Multimillion euro upgrade to Ballyboden Water Treatment Plant

10 July 2023

Major investment will provide safe and secure drinking water for over 42,000 customers across Dublin and GDA

Uisce Éireann, working in partnership with Dublin City Council, has commenced an €8.7 million project to upgrade Ballyboden Water Treatment Plant. The project will ensure the delivery of a safe and reliable drinking water supply for over 42,000 customers across Dublin and the Greater Dublin Area (GDA), providing improved water quality and ensuring compliance with EU drinking water quality regulations.

In 2018, a project which included the construction of a new 16 million litre covered reservoir and associated upgrades to the treatment plant was completed which facilitated the removal of the Ballyboden drinking water supply from the EPA’s Remedial Action List (RAL). As part of the project, and after almost 130 years serving communities across Dublin City, South County Dublin and Dún Laoghaire-Rathdown, the old, open water storage reservoir was decommissioned.  

The current project involves a programme of works to modernise and improve treatment processes at the plant, including upgrades to 5 filters and associated filtration as well as structural re-lining of a number of original concrete structures. This will ensure that the raw water entering the plant is treated to the highest standards before reaching customers’ taps, providing a safe and resilient water supply for Dublin and the GDA.  

Following on from these significant upgrades, a further programme of upgrade works will continue at Ballyboden Water Treatment Plant over the coming years to further improve and enhance operations at the plant. 

Speaking about the project, Martin Temple, Uisce Éireann said, “This project is one of a number of strategically important projects to increase the security and resilience of the drinking water supply across Dublin and the GDA. This important project will ensure the provision of clean, safe drinking water to homes and businesses for current and future generations."

Delivering several upgrades of this magnitude across the GDA while producing enough water to meet demand is challenging. We look forward to working closely with our colleagues in Dublin City Council and our contractors, Veolia Water Ireland, and together playing our part to meet this challenge and successfully delivering this project for these communities.”  

The project is being carried out by Veolia Water Ireland on behalf of Uisce Éireann, and is expected to be completed by March of next year.
