Kilmore Quay Sewerage Scheme

Wastewater Project

Irish Water has commenced the construction of new wastewater infrastructure in Kilmore Quay.

Irish Water, working in partnership with Wexford County Council, has commenced the construction of a sewerage scheme in Kilmore Quay, which will end the discharge of raw sewage into receiving waters. John Sisk & Sons Ltd. are delivering the works on behalf of Irish Water.

Sewage currently entering the Kilmore Quay public sewer network is discharged without treatment to the Eastern Celtic Sea. The discharge of raw sewage is not sustainable as it threatens water quality and detracts from the amenity value of the coastal waters in the area.

In Progress

What is involved in this project?

The proposed scheme will involve the design and construction of the following works;

  • A new wastewater treatment plant that will serve the population equivalent of 850 people.
  • New below ground pumping stations with above ground kiosks.
  • Pipelines to transfer sewage from the pumping stations to the wastewater treatment plant.
  • A new treated wastewater pipeline to discharge treated wastewater from the new wastewater treatment plant to the existing discharge pipe.
  • Testing and commissioning of the works.

What are the benefits of this project?

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

  • Improved water quality around the quay, and wider harbour area;
  • Enhanced amenity value of the coastal waters;
  • Compliance with national and EU regulations relating to the treatment of urban wastewater;
  • Provision for future development within the area.

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.
