Trust the commercial drainage experts at The Plumbing Paramedics

Fats, oils and grease (FOG) might seem harmless going down the drain, but in large volumes, they can wreak havoc on commercial plumbing and the public sewer network. Without a functioning grease trap, your sinks can back up, wastewater can overflow, and your business could be slapped with fines or shutdown notices from Sydney Water.

Why Grease Traps Matter in Your Business

Sydney commercial kitchens, from cafes to food courts, require properly sized and council-approved grease traps. The Plumbing Paramedics are licensed plumbers experienced in all aspects of commercial grease trap installation, connection, backflow prevention, and maintenance access, so your system is both legal and reliable.

What Is a Grease Trap?

A grease trap (also called a grease interceptor) is a plumbing device that captures fats, oils, grease and solids (FOGS) from wastewater before it enters the sewer. Water flows into the trap, where grease floats to the top, solids sink to the bottom, and the cleaner water flows out to the wastewater system.

The design is simple, but effective. And in NSW, it’s not optional. Grease traps are required by law for most commercial food premises.

Sydney Water Approval: All grease traps must be approved by Sydney Water prior to installation. See grease trap request form There is also a list of approved grease traps to select from – See the grease trap list

We recently experienced a plumbing emergency with water leaking from our ceiling and called Plumbing Paramedics for help. Kyle and Josh arrived promptly and quickly identified the source as a burst pipe. They were professional and knowledgeable throughout, taking the time to clearly explain the issue before proceeding, and completed the repair along with installing a new pressure valve in under 90 minutes. As a family with young children, we greatly appreciated their efficiency and the peace of mind their work provided. We highly recommend them and will use them again!

Highly recommend The Plumbing Paramedics! They arrived on time, quickly changed the faulty sink mixer in our kitchen; disconnected, removed the the leaking down pipe and replaced it with a new one. They had them repaired in no time. They left the work area completely spotless. Professional, polite, and skilled—will definitely use them again for any future plumbing needs.

Grease Trap Installation Services We Provide

  • Council-compliant grease trap installation
  • System design for both new builds and kitchen upgrades
  • Commercial plumbing compliance and backflow prevention
  • Grease trap sizing and location planning
  • Coordination with Sydney Water & trade waste permits
  • Ongoing grease trap maintenance and cleaning plans

Whether you run a small takeaway or a large production kitchen, we help you choose the right trap and make sure it’s installed to meet all AS/NZS 3500 plumbing and Sydney Water trade waste standards.

Choosing the Right Grease Trap: Size and Location Matter

Grease traps must be sized based on wastewater volume, appliance output, and kitchen size. The minimum size required is 1000 litres, but many businesses need larger systems.

Installing the trap close to the kitchen is best, the longer grease travels through a pipe, the more likely it is to cool, solidify, and block the line. The trap must also be easily accessible for vacuum pump trucks.

Poor location or undersized traps = costly retrofits later.

Frequently Asked Grease Trap Questions

Sydney Water requires a minimum 1000-litre grease trap for most commercial kitchens. We assess your business size, number of sinks and dishwasher output to size the trap properly.

Yes. Sydney Water must approve both your trap size and location before installation. We handle this process on your behalf.

As close to the kitchen as possible, with direct access for cleaning. Avoid long horizontal pipe runs that allow FOG to cool and clog.

Yes. Backflow prevention is mandatory with commercial grease traps. We install appropriate devices based on your risk level and water supply.

Operating a commercial kitchen without a grease trap can lead to Sydney Water fines, sewer damage, and closure orders. It is not optional.
