If you run a restaurant or cafe in Australia, you may have wondered how to clean out a grease trap. The process is pretty simple but you do require certain tools such as a suction liquids truck!

It should also be noted that you should not clean out a grease trap if you are not a professional. Grease trap cleaning is regulated by your local water authority and a schedule will be set as regards cleaning (see our blog on how often a grease trap needs to be cleaned).

In the Sydney metro, you can only select a company that arranges services through a registered transporter as monitored by Sydney Water. If you cleaned the trap yourself, it would not be counted by the water authority. As a result, you would surely be fined.

First, how does a grease trap work?

Before we begin discussing how to clean a grease trap, we first want to discuss how a grease trap works. This way, the readers can fully comprehend the following sections below.

How to clean out a grease trap

In the points below, we will cover the basic outline of how to clean out a grease trap. This will be what a reputable grease trap cleaning business will do each time you have a scheduled clean.


1. Turn the water off

The first step to knowing how to clean a grease trap is to turn off the water. A grease trap is a box of water varying in size from c. 60 litres up to 10,000 litres. When a trap is newly cleaned, it is 100 per cent full of water. Furthermore, it will gradually become full of grease and fat if left uncleaned.


2. Open the lid

This is the second step on how to clean a grease trap. Of course, they have to open the lid first before they can do anything. Just a reminder: open the lid carefully so as not to damage anything, especially the seals. Additionally, you – referring to the business providing the cleaning service – should also carefully analyse the removal and return of the parts.

The lid of a grease trap is often heavy and made from concrete or metal. The truck driver will carry special tools (e.g., crowbar, prybar, prise bar, etc. – however, you want to call it) to open the lid if it is an in-ground unit. There are also above-ground units and under-sink units for small traps.


3. Pump out the contents

The third step on how to clean a grease trap is to force out the waste. By using the suction hose from the truck, the driver will pump out the mixture of water and fats/oils, etc. from the trap. This is when a powerful suction hose comes in useful.

Most trucks have c.15m of the hose as standard.

4. Scrape down the sides

A good cleaning will involve the driver scraping down the sides of the trap (i.e., for any excess or built-up sediment).

Add additional water if excessively dirty. If the trap is not in a good state (e.g., if it has not been cleaned in a long time), the driver may need to add extra water and repeat the process as above.


5. Dispose of the liquid collected

The truck will empty the liquid at the waste facility.
