Whitegate/Aghada Sewerage Scheme

Wastewater Project

Irish Water is progressing plans for the construction of a new wastewater treatment plant and a contractor has now been appointed.

Irish Water, working in partnership with Cork County Council, has commenced works on the Whitegate-Aghada Sewerage Scheme in Co. Cork. This project involves the construction of a new wastewater treatment plant and sewerage infrastructure and will eliminate the discharge of untreated wastewater from the Whitegate and Aghada areas into Cork Harbour. Glan Agua is delivering the works on behalf of Irish Water.

In Progress

What is involved as part of this project?

The scheme will include the following:

  • A new wastewater treatment plant at Ballytigeen, which will serve a population equivalent of approximately 2,500.
  • A 310m marine outfall pipeline to safely discharge. treated wastewater to the sea near White Bay to the South-West of Whitegate.
  • Construction of 1400m of new sewer pipelines and 3,500m of rising mains to transport untreated wastewater to the proposed new wastewater treatment plant.
  • Construction of 3 below ground wastewater pumping stations near Rostellan Memorial Park, the pier in Lower Aghada and Main Street in Whitegate.

What are the benefits of this project?

The new wastewater treatment plant will bring benefits to Whitegate and Aghada including:

  • Better health and integrity of the environment.
  • Improved water quality in Cork Harbour.
  • Protection of recreational waters for swimming, surfers, fishing, boating and sightseeing.
  • Cleaner water will enhance local amenities and a platform for social and economic development, by protecting the local bathing waters and shellfish waters in the area.
  • New wastewater treatment plant, sewer pipes and pumping stations sized to accommodate future population growth.
  • Ensure compliance with national and EU regulations relating to the treatment of wastewater.

We’re working to eliminate raw sewage discharges in Ireland

  • Work is now complete in 18 areas around the country where there was no sewage treatment before. 60% of raw sewage is now being treated for the equivalent of 100,000 people.
  • This year we have 15 locations under construction across the country, prioritising the areas where it can make the biggest impacts first.
  • We are on track to eliminate the majority of raw sewage discharges by the end of 2025, with a total investment of €700 million.
  • In Cork, works in Castletownbere, Inchigeelagh and Whitegate-Aghada are underway; and works planned for Castletownshend and Ballycotton are due to commence this year, 2022.
