Suppose you are a restaurant, café or commercial kitchen operating in your area. In that case, you must comply with your local regulations, for example, the use of grease traps to ensure the usage and disposal of grease is regulated to control overflow and environmental damage.
But you cannot just install a unit under the sink.
It is essential to treat wastewater and prevent drain blockages caused by FOG (Fats, Oils & Grease). In addition to this, you should be respectful towards the environment.
When it comes to installing a grease trap, please read our latest blog “What to Expect During a Grease Trap Installation” for the complete guide. This article also helps to make sure the unit you receive is legal under all regulations in your area.
1. Site Assessment and Compliance Checks
Before installation begins, a licensed technician will perform a site inspection. This ensures your grease trap:
- Meets local council regulations and water authority standards
- It is correctly sized for your kitchen’s waste output
- Fits seamlessly into your current plumbing system
During this stage, your installer will also assess wastewater flow rates and recommend the ideal grease trap capacity to prevent overflow and blockages.
2. Choosing Your Grease Trap For Your Business
To operate properly and comply, a grease trap system that suits one’s purpose has to be chosen. Factors to consider include:
- Capacity and size are determined by the number of sinks, frequency of dishwasher operation, and peak service hours.
- Material type – is it stainless steel, fibreglass, or durable plastic
- Placement – underground grease trap installation or above-ground systems
Choosing the perfect one guarantees that it will last a lifetime. It is effortless to clean while being efficient, saving you money in the long run.

3. Preparation Before Installation
After your grease trap has been designed and approved, work can begin. This may involve:
- Applying for necessary permits and approvals
- Clearing the area and creating access for the installation of the workbench
- Temporarily adjusting kitchen operations to avoid downtime
A professional grease trap installation service will coordinate with plumbers, electricians, or contractors if needed.
4. The Grease Trap Installation Process
The day of your installation, your installer will:
- Prepare the installation site or excavation area.
- Locate the grease trap in an ideal connection spot.
- Furnish inlet and outlet pipes with devices for separating solids and grease from the wastewater.
- Seal the unit to prevent leaks and odour issues. This can be wrapped up with a seal that will keep any liquid from leaking out, eliminating the smell.
- Check the water flow and compliance of the system.
Most commercial grease trap installations take between a few hours and a full day (4-8 hours/day), depending on size and complexity.

5. Post-Installation Inspection and Compliance
After the grease trap is installed, your provider will:
- Conduct final compliance checks
- Provide operation and maintenance instructions
- Schedule your first grease trap cleaning or pump-out
- Supply documentation for council or water authority records
6. Long-Term Maintenance and Cleaning
For the record, if you want your grease trap to stay useful, you must:
- Follow the recommended cleaning schedule (usually 1–3 months apart)
- Do not pour large amounts of oil or food waste down any sink.
- Keep your maintenance records for inspection purposes.
By signing a maintenance contract with your installer, they will ensure to arrive on time to clean the equipment and avoid expensive repairs.
