Grease traps for food businesses
A grease trap catches fats, oils and grease from a commercial kitchen before the wastewater reaches the sewer. Most commercial trade wastewater customers in Sydney Water’s area have to install and maintain one, or other pre-treatment equipment.
We install new grease traps and arrestors, connect the kitchen to them, and replace old ones during a fit-out. The price is fixed before we start.
Before you book
- Sydney Water approval. Most food businesses need formal approval to discharge trade wastewater, applied for through Sydney Water Tap in. The property owner or managing agent has to approve the application.
- Low-risk processes. Some low-risk activities are deemed processes and don’t need formal approval, but they still have to meet Sydney Water’s requirements.
- The right equipment. Only pre-treatment equipment listed for use in Sydney Water’s area can be used, so check before you buy.
- Other approvals. The site also needs its development approval or complying development certificate in place.
A recent grease arrestor installation
Bankstown, July 2026: a 1,500 litre grease arrestor for a restaurant
An office building was being converted into a quick-service restaurant. A new 1,500 litre grease arrestor went in underground in the car park, and in the basement we set up trade waste and sewer pump-outs. The fit-out also included a new connection to the gas main. Read about the project.
More fit-outs on our commercial plumbing page.

“Excellent service by Dave and Luke. Very friendly and professional boys. Arrived on time. Looked at the issue thoroughly and explained everything in detail and gave options on what to do. Would recommend anytime.”

How a grease trap installation works
Call 1300 301 354 or book online. Tell us about the business, the kitchen and whether you have Sydney Water approval yet.
We check the site and the approval conditions, then quote a fixed price. Work begins only when you say yes.
We install the trap, connect the kitchen and test the lines.
Pump-outs are then done regularly by a liquid waste company.
Food businesses that need a grease trap
- Restaurants, cafes and takeaway food outlets
- Function centres and caterers
- Butchers, delis and retail bakeries
- Child care centres, and school, hospital and nursing home kitchens
- Home-based food businesses that prepare food for sale
Cleaning and pump-outs
Grease traps are emptied by liquid waste companies, not plumbers. If the kitchen drains slow down or the trap smells or overflows between pump-outs, call us to check the lines and the trap’s fittings.
What does a grease trap installation cost?
The price is fixed before any work starts. It depends on:
- The size and type of trap your approval needs.
- Above or below ground. An underground arrestor means excavation and concrete work.
- The distance from the kitchen to the trap.
- Access for the pump-out truck and for our equipment.
Checking the job and pricing it is free on weekdays between 7am and 5pm, when there is no call-out fee. Book online and you’ll save $50, once you accept the quote.
