• Any existing licence remains valid if the licence has not been reviewed or revoked, or
  • Any existing licence remains valid for a period of three years following cessation of the discharge of trade effluent to sewer

The existing licence is sufficient until such time as a licence review is required.

A licence review will be required if the following applies: 

  • If there is a change to the business/trading name

    • may alter the nature or composition of the trade effluent discharged to sewer
    • may alter volume or rate of flow of the trade effluent discharged to sewer
    • may alter abatement, treatment or recovery systems installed in connection with the trade effluent discharged to sewer
    • may alter the range of processes or activities giving rise to the trade effluent
  • There are continuous non-compliances with any conditions of the existing licence:
  • There is a change of a discharge to sewer location in an already licensed site
  • Both Irish water and the Licensee can initiate a licence review. To initiate a review please email dischargetosewer@water.ie quoting your current discharge licence number. Where Irish Water initiates the review the application fee is non-applicable
