Discharge to Waters Enforcement

Waste Water Treatment Plants

Effective wastewater (sewage) treatment is an essential function of Irish Water.  Municipal sewage, i.e. sewage produced in a town or city, is high in both solids and nutrients, which if left untreated, can cause significant environmental pollution. The purpose of wastewater treatment is to collect and treat municipal sewage to an acceptable standard and to discharge the treated water to a suitable watercourse (e.g. a local river). It is therefore critical that the treated water does not negatively impact on the quality of the receiving waters. 


Offaly County Council on behalf of Irish Water operates 27 Waste Water Treatment Works throughout the County. The Waste Water Discharge (Authorisation) Regulations, 2007 (S.I. 684 of 2007) legislated for the EPA to issue Discharge Licences for  Wastewater Treatment Works serving a population equivalent of 500 or over and Certificates of Authorisation to those treating populations less than 500.
