Grease Trap Cleaning & Maintenance Services In Gauteng
What is grease trap cleaning?
Grease trap cleaning is the process of removing the accumulated fats, oils, grease (FOGs), and solid waste from a grease trap. Grease traps, also known as grease interceptors, are plumbing devices installed in commercial kitchens, restaurants, food processing facilities, and other businesses that generate greasy wastewater. Grease traps capture and separate FOGs from wastewater before it enters the main sewer system, preventing clogs, blockages, and environmental contamination.
How do grease traps work?
Grease traps operate by slowing down wastewater flow, allowing heavier particles to settle at the bottom while lighter fats, oils, and grease rise to the surface. This design helps prevent clogs and blockages, ensuring only relatively clear water exits into the main sewer system, reducing environmental impact.
Basic Working Principle:
Grease traps rely on the natural density difference between FOGs and water. As wastewater enters the trap, lighter FOGs rises to the top while denser food particles settle at the bottom, allowing cleaner water to exit the system.
Key Components of a Grease Trap:
- Inlet Pipe: Directs wastewater from the kitchen sink or drain into the trap.
- Flow Control Device: Regulates the speed of wastewater entering the trap to ensure proper separation.
- Primary Chamber: The first section where the FOGs starts to rise, and solids begin to settle.
- Baffles: Internal walls that slow down the flow, allowing for better FOGs separation.
- Outlet Pipe: Allows cleaned water to exit the trap while containing the FOGs and solids.
- Access Ports: For inspection, cleaning, and maintenance.
- Air Relief Valves: Prevent pressure build-up and allow proper ventilation.
Types of Grease Traps:
- Passive Grease Traps: Small, under-sink traps found in small kitchens.
- Automatic Grease Removal Units (AGRU): More advanced systems that automatically separate and remove FOGs.
- Gravity Grease Interceptors (GGI): Commercial kitchens and food processing plants often use larger, outdoor units.
Who typically needs grease traps?
Businesses and facilities that produce significant amounts of fats, oils, grease (FOGs), and food waste in their wastewater typically use grease traps. Regulations require these businesses to install grease traps to prevent FOGs from entering municipal sewer systems, which can cause blockages, environmental contamination, and costly plumbing repairs.
Typical Users of Grease Traps:
- Restaurants and Cafés: High-volume cooking, frying, and dishwashing produce a lot of grease-laden wastewater.
- Fast Food Outlets: High-turnover, fried food-focused businesses generate substantial FOGs.
- Commercial Kitchens: Found in hotels, resorts, hospitals, and large corporate cafeterias.
- Food Processing Plants: Facilities involved in meat processing, dairy production, or oil refining.
- Bakeries and Delis: Use fats and oils in cooking, baking, and food preparation.
- Butcheries and Meat Processing Units: Generate fats from meat cutting and processing.
- Catering Companies: Often handle large volumes of grease-rich foods.
- Supermarkets and Grocery Stores: With in-house delis, rotisserie sections, or prepared food counters.
- School and University Canteens: Serve large numbers of students and staff daily.
- Hospitals and Healthcare Facilities: Often have on-site kitchens to serve patients and staff.
- Food Trucks and Mobile Kitchens: Generate high levels of FOGs despite smaller operations.
- Hotels and Resorts: Large-scale meal preparation for guests and events.
- Pet Food Manufacturers: Often produce greasy and fatty products.

Why Grease Trap Cleaning is Important:
- Prevents Blockages: Regular cleaning prevents FOGs buildup, reducing the risk of clogged pipes and costly plumbing repairs.
- Complies with Regulations: Many local and national regulations require businesses to maintain clean grease traps to avoid fines and environmental violations.
- Odour Control: Cleaning eliminates the foul odours that can develop from decomposing grease and food waste.
- Improves System Efficiency: A clean grease trap functions more effectively, reducing the risk of backups and costly downtime.
- Protects the Environment: Prevents grease from entering the municipal sewer system, reducing the risk of water pollution and damage to aquatic ecosystems.
The Grease Trap Cleaning Process:
- Inspection: Assessing the trap’s condition and measuring the FOGs and solids levels.
- Pumping and Cleaning: Removing all trapped grease, fats, oils, and solids.
- Scraping and Power Washing: Thoroughly cleaning the trap’s walls, baffles, and components.
- Waste Disposal: Proper disposal of the collected waste in compliance with environmental regulations.
- System Testing: Checking for blockages, leaks, and overall functionality.
