Frequently Asked Questions

What is a Grease Trap?

A grease trap (also known as a grease interceptor) is a plumbing device designed to trap or intercept grease and food waste before it enters a waste water disposal system and public sewers. 

What are my Options?

There are two types of grease traps – electric and passive.

  • Electric grease traps use a heating element to skim surface FOG (fats, oils & grease) into a removable receptacle. They are typically situated indoors, under sinks and require daily cleaning and maintenance. 
  • FOG in a passive grease trap rises to the surface while waste food sinks to the bottom. Only greywater exits the trap. Passive traps can be made to measure and are installed outdoors, indoors, above ground or below ground. They require no maintenance or intervention from staff.  

Why do I need a Grease Trap?

There are two reasons why all Food Service Establishments need a grease trap.

  • It prevents liquid FOG (fats, oils & grease) from entering your plumbing system.
  • It is a legal requirement to restrict your FOG from entering the public sewer.

 

What Should I Consider Before Buying?

  • Will my grease trap pass an Irish Water inspection?
  • Is it 100% sealed to prevent malodours & leaks?
  • Will my staff have to maintain and clean it?
  • What is the manufacturer’s life expectancy?
  • What are the maintenance and running costs?

It pays to do some research. Ask other food operators to share their experiences and ask your supplier to provide as many references/testimonials as possible. Then, take the time to speak with some of them.  See More.

Correct Sizing –

A Legal Requirement

Why is Correct Sizing Important?

An undersized grease trap will not separate grease correctly as hot water from appliances will simply wash liquified FOG’s through the unit where it will later cool and solidfy in pipes and drains.

Sizing a grease trap correctly requires a skilful assessment of the food service establishment. Critical information such as water temperatures, flow rates, meals served per day etc. play a significant part in determining the volume of the unit.

Investing in a non-compliant or off-the-shelf grease trap can prove costly and disruptive as Irish Water Inspectors can insist on it being replaced. It pays to do a little research beforehand.

Grease traps manufactured outside of Ireland that do not carry the relevant NSAI or CE certification are not permitted. 

Do I need to Inform Irish Water prior to Installing A Grease Trap?

Yes. Irish Water requires food operators to provide sizing and design details when installing or replacing a grease trap. However, we provide this as a free service. Prior to fabrication and installation, we submit an application to Irish Water on your behalf.

We ensure that all your compliance obligations have been satisfied and we will assist you in applying for a Trade Effluent FOG Licence. What is a Trade Effluent FOG Licence?

How Will I Know if my Grease Trap is Sized Correctly?

As a Local Authority approved supplier we will provide a sizing calculation in accordance with I.S. EN 1825 Parts 1 & 2. This is an important document as Irish Water Inspectors will ask to see it during their routine inspections.

An accurate sizing calculation cannot be provided without a detailed survey of the premises.

How the BIOTRAP® Works.

As wastewater enters the BIOTRAP® the internal stainless steel baffles reduce the flow allowing the water to cool quickly. FOG (fats, oils & grease) then rises to the surface while food particles sink to the bottom.

Our Irish Water approved bacterial additive (not enzymatic) is automatically dosed into the unit each evening via a timed dosing pump. The micro-organisms in FAT ATTACK® break down FOG (fats, oils & grease) and digest all solid waste on contact which keeps the BIOTRAP®, as well as drains and pipes free-flowing and functioning like new.

There’s no moving parts, filters or bags to replace. BIOTRAP® requires no daily maintenance by staff, consumes zero electricity, and can be retrofitted in almost any kitchen (above or below ground). With a 25+ year life expectancy* and a 100% airtight design, BIOTRAP® is the most hygienic and cost-effective interceptor on the market.

  • Zero Smells or Leaks 
  • Zero electricity costs
