How Does A Grease Trap Or Grease Interceptor Work?


Call  01 450 9778 for grease trap sales, service, and maintenance enquiries

The buildup of waste in the drainage system can cause some serious and expensive clogs. For this reason, grease traps (or grease interceptors) are designed to hamper Fats, Oils, and Grease (FOG), solid waste material, and debris that creep into the drainage system of municipal or privately owned on-site sewerage systems. 

How Does Grease Trap Work?

The use of grease traps dates back from the Victorian days of 1800’s. Today, almost after 100 years, the technology of grease trap has not changed essentially.

Grease traps act like a retention chamber. They are plumbing devices used to stop most FOG (fat, oil, and gases) and solids so that they do not enter into the waste water disposal system, and the water component can pass through it. When FOGs and solids are accumulated, they naturally flow up to the surface of the water, and get ‘trapped’ by the grease trap. For the grease trap cleaning to be efficient, it should be cleaned at regular intervals. The FOG waste should be collected by professional licensed waste contractors, and dumped off at facilities that are built for the disposal of such waste (licensed facility). By law, grease traps should be emptied when the grease sludge is filled by 25% in the tank.  Commercial grease traps are used in kitchens of restaurants or food service departments.

FOG Programme

Many cities of Ireland are increasingly facing the issue of drain blockage in the public drainage systems caused by FOGs. This results in increased environmental pollution, such as flooding of dirt on the premises/street, and a foul smell in the atmosphere. For this reason, the capital of the country, Dublin has initiated a Programme in 2008, known as the Dublin City Council’s Fat, Oil, and Grease Programme. It is targeted towards controlling the FOG of the public drainage systems, by imposing a license that makes it obligatory to comply with the conditions of the FOG Programme, such as maintenance of commercial grease trap, appropriate disposal of the waste lubricants, size of the grease trap, and the amount of FOG that can be disposed. 

If you want your grease interceptors to be effective, you should install units that are properly sized, constructed, and maintained efficiently so that it can easily be pumped by waste haulers. More so, for a healthy grease trapper, ensure that you keep it maintained by performing weekly/monthly/quarterly cleaning schedules by professionals with quality standards.

Therefore, maintenance of grease traps (or interceptors) is essential. If more spent FOG is reserved in the grease traps for a long period of time, the efficiency level of the grease trap may diminish.

What is Drain Inspection Survey?

What’s that nasty smell in your kitchen?

Why is the water not running away through the drainage, like it should?

Drain inspection survey?—What is that!

It’s not as filthy, as it sounds!

In the modern world, it is commonly known as the CCTV pipeline inspection or drain survey. The purpose is simple—an inspection of your home’s drainage pipes, in order to see if there are, or will be any potential problems. If you are planning to move to a new house, we recommend you get the drainage system checked so as to save you some serious money in the future.

CCTV Drain Surveys

CCTV drain surveys use modern technology to explore faulty pipes and sewers by sending a camera in the core area of the blockage.  A locator is sent along with the camera that records the problem area.  The images received by professionals help in identifying reliable and consistent information that helps in giving recommendations for a better job.

Blockage inspection is not the only purpose of the CCTV inspection survey; they are fundamental in the maintenance services as well as in the decision to invest in a property.  

The task is certainly not on the to-do list of the house owners. So, we recommend you contact a specialist or a professional and schedule a drainage inspection survey on the hidden drainage areas of the house to unblock the drain. A drain survey would cost you from as low as €100, bringing you peace of mind and saving potential cost due to drainage issues.

By calling a professional drain cleaning company, you won’t have to worry about harsh chemicals being used for drain unblocking, and you can be confident that the blockage will be removed completely and drain tested with guarantee

Is it Possible to Prevent drain blockages in the Future?

You can make sure that clogs do not build up as quickly after drain cleaning by maintaining your drains. Some helpful tips to prevent future clogs:

  • Keep a Check on things that go down the drain – To maintain your drains, it is important to make sure only soft things and water-soluble materials go down the drain. Solid food particles and oil or grease should not go down the drain.
  • Install Protective Screens on your drains – To prevent hard substances or water-insoluble material from going down the drain, it is a good idea to install protective screens over your drains. These screens trap solid materials and prevent them from passing down the drain.
  • Remove Sink Stoppers and Clean Regularly- In the bathroom, remove the sink stopper and clean it regularly. Avoid throwing your hair down the sink or in the bathtub or shower drain to avoid clogs. Furthermore, don’t flush toilet paper towels down toilets

By following these tips, you can make sure your drains work efficiently and prevent opportunities for drain blockages to develop. It is also a good idea to get your drains cleaned on a regular basis by a professional drain cleaning company. Needless to say, without proper maintenance, pesky clogs can sneak up on you when you least expect them and you wouldn’t want that. Would you?

Drains are the veins of your building and home. Be careful what you put down.
