Coffey Water Completes Ahascragh Sewerage Scheme

Coffey Water Ltd has completed works on the Ahascragh Sewerage Scheme which will put an end to the discharge of raw sewage into the Bunowen (Ahascragh) River.

The company completed the €3.5m investment on behalf of Uisce Éireann on time and under budget. Works involved the construction of a new wastewater treatment plant which will serve a population equivalent of approximately 470. It will benefit the health, the integrity of the environment whilst improving the water quality for all.

As part of this project, a new wastewater treatment plant was included. Additionally, the project included the decommissioning of the outdated and insufficient wastewater infrastructure previously used for raw sewage treatment.


Storm water overflow improvement works were completed to ensure compliance under the relevant standards and upgrade works were also completed to the existing main pumping station including pumps, mechanical plant and the provision of a new storm water storage tank.

Uisce Éireann's Paul Fallon paid tribute to the team who brought the significant project to life, he said:

"We are delighted to have delivered this important project on behalf of the local community in Ahascragh, and the people of Galway.

"The Ahascragh Sewerage Scheme has ended the discharge of untreated wastewater into the Bunowen River. It will improve water quality in the Bunowen River and protect recreational waters for swimming, fishing, boating, and sightseeing; as well as protecting the integrity of the local environment. In addition to enhancing local amenities, the new wastewater infrastructure, which has been sized to accommodate future population growth, will provide a platform for social and economic development."
