Frequently Asked Questions

Will My Grease Trap Be Inspected?

Yes. Your grease trapping equipment will be inspected up to 4 times per year by a representative of Irish Water. Inspectors can call without notice and will ask to see documentation relating to the design, manufacture and maintenance of the grease trapping equipment.

What Does the Inspector Require?

Irish Water inspectors require the licensee to regularly monitor, maintain and document the compliance performance of each grease trap on their premises.

The following information should be retained for each inspection:

  • A copy of the sizing calculation for the grease trap 
  • A copy of the manufacturers CE accreditation
  • Design details showing volumes, flow rates etc. 
  • Dates & times of all maintenance records 
  • Waste disposal records from a licensed contractor 
  • Copy of a current Trade Effluent FOG Licence

Failure to present any of the above may result in a notification of non-compliance. 

What Is a Trade Effluent FOG Licence?

All FSE’s (Food Service Establishments) are legally required to apply for an annual Trade Effluent FOG Licence. This allows food operators to discharge their catering wastewater into the public sewer. However, if compliance with licensing requirements cannot be demonstrated for the previous year a current licence will not be issued. The premises will be informed of their non-compliance and given time to address the issues.

Under Section 16 (1) of the Public Health Act, the food operator is subject to criminal liability if they cannot demonstrate compliance with the conditions of their Discharge Licence.

How do I Apply for a Trade Effluent FOG Licence? 

    You can apply for a licence via the Irish Water web site:

    If you operate a restaurant, cafe, hotel, fast food outlet etc. you will need to apply for a Trade Effluent FOG Licence 

    If you operate a service station, dry cleaners etc. you will need to apply for a Trade Effluent Licence

    The cost is €380.00 per year made payable to Irish Water.
