Clarecastle Sewerage Scheme

Wastewater Project

Irish Water has commenced works on the Clarecastle Sewerage Scheme.

Irish Water, working in partnership with Clare County Council, is commencing works on the Clarecastle Sewerage Scheme, to end the discharge of raw sewage into the River Fergus and Shannon Estuary from Clarecastle. Shareridge is delivering the works on behalf of Irish Water.

Wastewater from the public sewer network in Clarecastle is currently discharged untreated into the River Fergus and the Shannon Estuary. The discharge of untreated wastewater is unacceptable, threatens water quality and detracts from the amenity value of the area.

In Progress

What is involved with this project?

The scheme will involve the design and construction of the following works:

  • Installation of new below ground infrastructure at the site of the existing Quay Road Pump Station
  • New rising main pipeline along Quay Road, Barrack Street and the Ennis Road, to transfer sewage from Quay Road Pumping Station for treatment at the existing Clareabbey Wastewater Treatment Plant
  • Existing outfall from Quay Road Pump Station will continue to be used as an emergency storm overflow.

What are the benefits of this project?

The provision for treatment of wastewater from Clarecastle will ensure:

  • Improved water quality in the River Fergus in compliance with national and EU regulations relating to the treatment of wastewater
  • Enhanced environmental amenity of the Clarecastle area
  • Protection of recreational fishing water

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.

Next Steps

  • Works commenced in Spring 2022 and temporary traffic management will be required along public roads.
  • We will endeavour to keep the local community informed as this essential project progresses.

We’re working to eliminate raw sewage discharges in Ireland

  • Work is now complete on 18 areas around the country, where there was no sewage treatment before.
  • Over 60% of raw sewage is now being treated.
  • This year we have 15 locations under construction across the country, prioritising the areas where it can make the biggest impact first.
  • We are on track to fully remove the vast majority of raw sewage discharges by the end of 2025, with a total investment of €700 million.
  • In Clare, works are underway in Liscannor, Kilrush and Clarecastle; and works planned for Ballyvaughan and Kilkee.

Irish Water would like to thank the community in Clarecastle for their cooperation on this essential project.
