Commercial laundry plumbing in Burleigh Heads came with an immediate obstacle. Setting up a commercial laundry is already a big undertaking. When the existing plumbing runs right through where your key equipment needs to go, it stops the whole job before it starts. That is exactly the situation this Burleigh Heads operator faced.
The job needed a 2,000-litre underground lint trap. The problem was that an existing stormwater line ran directly through the planned position. The crew also needed to reach washer and dryer connection points without losing access to the underground services.
Project Overview
The commercial laundry plumbing scope covered underground drainage, water pipework and a gas supply arrangement for future dryer connections. Laundry wastewater carries lint and fibres, so the proposed system included a dedicated interception tank. The team also had to connect the fixtures shown on the tenancy plan.
Scope at a glance:
- Install a 2,000-litre underground lint trap and the new trade waste line.
- Relocate the stormwater line crossing the planned tank position.
- Connect fixtures and vent the tank and trade waste pipework to atmosphere.
- Fit five swivel expansion joints requested by council.
- Provide hot and cold water pipework for washers and dryers.
- Install gas pipework, a regulator, isolation valves and an emergency stop.
- Protect the external gas bottle position with four bollards.
Challenges
Making Room for a Below-Ground Lint Trap
The proposed lint trap sat where an existing stormwater line already ran. Before installing it, the crew needed to scan and cut concrete, excavate and relocate that line.
Connecting Several Services in One Tenancy
Washers needed one water pipe size and dryers another. The layout also required trade waste drainage, atmospheric vents and a separate gas supply. Council requested five swivel expansion joints along the new waste line.
The external gas bottle position required a regulator, with isolation valves behind the planned dryers. An emergency stop with signage was also needed inside the tenancy. Four bollards were specified to protect the bottles and nearby pipework.
Solutions
Stormwater Relocation and Excavation
The crew scanned and cut concrete, then excavated for the lint trap and drainage. They moved the stormwater line away from the planned tank position and removed the spoil.
Installing the 2,000-Litre Lint Trap
Citi Industries installed the underground lint trap where the amended drainage layout allowed it to fit. The tank intercepts lint and fibres carried by laundry wastewater before that flow reaches downstream drainage. Its Class D access lids support heavy-duty access and future servicing.
Citi Industries’ trade wastewater solutions included connecting the laundry fixtures to the lint trap through a new waste line.
Trade Waste Drainage and Venting
The crew ran a new trade waste line through the tenancy and connected the fixtures shown on plan. They also ran vents to atmosphere for the tank and new line.
For the Gold Coast trade waste approval process, Citi Industries fitted five swivel expansion joints requested by council.
Citi Industries’ commercial plumbing services covered the new drainage, vents and fixture connections. The crew installed them to AS/NZS 3500 plumbing and drainage requirements.
Hot and Cold Water Services
For the washers, the crew installed 25mm hot and cold water lines. Dryers received 20mm hot and cold lines. New hot water pipework connected to the existing unit.
Gas Pipework and Safety Controls
From the external gas bottle position, the crew ran new pipework and fitted a regulator. Isolation valves went behind the planned dryers, with an emergency stop and signage inside the tenancy.
The crew installed the gas controls under Queensland gas work licensing rules. Four bollards protected the external bottle location and pipework. Other contractors remained responsible for final dryer connection and commissioning.
Concrete Reinstatement and Site Clean-Up
After the underground work, Citi Industries reinstated the affected concrete and removed the remaining plumbing spoil.
Final Outcome
Relocating the stormwater line cleared space for the 2,000-litre lint trap. The tenancy gained the specified trade waste drainage, water and gas connections for its planned equipment. The project was completed in January 2026.
Common Questions About Commercial Laundry Plumbing
Why include a lint trap in a laundry drainage system?
Commercial washing can release lint and fibres into wastewater. A lint trap gives that material an interception point before downstream drainage. The required arrangement depends on the site’s fixtures and trade waste conditions.
Can a commercial laundry fit-out use an existing hot water unit?
It depends on the unit and the equipment requirements. At this site, Citi Industries connected the new hot water services to the existing unit.
What should be checked before a similar fit-out?
Start with the planned machine locations, available water supply and existing underground services. Then check the trade waste requirements and access for tank maintenance. An early review can identify clashes with existing services before work begins.
