Ballyvaughan Sewerage Scheme

Wastewater Project

This project is needed to stop untreated wastewater being discharged directly into the sea at Ballyvaughan Bay. Ballyvaughan is a busy village with many pubs, restaurants, shops, B&Bs and other amenities including boating, fishing, scuba diving and other sea activities.

The practice of discharging untreated wastewater to the sea is no longer acceptable and Irish Water intends to rectify this problem by constructing a new Wastewater Treatment Plant, pumping station and sewer pipes.



  • The proposed WWTP will improve the water quality in the receiving waters by achieving the required discharge requirements as set out in the Urban Waste Water Treatment Directive
  • Cleaner water will enhance Ballyvaughan’s amenity value and act as a platform for social and economic development
  • The new pipes, pumping station and treatment plant have all been sized to accommodate an increase in the local population. 
  • The project will ensure that the water quality standards set down by regulatory bodies will be achieved


  • Construction of a new wastewater treatment plant that will serve a population equivalent of 900
  • Construction of a new terminal pump station with storm water storage
  • Sewer pipelines to bring untreated wastewater to the WWTP, and treated water to the existing outfall pipe
  • The existing outfall pipe will safely discharge the treated wastewater to Ballyvaughan Bay

Irish Water is progressing the design stage of the project. A number of options previously presented to the public in 2019 are currently being reviewed. Irish Water will further engage with stakeholders regarding the progress of the project in the coming months.  

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.
