Inchigeelagh Sewerage Scheme

Wastewater Project

Works on the new sewerage scheme in Inchigeelagh have now commenced.

Irish Water, working in partnership with Cork County Council, has commenced works on the Inchigeelagh Sewerage Scheme. This €6.8 million investment involves the construction of a new wastewater treatment plant and sewerage infrastructure, which will eliminate the discharge of untreated wastewater into the River Lee. Glan Agua is delivering these works on behalf of Irish Water.

In Progress

What are the benefits of this project?

The new wastewater treatment  plant will bring benefits to Inchigeelagh including:

  • Better health and integrity of the environment.
  • Improved water quality in the receiving waters of the River Lee.
  • Enhanced local amenities and a platform for social and economic development.
  • New sewer pipes and a pumping station sized to accommodate future population growth.
  • Ensure compliance with national and EU regulations relating to the treatment of wastewater.

What is involved as part of this project?

  • A new wastewater treatment plant which will serve a population equivalent of 290.
  • Construction of a new below ground wastewater pumping station.
  • Construction of approximately 315m of new rising main to transport untreated wastewater from the pumping station to the proposed new wastewater treatment plant.
  • Construction of approximately 110m of gravity sewer to transport untreated wastewater from Cois Na Coillte to the proposed wastewater treatment plant.
  • A 45m long outfall pipeline to safely discharge treated wastewater to the River Lee.

Upcoming works

  • SAT Testing
  • Turning Flows
  • Tar to be placed on entrance road to WWTP
  • Permanent site Fencing to commence
  • Boundary wall installation to commence

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.
