- 99.5% of water samples taken in 2020 were compliant, meaning public water supplies are safe to drink
- 58 Water Treatment Plants built or upgraded in 2020
- €450m invested in water projects
- Over 100,000 people removed from 'at risk' supplies in 2020.
December 15 2021 - 99.5% of samples taken in 2020 across Ireland's 740 public drinking water supplies are compliant for microbiological and chemical standards producing water that is safe to drink according to the latest Environmental Protection Agency (EPA) Drinking Water Report.
The report, published today by the EPA highlights the ongoing progress made by Uisce Éireann in reducing water supplies classed as being at risk by the EPA, with a further 11 supplies removed from the Remedial Action List (RAL) in 2020 benefitting over 100,000 people. This work continued throughout 2021, with an additional six supplies removed so far this year, benefitting over 660,000 people. As a result the population on the RAL reached its lowest ever figure by mid-2021 and Uisce Éireann is continuing with its plans to address all remaining supplies.
The scale of investment, the level of national planning and the ongoing delivery of projects and programmes by Uisce Éireann is demonstrated in the EPA report.
Key programmes such as the National Disinfection Programme, and the removal of the risk of THMs (Trihalomethanes) and Cryptosporidium in water supplies are ongoing and are vital to ensuring clean, safe drinking water throughout the country. In 2020, Uisce Éireann invested €450m in building or upgrading 58 Water Treatment Plants (WTP) including significant upgrades to the Lough Talt and Staleen WTPs which collectively addressed long running water quality risks for THMs and Cryptosporidium.
Further progress has been made in 2021 with significant upgrades completed at Leixlip Water Treatment Plant, at Stillorgan Reservoir, and at Vartry Water Treatment plant. These works will ensure over 1 million customers will receive a safe and secure supply into the future.
Commenting on the report, Katherine Walshe, Head of Environmental Regulation with Uisce Éireann, said: "Uisce Éireann acknowledges the report and the important work the EPA undertakes as the supervisory authority for public water supplies. Overall, in 2020 public water supplies were 99.5% compliant which is a world class level of compliance with the drinking water regulations. Given the size and scale of investment needed to upgrade water treatment plants and the wider water network, Uisce Éireann is very pleased to achieve such a high compliance rate for the Irish public.
"During 2020, we made major investments in new and upgraded plants as well as delivering improvement programmes at our plants to enhance the quality and consistency of supply.
"Our investment continues. We are advancing Drinking Water Safety Plans for all of our larger supplies, with a key emphasis on minimising risks from source to tap. We have engaged extensively and comprehensively with the EPA on this and will prioritise funding towards those schemes at highest risk.
"The report is clear, however, that much more remains to be done to secure water supplies into the future. Uisce Éireann has plans underway to work with Local Authorities and other delivery partners to further enhance our ability to manage public water supplies to the required standards as set out in the Drinking Water Directives. Uisce Éireann have also rolled out critical training to all Local Authorities to ensure alarms and controls are in place and are operationally effective to ensure public health is protected now and into the future."
Uisce Éireann is also making strong progress in reducing the number of long-term Boil Water Notices in place around the country. Since the establishment of Uisce Éireann, 263 Boil Water Notices have been lifted, benefiting approx. 1.8 million people. Where risks to water quality are identified through rigorous sampling and testing Boil Water Notices are issued in order to safeguard public health. In all instances immediate action is undertaken to address the underlying causes of the issue to enable the lifting of the notice as soon as it safe to do so. In some cases, this may take time as capital investment may be required to address a treatment deficiency. Uisce Éireann has addressed all long-term boil water notices that were in place before it was established, and the average duration of all subsequent notices is decreasing.
Uisce Éireann has been working in partnership with Carlow County Council, to address water quality issues across the county. We have built new drinking water infrastructure in towns and villages across the county, improving water quality and benefitting local communities. In addition, the largest water production facility in county Carlow is currently receiving an upgrade. The Carlow North Regional Water Supply Scheme with production at the Rathvilly Water Treatment Plant will bring a safer, more reliable water supply to a population of 9,783 in Carlow, west Wicklow and Kildare once complete and will promote social and economic development in the area.
Carlow Disinfection Programme
We're investing €65 million to upgrade and standardise disinfection systems across the country. The programme involves over 864 water treatment plants, pumping stations, and reservoirs across the country.
Delivering clean, safe drinking water is our top priority. Disinfection is an important part of the water treatment process. The disinfection progress kills disease-causing organisms in water.
The National Disinfection Programme ensures Carlow will continue to have safe and secure drinking water. We have been working with Carlow County Council to assess the water treatment plants in Carlow.
Disinfection systems at 12 plants are being upgraded and standardised. These sites include: The Parade (Bangelstown), Royal Oak (Bangelstown), Ballinkillin, Borris, Raheenleigh, Rathvilly, Oak Park (Carlow Town), Sion Cross (Carlow Town), Leighlinbridge, Old Leighlin, Tyllow and Bilboa Water Treatment Plants.
The programme involved assessing the condition and performance of all the sites. We then determined the disinfection systems that need to be upgraded. Works at the plants included upgrades to the:
- Chemical storage and dosing infrastructure
- Chlorine contact time provision systems
- Disinfection systems using Ultra Violet (UV) where required
- Monitoring instrumentation systems
- Control, telemetry and automation processes
The upgrade works carried out as part of this project have improved the security of drinking water for residents and businesses across Carlow, improved the disinfection systems and standards, future-proofed the security of supplies, provided improved control of the systems and ensured continued compliance with Drinking Water Quality Regulations.
