Lint Trap Installation in Port of Brisbane, QLD

 

Project Overview

Citi Industries was engaged to design and deliver a fully compliant Trade Waste Installation QLD solution for a new commercial laundry facility located at Port of Brisbane. The site operates within one of Queensland’s most regulated industrial precincts, where strict environmental, hydraulic, and safety standards apply.

As an experienced Commercial Plumber Brisbane, Citi Industries was tasked with providing a system capable of managing high volumes of lint and solid waste produced by industrial washing equipment. The installation needed to meet local authority requirements while ensuring durability, ease of maintenance, and future scalability.

The project was required to align with Urban Utilities requirements for Trade Waste Compliance, ensuring wastewater discharge met regulatory standards from day one.

Key objectives for the project included:

• Installation of a robust below-ground lint trap system
• Protection of downstream sewer infrastructure
• Compliance with Queensland trade waste and hydraulic regulations
• Infrastructure designed to support future operational growth
• Minimal disruption within a high-traffic port environment

This project further reinforced Citi Industries’ position as a trusted provider of commercial plumbing and trade waste solutions in high-risk, high-compliance environments.

 

Challenges

Industrial laundries present complex challenges for trade waste management, particularly when located within an active port facility where safety, access, and operational continuity are critical.

The primary challenges identified included:

• High volumes of lint and solid waste capable of causing sewer blockages
• Strict port authority safety controls and limited work windows
• Constant heavy vehicle movement across installation zones
• Existing underground services requiring precise identification prior to excavation
• The need to future-proof infrastructure without disrupting current operations

If not addressed correctly, these challenges could result in:

• Sewer overflows and environmental incidents
• Breaches of trade waste regulations
• Costly downtime and remediation
• Long-term maintenance issues

To mitigate these risks, the client required a proven Trade Waste Specialist with demonstrated experience in port, industrial, and high-compliance environments.

 

Solutions Provided by Citi Industries

Citi Industries delivered a fully engineered, end-to-end solution, managing the project from planning through to commissioning and reinstatement. A single-contractor approach ensured efficiency, accountability, and compliance at every stage.

The scope of works included:

• Concrete scanning using ground-penetrating radar to identify existing underground services
• Controlled concrete cutting and excavation to prevent damage to surrounding infrastructure
• Supply and installation of a Below Ground Lint Trap 2000L system designed for industrial use
• Strategic placement of the lint trap within the adjacent car park to allow easy access for servicing

The selected 2000L Below Ground Trap was chosen due to its:

• High capacity to manage industrial lint discharge
• Structural integrity suitable for port environments
• Compatibility with traffic-rated lids for heavy vehicle loads

To support both current operations and future expansion, Citi Industries engineered:

• Trade waste drainage allowing connection of up to three commercial washing machines
• Scalable infrastructure that eliminates the need for additional excavation as demand increases
• Durable surface finishes designed to withstand ongoing industrial traffic

The project also required comprehensive Trade Waste Drainage Systems to ensure reliable wastewater discharge. Citi Industries completed:

• New sewer connections integrated into the existing external sewer line
• Hydraulic configurations designed to minimise surcharge and overflow risk
• Installation of a 100mm vent to atmosphere to manage pressure and odour
• Placement of three clear-outs to simplify maintenance and emergency access

As part of the compliance scope, Citi Industries completed a certified RPZD Valve Installation, supplying and installing a Reduced Pressure Zone Device to prevent backflow contamination of the potable water supply. This measure ensured the system passed inspection and remained compliant through routine testing and certification.

All works were delivered in line with Queensland regulations governing Grease Trap & Lint Trap Installation, ensuring the system met both authority and operational requirements.

 

Final Outcome

The completed project delivered a durable, compliant, and future-ready trade waste system tailored to the demands of a port-based commercial laundry.

Key outcomes achieved included:

• Full compliance with Trade Waste Installation QLD standards
• Effective interception of lint and solids before entering the sewer network
• Reduced risk of blockages, overflows, and environmental breaches
• Infrastructure engineered for long-term durability and scalability
• Minimal disruption to port operations during installation

Following commissioning and pressure testing, Citi Industries completed full site reinstatement works. These included:

• Re-concreting with 32MPA concrete
• Single-mesh reinforcement for structural strength
• A broom finish suitable for high-traffic industrial areas

This ensured the car park surface was restored to its original condition while maintaining the strength required for ongoing heavy vehicle use. The attention to reinstatement and finishing highlights the difference between specialist commercial contractors and general plumbing providers.

The project demonstrates the importance of engaging an experienced Commercial Plumber Brisbane capable of delivering compliant, engineered solutions in complex environments.
