Project Overview
A family-owned seafood retailer in Bellbird Park, QLD required a durable and regulations-compliant trade waste system that can handle their day-to-day operations. Citi Industries, as expected, delivered an engineered grease trap installation in Brisbane that met all of the client’s specifications and complied with Queensland regulatory and environmental standards.
Citi Industries took charge of the project from the start: from planning and excavation, through to the final details, testing, and compliance checks. Such depth of management is only proof of the company’s experience as a commercial plumber in Bellbird Park. As part of a larger trade waste plumbing in QLD solution, it was important to ensure the client complied seamlessly with urban utilities and local council requirements to avoid delays in their day-to-day operations.
The seafood processing industry has a gauntlet of challenges, which includes dealing with grease, fats, oils, and solids. Inability to handle these problems may lead to drainage system failures. Citi Industries engineered a system that highlights durability, accessibility, and performance longevity, while at the same time minimising the need for frequent repair.
Key project objectives included:
- A 1000 Litre Grease Trap Installation suitable for a high-demand seafood retail environment
- Full compliance with local trade waste approvals and drainage standards
- Integration of the below-ground infrastructure designed to withstand vehicular traffic
- Safe execution within an active commercial precinct with public access
The project highlighted Citi Industries’ talent as a licensed tradewaste plumber in Bellbird Park, and their ability to deliver reliable systems capable of handling daily high-risk food-service operations and comply with strict requirements.
Challenges
The installation had to address a bevvy of technical, engineering, and regulatory-related challenges. Citi Industries, through years of experience, employed careful strategising and execution to pull off the desired results.
Site and Operational Constraints
- The grease trap location required a below-ground Class D grease trap capable of withstanding vehicular loads.
- Excavation and concrete cutting were completed in an active commercial environment with ongoing pedestrian access.
- Existing underground services were identified using concrete scanning to prevent damage and service interruptions.
- The work area required strict safety controls, including barricading and traffic management.
Compliance and Trade Waste Requirements
- The seafood retailer required strict adherence to Trade Waste Plumbing QLD regulations.
- The approval process involved securing the required Trade Waste Permits

Internal Plumbing Integration
- Multiple kitchen fixtures required connection to the new trade waste line, including:
- Wash sinks and prep sinks.
- Dishwasher connections
- Basin and tapware supplied by the client
- Backflow protection to avoid cross-contamination and keep potable water systems safe.
