Grease traps (https://en.wikipedia.org/wiki/Grease_trap) are critical components in commercial kitchens and food establishments. These devices intercept fats, oils, and grease (FOG) before they enter the wastewater system. Without proper grease management (https://drainblasters.co.za/grease-trap-cleaning-cape-town/), these substances can solidify in pipelines, leading to blockages, unpleasant odours, environmental pollution, and fines. South Africa has put forward a number of guidelines, municipal bylaws, and enforcement policies to ensure businesses remain compliant. Learn about grease trap regulations in South Africa such as cleaning schedules, compliance, legal risks, and best practices for food businesses.

Legal Requirements for Grease Trap Installation
In most major municipalities across South Africa, including Cape Town, Johannesburg, and Durban, the installation of a grease trap is a legal requirement for food-serving establishments. According to local government regulations, any facility that prepares food or handles large volumes of grease must install and maintain a grease trap.
Municipal bylaws generally mandate that:
- The grease trap must be of an appropriate size and design based on the kitchen’s capacity.
- It must be installed in a location that allows easy access for maintenance and cleaning.
- A certified plumber or approved contractor should carry out the installation.
Failure to install a grease trap or non-compliance with sizing requirements can result in penalties or the suspension of a business’s operating license.
How Often Should Grease Traps Be Cleaned?
While regulations vary slightly between municipalities, a general benchmark used across South Africa is the “25% rule.” This rule states that a grease trap must be cleaned when the combined amount of FOG and solids in the trap reaches 25% of the tank’s capacity.
Typically, businesses are required to:
- Clean their grease traps at least once every 30 days.
- Maintain cleaning records for inspection by environmental health officers or municipal agents.
- Use licensed waste disposal companies for the removal and treatment of grease trap waste.
Restaurants, fast-food outlets, and large catering operations may require more frequent servicing due to higher grease output.
The Environmental Risks of Non-Compliance
Improper grease trap maintenance is not just a plumbing issue—it becomes an environmental one. Blockages caused by FOG lead to sewer overflows, contaminating rivers and urban waterways. In severe cases, this pollution can result in legal action under the National Water Act and National Environmental Management Act.
Moreover, grease that escapes into the public sewage system contributes to fatbergs—large, solidified clumps of waste—that are expensive and difficult for municipalities to remove. Businesses that contribute to these issues may be liable for cleanup costs and face reputational damage.
Grease Trap Cleaning Protocols and SOPs
Standard Operating Procedures (SOPs) for cleaning a grease trap include:
- Removing the lid carefully and inspecting the trap.
- Measuring the amount of FOG and solids present.
- Skimming off the grease layer.
- Pumping or scooping out solids and wastewater.
- Scrubbing and inspecting internal baffles and walls.
- Recording the service and scheduling the next clean.
Some businesses attempt to manage this in-house, but professional grease trap cleaners like Drain Blasters are trained to carry out the full procedure in line with regulatory expectations. Using an accredited cleaning company also provides a documented paper trail for compliance inspections.
Record Keeping and Inspection
Businesses are expected to maintain a Grease Trap Maintenance Log that records:
- Date of each clean
- Name of the service provider
- Volume of grease and waste removed
- Method and destination of waste disposal
Municipal authorities may conduct routine or unannounced inspections. During these, they will assess the condition of the grease trap, the maintenance logs, and the facility’s waste disposal contracts. If found non-compliant, businesses are typically given a short period to rectify the issue or face fines.
South African Standards and Bylaws
Each metropolitan area in South Africa enforces its own specific set of bylaws that cover grease trap sizing, installation, and maintenance. However, most align with the general framework provided by the Department of Water and Sanitation and environmental health departments. Some important documents include:
- Government Gazette No. 41100 (GN982): This outlines minimum standards for the disposal of FOG and other industrial wastewater.
- South African Bureau of Standards (SANS): These set criteria for plumbing installations and waste treatment systems.
- Municipal Wastewater Discharge Bylaws: These often specify prohibited discharges, including untreated grease and oil, into the sewer system.
It is advisable for businesses to consult with local municipalities or wastewater authorities to ensure they follow the most current standards.
Selecting a Grease Trap Service Provider
Choosing a qualified service provider is not just about convenience—it’s a compliance issue. A reliable contractor should:
- Be registered to transport and dispose of grease trap waste.
- Provide manifests or certificates of disposal.
- Offer routine service contracts and emergency call-outs.
- Educate clients on record-keeping and inspections.
Drain Blasters, as a trusted liquid waste and drain cleaning specialist, ensures all cleaning is documented and disposed of in accordance with South African environmental regulations.
Industry Trends and Sustainability
Sustainability in grease trap maintenance is gaining traction. Progressive waste management companies are investing in technologies that convert FOG into biodiesel or use waste separation systems to reduce environmental impact. These practices not only enhance a company’s green credentials but also contribute to national waste reduction goals.
Businesses looking to improve their sustainability can ask their service providers if the grease waste is recycled, composted, or responsibly incinerated.
Final Thoughts on Grease Trap Regulations in South Africa
Remaining compliant with grease trap regulations in South Africa is not optional for food-based businesses. It protects public health, the environment, and your own infrastructure from costly damage. By investing in regular maintenance and working with licensed professionals, you ensure smoother operations and legal peace of mind.
