In the food service business, owners have to find a balance between taste, service, and following local and national rules. These important operations depend heavily on reliable infrastructure. Due to stricter rules and regulations in Queensland, business owners are now making responsible waste management a top priority. Cafés produce a lot of wastewater with food scraps and grease, which, if not disposed of properly, might clog pipes, cause work stoppage, and result in big environmental problems. This is where professional services like commercial grease trap installation and café trade waste plumbing are very important. Citi Industries, a Queensland‑based trade waste and commercial plumbing specialist with over 20 years’ experience, was engaged to deliver a full plumbing and trade waste upgrade for a busy café location. With expertise in grease trap design, hydraulic planning, and below-ground grease trap systems QLD, Citi Industries ensures hospitality businesses stay compliant, efficient, and environmentally responsible. This case study explores the real challenges crews faced on site, the tailored hospitality plumbing fit-out services provided, and how the project exceeded expectations and all while meeting strict trade waste venting compliance standards.
Challenges
Cafes generate distinctive waste streams that require specialised management
- Grease and oil from food preparation
- Organic matter like food scraps
- Cleaning agents mixed with or dissolved the water.
Without reliable commercial grease trap installation, waste can enter public sewer lines, causing costly blockages and regulatory violations. The café in this project reported:
- Persistent blockages and drain slowdowns
- Fines and warnings from the city council for non-compliant wastewater discharge
- External grease trap access points that were unsafe for customers and pedestrians
- Inadequate fixture waste and water connections
- A build‑up of waste and poor separation of FOG (fats, oils, and grease)
Foot traffic outside the café made traditional top‑entry grease trap lids unsafe, requiring upgrades to pedestrian‑safe grease trap lids to protect customers while maintaining access for maintenance. The combination of ageing infrastructure and increased customer turnover meant that a robust solution was needed, fast.
Solutions
To address these issues comprehensively, Citi Industries deployed a specialist project team experienced in café trade waste plumbing solutions, including custom design, excavation, and installation:
1. Below-Ground Grease Trap Installation
Citi Industries designed and installed a purpose-built below-ground grease trap system in QLD capable of handling the high grease volumes generated by the café’s daily operations. Placing the system below ground maximised kitchen space, reduced overt clutter, and ensured ease of service access without interrupting kitchen workflows.
- Customised to café wastewater demands
- Sized to council and EPA standards
- Designed to facilitate routine cleaning and monitoring This upgrade resolved recurring blockages and brought the business into compliance quickly.

- Pedestrian‑Safe Grease Trap Lids
Standard grease trap lids are not designed for high‑traffic pedestrian zones. Citi Industries replaced existing access points with pedestrian‑safe grease trap lids, which:
- Reduce slip and trip risk for customers.
- Withstand foot and trolley traffic.
- Fully support safety and council compliance.
Fitting these specialised lids ensured both safety and durability in the café’s busy outdoor seating area.
3. Hand Excavation Plumbing Works
The crew undertook precise hand excavation plumbing works required to install the underground system without disrupting existing services or landscaping. Hand excavation allowed
- Careful soil and infrastructure removal around utilities
- Minimised risk to surrounding paving and outdoor fixtures
- A clean finish with minimal restoration required
This method ensured easy installation without disrupting café operations.
4. Fixture Waste and Water Connections
Citi Industries reviewed all fixture waste and water connections, integrating them into the new grease trap system so that:
- Drainage was consistent and compliant.
- Wastewater from sinks, dishwashers, and prep areas flowed efficiently to the trap.
- Water supplies were maintained with no loss of pressure or system stress.
This holistic approach ensured the entire kitchen plumbing system worked as a single, efficient unit.
5. Backflow Prevention RPZD Valve
To eliminate the risk of contaminated water reversing into clean supply lines, a Backflow Prevention RPZD valve was installed. This device:
- Safeguarded potable water supplies
- Provided added public health protection
- Met key plumbing and health standards for commercial kitchens
High-risk environments, such as cafés, require these systems to prevent cross‑connection hazards.
Final Outcome
Thanks to the specialist team at Citi Industries, the café’s infrastructure received a complete transformation:
- Reliable grease management that prevents costly blockages
- Full compliance with regulatory and safety standards
- Improved operational efficiency for kitchen staff
- Safer premises for customers and passers‑by
- Enhanced wastewater control that protects local sewer systems
This project outcome reflects Citi Industries’ track record in delivering dependable trade waste and plumbing solutions across Queensland. In the past case studies from grease trap repairs for shopping centres to complex trade waste system upgrades underscores their capability across both commercial and industrial contexts.
