Liscannor Sewerage Scheme

Wastewater Project

Irish Water is commencing works to eliminate raw sewage being discharged into Liscannor Bay.

Irish Water, working in partnership with Clare County Council, is progressing the construction of a wastewater treatment plant in Liscannor to end the discharge of raw sewage to Liscannor Bay. Works have now commenced on site and EPS Group will carry out the project on behalf of Irish Water.

Wastewater in the Liscannor area is currently conveyed to a septic tank system before being discharged into Liscannor Bay. The discharge of inadequately treated wastewater threatens water quality, detracts from the amenity value of Liscannor and does not comply with EU regulations relating to the treatment of wastewater.


What is involved in this project?

  • The construction of a new wastewater treatment plant which will serve a population equivalent of 1,790;
  • The construction of a storm water storage tank as well as a new pump station with emergency storage;
  • The construction of approximately 1.3km of sewer pipelines; and
  • Connection to the existing outfall pipe to safely discharge treated wastewater into Liscannor Bay.

What are the benefits of this project?

The proposed new wastewater treatment plant will bring benefits to Liscannor, including:

  • Better health and integrity of the environment;
  • Improve the water quality in Liscannor Bay;
  • Protection of recreational waters for swimming, surfers, fishing, boating and sightseeing waters;
  • Facilitate growth and development in the area;
  • Cleaner water will enhance environmental amenity value of the Liscannor area and act as a platform for social and economic development;
  • Ensure compliance with national and EU regulations relating to the treatment of wastewater.

How can I connect into the new sewerage scheme?

Any person or business wishing to get a new connection to public wastewater collection infrastructure must contact Irish Water. You can make a pre-connection enquiry in order to establish whether a connection to the public network is feasible, where the connection can be made and any associated charges.
