Uisce Éireann (Irish Water)

The Water Services (No. 2) Act 2013 established Irish Water (Uisce Éireann) as a subsidiary of Bord Gáis Éireann, with a mandate to take over responsibility for public water and wastewater services from 34 local authorities. The Act provided for the introduction of domestic water charges and the metering of all households. The transfer of functions from local authorities to Irish Water was to be phased in. Then-Minister for the Environment Phil Hogan was the responsible minister.

Irish Water began billing domestic households for water services from October 2014 under a metered charging regime. Charges were €176 per year for a single adult household and €278 per year for multi-adult households in the first phase, with free allowances for children. This was the first time since 1997 that Irish households faced a direct charge for domestic water supply. The introduction of charges, combined with controversy over Irish Water's governance costs, bonus payments to employees, and PPS number collection, triggered a major public backlash.

On 11 October 2014, an estimated 100,000 people marched in Dublin against the introduction of domestic water charges, with simultaneous protests in Cork, Galway, Limerick and other cities bringing the national total to an estimated 150,000. The protests, organised by the Right2Water coalition (which included trade unions SIPTU, Mandate, CWU and Unite, alongside political parties Sinn Féin and People Before Profit), were among the largest street demonstrations in the history of the State. Further protests on 1 November 2014 drew comparable crowds. Public opposition to water charges became a significant factor in the 2016 general election.

Following the 2016 general election, in which no party won an overall majority and opposition to water charges was a dominant issue, the minority Fine Gael government (supported by Fianna Fáil) agreed to suspend water charges pending the report of an independent expert commission. The Water Services (Amendment) Act 2016 provided for the suspension of charges and the refund of monies already paid. A cross-party Oireachtas committee and the Kieran Mulvey Expert Commission were established to examine the future funding model.

The Water Services Act 2017 formally abolished domestic water charges for households, following the recommendation of the Mulvey Expert Commission. The Act retained an Excessive Usage Charge (EUC) for households using above a specified free allowance (currently 213,000 litres per year for a household). Ireland became one of very few EU member states that does not charge households for domestic water at the point of use. The Act also provided for full refunds to households that had paid charges. Total refunds paid exceeded €170m.

From 2018, Irish Water was progressively restructured and separated from the Ervia group (formerly Bord Gáis Éireann). Governance reforms were introduced in response to criticism of management costs, bonus payments and oversight failures identified in Dáil committee hearings. The Commission for Regulation of Utilities (CRU) was given an enhanced regulatory role over Irish Water's capital programme and pricing. The transformation to Uisce Éireann branding was completed in 2022 when the utility was fully separated from Ervia.

Uisce Éireann launched its national lead remediation programme in 2019, targeting lead water mains and service connection pipes in older urban areas (principally pre-1970s housing stock in Dublin, Cork and other cities). Lead pipes cause elevated lead concentrations in drinking water, posing particular risks to children's neurological development. The programme committed to replacing lead-containing distribution mains and subsidising householder replacement of internal lead plumbing. The EPA set a target for elimination of lead in drinking water in line with the revised EU Drinking Water Directive (2020/2184).

The EPA published its Urban Wastewater Treatment Report for 2022, documenting that a significant number of urban wastewater treatment plants operated by Uisce Éireann were non-compliant with the Urban Waste Water Treatment Directive (91/271/EEC). Areas with persistent non-compliance included Killarney, Wexford, Athlone and several others, with untreated or partially treated sewage being discharged to rivers and coastal waters. Ireland had been the subject of a European Commission infringement action in respect of Urban Wastewater Directive compliance. The EPA placed Uisce Éireann on its Priority Action List.

The National Development Plan 2021–2030, published in October 2021, committed €13bn in capital investment over the decade to water supply, water quality and wastewater treatment infrastructure managed by Uisce Éireann. This represented the largest ever single-decade capital allocation to Irish water infrastructure. The investment programme included new water treatment plants, wastewater treatment upgrades, network rehabilitation, lead remediation and drought-resilience infrastructure. The CRU oversees Uisce Éireann's multi-annual revenue determination to fund capital expenditure.

Uisce Éireann reported in 2024 that the number of boil water notices affecting significant populations had declined compared with the peak years of 2019–2020, reflecting capital investment in water treatment plant upgrades. However, smaller supplies in rural areas continued to carry quality advisories. The EPA's drinking water report for 2023 noted overall compliance rates above 99.9% for treated water supplies serving the majority of the population, while identifying ongoing challenges for smaller private group water schemes.

As of May 2026, Uisce Éireann is delivering its NDP 2021–2030 capital programme under CRU regulatory oversight. The revised EU Drinking Water Directive (2020/2184/EU), which must be transposed into Irish law, sets a stricter standard for lead in drinking water (5 μg/L by 2036, tightened from 10 μg/L). Uisce Éireann's lead remediation programme is ongoing. EPA enforcement actions in respect of Urban Wastewater Directive compliance continue, with a number of plants under formal enforcement notices. Ireland's wastewater compliance has been the subject of ongoing European Commission monitoring.

