Following our investment in Ballyboden Water Treatment Plant

Irish Water, working in partnership with Dublin City Council, is delighted to announce that the drinking water supply for 37,000 customers in Dún Laoghaire-Rathdown and South Dublin has been removed from the Environmental Protection Agency’s (EPAs) Remedial Action List (RAL). The RAL is the list of ‘at risk’ water supplies.

The removal of the water supply from the RAL follows the construction of a new covered treated water reservoir and an upgrade to the disinfection process at Ballyboden Water Treatment Plant. The project represents a €10.5 million investment by Irish Water.

Construction of a new 16 million litre covered reinforced concrete reservoir

The Ballyboden Water Treatment Plant is located within a 25 acre site situated on Stocking Lane in Rathfarnham, Co. Dublin. The treatment plant included open storage for treated drinking water which presented a risk of contamination as the water supply was vulnerable to contact from wildlife and airborne materials. This project involved the construction of a new 16 million litre covered reinforced concrete reservoir on the existing site which eliminates any potential contamination risk of the treated water. Additionally, improvement have been made to the disinfection process to reduce water quality risks to a minimum. Coffey Construction Ltd. completed the works on our behalf, under the supervision of RPS Group.

Commenting on the investment, William McKnight, Irish Water, said: “The publication of the latest EPA RAL update confirming the removal of this water supply from the list highlights the focus and dedication of Irish Water and our Local Authority partners in ensuring the delivery of clean and wholesome water to homes and businesses. This investment will ensure a secure supply of water to over 37,000 people in Dublin City, Dún Laoghaire-Rathdown and South Dublin County. After almost 130 years serving Dublin City and County, the open reservoir at Ballyboden has been replaced with a more modern covered reservoir to adequately meet current requirements and the needs of future generations.”
