the existing chamber and its surrounding surface.
Project Overview
An existing grease trap served the restaurant’s trade waste system. This project concentrated on the access lids above that chamber rather than a new tank or drainage network.
The crew opened the concrete slab around the existing trap. More than one metal access cover was fitted within the concrete. They made good the concrete around the covers, leaving a tidy surface.
The covers gave servicing contractors access to the trap. Around them, the crew made good the concrete within the tight service area.
Scope of Work
Opened the existing concrete slab around the grease trap access area.
Fitted multiple metal access covers at the existing trap.
Made good the concrete around the covers after installation.
Completed the replacement within the confined restaurant service area.
Challenges
Working in a Confined Service Area
The grease trap access points were surrounded by concrete within a compact service area. Space around the opening was limited.
That matters because the crew had to work around an existing installation. Contractors also need access to the same chamber during future grease trap servicing. The surrounding surface therefore mattered alongside the replacement covers.
Opening the Existing Slab
Work within the concrete surface was necessary around the access points. The crew opened the slab at the existing trap location. Once the lids were fitted, the disturbed area needed a finished surface.
Unlike a commercial grease trap installation, this job did not centre on placing a new tank. The challenge involved the access arrangement already built into the restaurant’s service area.
Finishing Concrete Around Several Lids
Multiple metal covers were present in the finished area. The concrete therefore met more than one metal edge, making the surrounding surface part of the job. Each cover needed a neat concrete finish around its edges.
Solutions
Opening the Work Area
At the existing grease trap, the crew opened the concrete around the access area.
Fitting the Metal Access Covers
Citi Industries fitted several metal access covers into the concrete around the grease trap. Those covers provide access for cleaning and inspection.
Each cover had to sit within the slab around the existing opening. The work was therefore linked to the surrounding concrete, not simply an exchange of loose lids.
Citi Industries’ grease trap lid repairs and replacement services cover access lids at commercial sites. The Deception Bay job combined metal cover replacement with concrete work around the chamber.
Making Good the Concrete
After fitting the covers, the crew made good the concrete around their edges. The metal covers sat within the repaired concrete surface.
That finishing work gave the restaurant a completed access area rather than an exposed slab opening.
Grease Trap Compliance and Trade Waste Servicing
A lid replacement does not remove a restaurant’s responsibility to maintain its grease trap. Grease trap compliance also depends on the applicable trade waste permit and servicing arrangements. The cover is only one part of that system.
Unitywater’s trade waste requirements explain that food businesses generally need approved pre-treatment and regular servicing. The required cleaning frequency appears in each business’s permit. Operators should keep the access area available to servicing contractors.
Queensland’s Plumbing and Drainage Regulation 2019 forms part of the rules governing regulated plumbing and drainage works. Check the applicable rules before arranging plumbing and drainage work.
In May 2026, the Deception Bay restaurant received multiple metal access covers set into made-good concrete. The open slab was finished, leaving a tidy surface within the limited service area.
With the surface repaired, the restaurant had finished access points for future grease trap cleaning and maintenance. This work addressed both the covers and surrounding concrete, rather than replacing the wastewater tank.
