Water Plant gets €10.5m upgrade to serve 42,000

IRISH Water and Dublin City Council marked the official start of works on the €10.5 million upgrade at the Ballyboden Water Treatment Plant.

The €10.5 million investment includes the construction of a covered reservoir to store 16 million litres of treated drinking water, the decommissioning of the existing open storage reservoir at the site, and work to upgrade the disinfection process at the treatment plant.


This new covered reservoir is essential to safeguard the quality of the drinking water for over 42,000 people.

The existing Ballyboden site contains an open water reservoir which stores treated drinking water prior to its distribution to customers.

This is one of the last remaining open service reservoirs of treated drinking water of its kind in Europe. Treated drinking water exposed to the environment presents a contamination risk to supply.

Coffey Construction Limited are carrying out the works on behalf of Irish Water.

Speaking at the sod turning, Michael Tinsley, Irish Water’s Infrastructure Portfolio Manager, said: “This upgrade to the Ballyboden Water Treatment Plant is a priority project for Irish Water.

"It will ensure that a secure and sustainable supply of water is provided to over 42,000 people in Dublin City, Dún Laoghaire-Rathdown and South Dublin County.

"Covering the reservoir will safeguard the quality of drinking water for the community and provide a long-term solution for the safe and sustainable management of the water supply."