The €13bn NDP capital programme has funded significant upgrades to water treatment plants, reducing the number of boil water notices and improving compliance rates for treated water. The EPA's drinking water report for 2023 recorded compliance above 99.9% for large supplies. However, EPA Urban Wastewater Treatment reports have documented persistent non-compliance with the Urban Waste Water Treatment Directive at multiple plants, with untreated and partially treated wastewater discharges to rivers and coastal waters. Ireland remains under European Commission scrutiny for urban wastewater compliance.

Lead water pipes remain in older housing stock in Dublin, Cork and other pre-1970s urban areas, posing a risk of elevated lead concentrations in drinking water. Lead exposure at any level is harmful to children's neurological development. The EU Drinking Water Directive (2020/2184/EU) requires Ireland to reduce the lead standard in drinking water from 10 μg/L to 5 μg/L by 2036. Uisce Éireann's national lead remediation programme is replacing lead distribution mains and subsidising replacement of internal lead plumbing, but full replacement of all lead-containing infrastructure will take decades.

The National Development Plan 2021–2030 committed €13bn in capital expenditure to Uisce Éireann's water and wastewater infrastructure programme. This represents one of the single largest infrastructure investment programmes in Irish State history. Funding is sourced from a combination of general taxation (as domestic water charges have been abolished), EU structural funds, and regulated capital allowances via the Commission for Regulation of Utilities. The scale of the programme reflects decades of underinvestment in water infrastructure by local authorities prior to the establishment of Uisce Éireann.

Multiple urban wastewater treatment plants in Ireland continue to discharge untreated or inadequately treated sewage to rivers, lakes and coastal waters, in breach of the Urban Waste Water Treatment Directive (Council Directive 91/271/EEC). The EPA's enforcement action against Uisce Éireann includes formal enforcement notices and Priority Action List designation. Ecological damage to receiving water bodies — including nutrient loading, algal blooms and dissolved oxygen depletion — has been documented by the EPA's water status assessments. Ireland's failure to achieve Water Framework Directive (2000/60/EC) water body status targets is partly attributable to urban wastewater discharges.

Directive 91/271/EEC requires member states to ensure that urban wastewater entering collecting systems receives secondary treatment (biological treatment) before discharge to receiving waters, and more stringent treatment where waters are sensitive. Ireland must ensure all agglomerations above 2,000 population equivalent have compliant collecting systems and treatment plants. The European Commission has taken infringement action against Ireland in respect of multiple persistently non-compliant agglomerations.

If breached: European Commission infringement proceedings; CJEU referral and potential financial penalties; continuing ecological damage to receiving waters.

The Water Framework Directive requires member states to achieve 'good status' for all surface water and groundwater bodies by 2027 (extended from original 2015 deadline). Ireland's River Basin Management Plans — the primary implementation tool — are produced by the Department of Housing, Local Government and Heritage. Uisce Éireann's wastewater discharges are a significant factor in Ireland's failure to achieve the required 'good ecological status' for many river and lake water bodies. Ireland submitted its third River Basin Management Plan for 2022–2027.

If breached: European Commission infringement proceedings; CJEU referral; failure to achieve WFD environmental objectives.

The recast EU Drinking Water Directive (2020/2184) sets new and stricter standards for drinking water quality, including a reduction of the permissible lead concentration from 10 μg/L to 5 μg/L by 2036, new parameters for endocrine disruptors and microplastics, and access-to-water obligations. Ireland was required to transpose the Directive by January 2023. Uisce Éireann's lead remediation programme and drinking water monitoring regime must be aligned with the new standards.

If breached: European Commission infringement proceedings; failure to meet new lead standard exposes Irish consumers to elevated lead risk.

The Right2Water coalition argued that water should be a public good and a human right, and that charging households for domestic water supply was a double-tax on citizens who already paid for water through general taxation. The coalition pointed to Article 28 of the Irish Constitution and to the EU's recognition of the human right to water. The scale of public protest — estimated 150,000 nationally on 1 November 2014 — was cited as evidence of democratic opposition to the charges. The objections were ultimately accommodated by the suspension and abolition of charges in 2016–2017.

Oireachtas Public Accounts Committee hearings in 2014–2015 documented controversies over Irish Water's governance costs, including the cost of an external consultant contract to collect PPS numbers from customers (the 'PR strategy' controversy), bonus payments to Irish Water management at a time of austerity, and the overhead costs of establishing a new national utility. Opposition TDs argued that Irish Water's establishment had been poorly managed and that the governance structure — as a subsidiary of a commercial State company — was inappropriate for what should be a purely public utility.

Environmental NGOs and community groups in areas affected by wastewater discharges (including Lough Derg, River Erne and coastal areas in Wexford and Waterford) raised objections that Uisce Éireann's progress on wastewater compliance was insufficient given the scale of the NDP capital programme. The objection was that prioritisation of new water supply infrastructure had come at the expense of wastewater treatment upgrades, and that the resulting ecological damage to river and lake water bodies was incompatible with Ireland's Water Framework Directive and Urban Wastewater Directive obligations.
