Trade Effluent to Sewer Discharge Licence

Irish Water are responsible for the issuing of discharge licences for effluents discharged to sewers under the provisions of Section 7 of the Water Services (No.2) Act 2013, (which transfers part of the functions of the local authorities to Irish Water).  A licence which was issued under Section 16 of the (Water Pollution Act) 1977 shall continue to be in force for the unexpired period of the licence, as if granted by Irish Water. 

Whether your business is a small restaurant or a large multinational manufacturing industry, if it generates a wastewater which is discharged to a sewer, a discharge licence is required with very few exceptions.

In order to obtain a licence to discharge trade effluent to sewer a valid application must be submitted to Irish Water.  The discharge licence application form supplied by Irish Water must be accompanied by all relevant submissions, plans, documents and other relevant information to support the application, including:

  • Site Drawings
  • Site process schematics
  • Planning permission details
  • Effluent quality, discharge volume and flow rate details
  • Proposed effluent treatment details, ie demonstrating how you will comply with licence conditions.

Trade Effluent Discharge to Sewer Licences set out conditions that must be complied with and may include:

  • The nature, composition and volume of the trade effluent discharge
  • The method of treatment, the location of discharge and the periods during which discharge may be made
  • The taking and analysis of trade effluent samples and the trade effluent records that must be kept 
  • Applicable charges for discharging trade effluent, as approved by the Commission for Regulation of Utilities (CRU).