Since 2014, Uisce Éireann has been working in partnership with Clare County Council, to address water quality issues across the county. We have built new drinking water infrastructure in towns and villages across the county, improving water quality and benefitting local communities.
By building this new infrastructure we have improved drinking water for over 1,700 people and facilitated the removal of 5 water supplies from the EPA's Remedial Action List.
We have prioritised our investment to improve drinking water quality for residents and businesses across Clare.
Uisce Éireann are making progress across our projects and programmes:
Clare Disinfection Programme - We are investing €65 million to upgrade and standardise disinfection systems across the country. The programme involves over 864 water treatment plants, pumping stations, and reservoirs across the country.
Delivering clean, safe drinking water is our top priority. Disinfection is an important part of the water treatment process. The disinfection progress kills disease-causing organisms in water.
The National Disinfection Programme ensures Clare will continue to have safe and secure drinking water. The Clare programme is now complete. Disinfection systems at 15 plants have been upgraded and standardised. We have also finished operational upgrades to public water supplies and pumping stations.
These supplies include: Ennistymon, Scarriff, Kiladysert, Corofin, Mountshannon, Feakle, Carron, Flagmount, Kilkeedy, Shannon/Sixmilebridge, West Clare and Turlough.
Contracts have been signed for the upgrades of three water treatment plants in Clare that are on the EPA Remedial Action List. Construction work is underway at Carron and New Doolough (West Clare) water treatment plants. Work on the third plant at Ballymacraven (Ennistymon) is scheduled to commence in 2023.
Since 2014, Uisce Éireann has been working in partnership with Cork City and County Councils, to address water quality issues across the county. We have built new drinking water infrastructure in towns and villages across the county, improving water quality and benefitting local communities.
By building this new infrastructure we have improved drinking water for over 23,000 people and facilitated the removal of 14 water supplies from the EPA's Remedial Action List to date.

Uisce Éireann are also making progress across other projects & programmes such as: Lee Road Water Treatment Plant - Investing approximately €40 million to upgrade the water supply for over 70% of Cork City. This project will provide much needed upgraded facilities to safeguard the water supply for Cork City. Once works are complete, the upgraded and modernised plant will provide a more secure water supply for the future of Cork City.
Eastern & Western Strategic Trunk Watermains - Uisce Éireann, working in partnership with Cork City Council, is working to improve the security of water supply across Cork City. These projects will increase security of supply and reduce leakage of large strategic mains in Cork City.
The Eastern Strategic Trunk Watermain project will replace and upsize where required 2.4km of various sized large diameter trunk mains between Camden Quay and Shanakiel Reservoir.
The Western Strategic Trunk Watermain project involves the construction of a 5.5km link between the Cork City Water Supply Scheme and the Cork Harbour and City Water Supply Scheme, as supplied from Inniscarra Water Treatment Plant. This watermain will provide additional water supply capacity to Cork City by providing a strategic connection between the water supply schemes and will provide necessary headroom, to facilitate growth and also increase security of supply.
Churchfield Reservoir Roof Replacement - Investing approximately €5 million in the replacement of the existing roof on Churchfield Reservoir. The 40 megalitre reservoir located at Churchfield in Cork city was originally constructed in 1982 and currently supplies drinking water to over 34,000 Uisce Éireann customers. It comprises of a 73m circular reinforced concrete structure in which a maximum depth of 10m of water is stored. The investment will ensure appropriately treated, safe and reliable drinking water is supplied to customers in the area.
Skibbereen Regional Water Supply Scheme Upgrade - Uisce Éireann is investing €28 million on the Skibbereen Regional Water Supply Scheme to benefit over 7,000 people. This project will provide a safe, secure and reliable supply of drinking water. Skibbereen Regional Water Supply Scheme is currently supplied with drinking water from five separate water treatment plants. At present three of these, namely Drimoleague Water Treatment Plant (WTP), Skeagh WTP (near Schull) and Ballinlough WTP (near Leap), are providing inadequate levels of treatment.
Additionally, both Schull high level and Leap supply areas are currently vulnerable to supply outages in the event of a burst on the network or in the event of source or treatment issues at the plants. There is currently no treated water storage on Sherkin Island, so the supply is vulnerable to outages. Furthermore, sections of the existing water supply pipes at Drimoleague, Castledonovan, Schull, Leap and Bluid have reached the end of their expected lifespan and require replacement.
This project involves the upgrade of the existing water treatment plants at Ballyhilty and Lake Cross, the decommissioning of the existing Drimoleague water treatment plant, Skeagh water treatment plant and Ballinlough water treatment plant, the construction of over 35km of new water mains and the construction of new treated water storage reservoirs in Drimoleague, Schull, Leap and Sherkin. Works are due to be completed in 2021.
This significant project will improve the quality of the water being supplied, ensure a reliable water supply to Skibbereen and the surrounding area, safeguard the water supplies for 7,000 people in the Skibbereen area, increase the security of supply across the scheme, facilitate the removal of Drimoleague, Schull and Leap from the EPA's Remedial Action List (RAL) and ensure compliance with current drinking water regulations.
