Grease Trap Cleaning
Wigan, Preston, Leyland, Chorley, Lancashire

Do you Require grease trap cleaning for commercial kitchens in Lancashire? Our grease cleaning and removal service prevents grease trap blockages and fire risk.

Commercial grease traps are commonly found outside the main building. For example, look at the ground near the wall surfaces by your kitchen's dishwashing area- they look just like a maintenance hole or a septic tank cover. If your kitchen has a basement, you might sometimes find your grease trap down there to keep away from the frost.


Grease traps should be cleaned every 4-6 weeks. An unmaintained grease trap won't stop grease waste from going into the sanitary sewer or septic system. 

Grease blockages are disastrous for restaurants, as well as posing as a fire hazard. Disinfecting a restaurant with grease blockages can close your establishment down for at least two days.

Attempting to clean your grease trap could turn into your biggest nightmare. Instead, employ a credible cleaning service specialist to make sure the grease waste is disposed of responsibly.

Cleaning Procedure

Before you cleanse your grease trap, wait for the water to cool down inside the catch. Then, wait 10 minutes after emptying the wastewater from the 3-compartment sink or automatic dishwasher.

  • First, remove the lid. Pay close attention as most grease traps are under the 3-compartment sink.
  • Put a ruler into the grease trap and note how many inches of grease is in the catch. This should be recorded in a FOG report supplied by the EPA.
  • Eliminate any water from your grease trap, either with a scoop or a small pump. Set this water aside.
  • Start digging out the grease from your trap. You can use a bucket, a shovel or another heavy-duty scooper.
  • Scrape the bottom, sides and lid to remove excess grease. This will help prevent accumulations from other debris you haven't released.
  • Thoroughly clean parts of your trap and flush the screens out.
  • Put the water from Step 3 back into your grease trap.
  • Properly reinstall any removed parts and replace the lid.

Fat Trap Emptying & Waste Disposal

It is vital to regularly clean, and service fat traps. Not only is it essential to ensure that they function fully, but over time, fat traps can become hazardous and toxic. During the rotting process, food waste that can sometimes get deposited in fat traps starts releasing toxic gasses, such as sulphate. When combined with water, the sulphate can attack and react to concrete and mild steel. If it is left unclean and unserviced, the fat trap would need to be replaced. 

It is both costly and time-consuming to replace a fat trap. Therefore it is more economical to have a regular maintenance schedule.

What is the Importance of a Grease Trap?

Grease traps are a vital part of any food processing plant or commercial kitchen. A grease trap will help with the management of excess (FOG) fats, oils and grease. 

They trap the FOG and prevent them from entering the drain and underground sewerage system. If left to disperse in the drainage system, they can cause potential blockages, like fatbergs. 

Fatbergs are rock-hard masses of solidified fat and can cause severe damage to the underground sewerage system.

Grease will build up quickly inside the traps, and this makes them ineffective to trap grease.

Is Grease Trap Waste Controlled Waste?

Yes, all waste from grease traps is classified as controlled waste. Therefore, either an Environmental Health Officer or The Environment Agency require you to provide evidence that your grease trap has a regular clean and the removed waste is disposed of by a registered waste carrier company. 

Failure to produce the correct documentation can result in prosecution or a fixed penalty. The local authority has the power to carry out any work required and recover their costs in cases of the owners' default. 

How do you Prevent Drain Blockages and Fatbergs?

The build-up of (FOG) fats, oils and grease can enter the drainage system. Having your grease trap emptied regularly will prevent this from happening. 

It is also good to use a biological solution regularly to prevent the build-up of grease, fats, and oils from entering the drainage system. The solution will safely break down any build-up between your regular cleaning and waste removal and the grease management programme. Before using a biological solution, make sure it is environmentally friendly.
