What Exactly is a Grease Trap and How do I keep it Clean


All commercial kitchens should be fitted with a grease trap, which is a device to catch the grease and scum that runs down the many sinks you have in your kitchen. As you can imagine, all sorts of things end up down the sinks, with dirty water from mopping the floor and food waste that is very difficult to manage, and without regular cleaning, your drains will surely become blocked. There are three main types of grease traps used in commercial kitchens today, which are as follows.

  1. Under the Sink Units – Smaller grease traps would typically be fitted directly under a two or three sink unit and are designed to catch grease and debris as it passes through, ensuring that the drains are not contaminated with sludgy grease, which is something that will surely cause a blockage. The size of the grease trap tank would depend on the volume of the sinks it is protecting, and you should have these cleaned out regularly by a third party provider, and the work should be carried out when the kitchen is not in use.

  1. In Ground Grease Interceptor Tank – This is the most common type of grease trap for a commercial kitchen, and would have a capacity of 500 – 2,000 gallons, depending on the size of the kitchen. These usually have a manhole, which can be levered off with a crowbar and that gives you access to the interior. There is affordable grease trap cleaning in Sydney, and to be honest, it is wise to outsource this cleaning to a specialist company, and they would undertake the cleaning at specified intervals, ensuring that there are no blockages.

  1. Grease Recovery Devices – These are designed to recycle a portion of the grease and the system works automatically, and that means there is no need to have the trap cleaned out. The oil that comes from the deep fat fryers can be recycled with such a system, although most commercial kitchens would use an in ground tank, as this would have been installed when the kitchen was constructed.

Cleaning out a grease trap is not something to tackle yourself, and the larger underground tanks can be emptied with a special vacuum machine, which is something a professional outfit would have. If your kitchen grease traps are in need of cleaning, there are online specialists who will be happy to add your kitchen to the long list that they regularly maintain, and with an agreed schedule, you can forget about blocked drains. Large commercial kitchens would have several grease traps and the cleaning company would likely have a truck that can suck out all of the grease under pressure. This special device makes the job much cleaner and easier, and that’s why you should always leave this to the professionals.

Whatever your commercial kitchen needs, an online search is sure to reveal the whereabouts of a local company that can carry out essential grease trap cleaning, which is an essential part of commercial kitchen maintenance.
