Urban Waste Water Treatment

Wastewater is a term that is used to describe waste material that includes industrial liquid waste and sewage waste that is collected in towns and urban areas and treated at Urban Wastewater Treatment Plants (UWWTPs).

A system for the licensing or certification of Waste Water Discharges (WWD) from areas served by Local Authority sewer networks was brought into effect under the Waste Water Discharge Regulations, 2007. This framework ensures that the urban wastewater treatment plants that are operated by the Local Authorities are regulated by the EPA.

The European Council Directive 91/271/EEC concerning urban waste-water treatment was adopted on 21 May 1991. Its objective is to protect the environment from the adverse effects of urban waste water discharges and discharges from certain industrial sectors (see Annex III of the Directive) and concerns the collection, treatment and discharge of:

  1. Domestic waste water
  2. Mixture of waste water
  3. Waste water from certain industrial sectors

All discharges to the aquatic environment from sewerage systems owned, managed and operated by water service authorities will require a waste water discharge license or certificate of authorisation from the EPA. The authorities are required to apply to the Agency for a license or certificate of authorisation by set dates depending on the population equivalent of the area served by the sewer network.

The UWWTPlant_Locations_06022015.shp is an ESRI Shapefile of (point data). This dataset contains 1085 urban waste water treatment plants.

The urban waste water treatment plants shapefile shows the locations of the sites as submitted by the Local Authorities.

A RegCD field is included to show the site's individual code when the site was registered and licenced by the EPA.

The data includes site name, address, including townland and Local Authority responsible for the site, as well as agglomeration type and licence status and date.

The UWWTP_Compliance_2006_2014_13012016.xlsx contains the latest Status Compliance (2014), as well as historical status data (2006, 2007, 2008, 2009 and 2012 where available) for 643 of the UWWT Plants.
