Ballymore Eustace Water Treatment Plant Upgrade

Uisce Éireann is upgrading the Ballymore Eustace Water Treatment plant to benefit 1 million customers.

Uisce Éireann, working in partnership with Dublin City Council, has commenced works to upgrade the Ballymore Eustace Water Treatment Plant. This project will benefit approximately one million customers, ensuring the continued delivery of a clean, safe drinking water source. Glan Agua Ltd. is delivering the project on behalf of Uisce Éireann.

The Ballymore Eustace Water Treatment Plant was the site of a water quality incident in August 2021 where the disinfection system at the plant failed. Emergency rectification works were carried out directly following this incident in order to ensure public water supply would not be interrupted in the area, however more upgrades are required to ensure continued compliance with drinking water regulations and reduce the risk of water quality issues in the future.

The completed upgrades will modernise and improve the water treatment process at the plant, ensuring raw water continues to be treated to the water quality standards as required by the European Union Council Directive and Regulations. 

The upgrade works carried out as part of this project will:

• Ensure the continued delivery of safe, clean drinking water to residents and businesses in the Greater Dublin Area.
• Improve water quality and water treatment standards for the future.
• Ensure compliance with current drinking water quality regulations.

The works as part of this project focus on the filtration system and include:

• Upgrade of 10 filters and associated filtration systems;
• Upgrade of electrical and control systems within the filter building;
• Upgrade of the filter building;
• Works to ensure optimal health and safety standards within the filter building

The upgrade works began in January 2023, and are due for completion in mid-2025.

We will endeavour to keep stakeholders updated as this project progresses.
