Roundstone Sewerage Scheme

Wastewater Project

Working to eliminate the discharge of raw sewage in Roundstone Bay.

Irish Water plans to deliver the Roundstone element of the Galway Untreated Agglomeration Study (UTAS) project. This project will stop the discharge of the equivalent of 645 wheelie bins of untreated wastewater being discharged directly into Roundstone Bay each day.

The existing wastewater network was originally constructed using clay pipes in the 1920s. Wastewater from the village is currently collected in existing sewer system and is discharged with no treatment in three separate locations into Roundstone Bay.


News and updates

Consultations have been on-going with all landowners identified on the proposed scheme. Irish Water was unable to acquire consent to all of the required wayleaves and lands on a voluntarily basis. Given the importance of the project to the wastewater infrastructure, Irish Water has now submitted a Compulsory Purchase Order to An Bord Pleanála to acquire the necessary lands and wayleaves.

In addition to the land acquisition process, Irish Water will be seeking planning permission for the Roundstone Sewerage Scheme in 2020. The timeline for commencement of works is subject to statutory approvals.
