I wish a good morning to all the members of the committee. I thank the Cathaoirleach for the invitation to attend today's meeting. I am Niall Gleeson, CEO, and the Cathaoirleach has already introduced my other colleagues.
We welcome the opportunity to appear here today in what will be our first appearance before the committee as part of the Comptroller and Auditor General process, and to discuss our financial statements for 2023. These statements for 2023, as part of our annual report for last year, were laid before the Houses of the Oireachtas prior to the summer recess by the Minister for Housing, Local Government and Heritage and were also published on our website. We have also made a submission to the committee summarising the report for members' interest, including Uisce Éireann's role, the governance structure and financial performance highlights from last year. We look forward to discussing this in more detail during this morning's session and we note the special areas of interest highlighted to us by the committee on Tuesday evening.
Uisce Éireann is responsible for the delivery of secure, safe and sustainable public water services enabling the Irish economy to grow and communities across Ireland to thrive. On a daily basis our national team of some 4,000 people are directly involved in delivering essential water services to 80% of Ireland's population, and supporting the drive for connections in order to provide more homes and to enhance Ireland's economy.
We are currently investing €5.26 billion in water service assets across the country, as part of our strategic plans for 2020 to 2024. With this investment we are managing, maintaining, upgrading and building on more than 8,000 water and wastewater treatment plants, pumping stations and water sources. Through our projects, programmes and daily operations, we are upgrading, laying and managing a water and sewer network of 90,000 km. We provide a robust governance and risk management across the organisation with multiple layers of accountability and oversight.
Uisce Éireann was established under the Water Services Act 2013. We are a State-owned entity. As such, we uphold a strong transparent governance framework to ensure accountability, value for money and responsible investment as regards Exchequer funding.
Uisce Éireann complies with the provisions of the code of practice for the governance of State bodies as it applies to a commercial semi-State entity. We align our internal project approvals process with the public spending code and we adhere to the infrastructure guidelines set up in the national development plan.
We are governed by a board that meets monthly and is assisted by four subcommittees covering: audit and risk; investment-infrastructure and sustainability; remuneration; and the Uisce Éireann transformation programme. These committees meet, on average, seven times a year. In addition, we report to our two regulators, namely, the Commission for Regulation of Utilities, CRU, and the Environmental Protection Agency, EPA. They review and publish their assessments on a range of economic and environmental performance indicators.
Our funding framework is complex but we are delivering one of the biggest capital investment programmes in the country. The funding and regulatory model for Uisce Éireann is set out in legislation and positioned in the context of the overarching EU water framework directive. As part of this, we are required to submit plans in advance to the Commission for Regulation of Utilities for our proposed operational and investment spending in revenue funding cycles. We are currently in the third of these funding cycles and are preparing our submission to the CRU for the revenue period covering 2025 to 2029. This five-year allowance should enable Uisce Éireann and our supply chain to have the certainty, flexibility and time to be able to plan and deliver high-value, multi-annual projects and operations. However, actual subvention income and equity are currently subject to the Government’s annual budgetary process, which can impact on the long-term certainty around our projects. We have consistently advocated for a move towards multi-annual funding.
Uisce Éireann delivered a strong financial performance during 2023. We delivered the highest level of investment in water and wastewater services in our history, and the history of the State, totalling €1.3 billion in 2023, compared with just over €1 billion in 2020. Key milestones in the year included the construction of 42 new and upgraded wastewater treatment plants, nine water treatment plants, 122 km of sewers and 512 km of water network.
Vital projects were delivered, including under our programme to eliminate raw sewage discharges. Kilmore Quay, County Wexford, Ahascragh, County Galway, and Castletownshend, County Cork, were among a total of ten sites completed in the programme last year.
We also remain committed to playing our part supporting housing delivery and our work under the Government's Housing for All programme continued in 2023. Uisce Éireann completed all five of the key action items assigned to it in the programme. These included the development of an experience-based accreditation scheme, the publication of capacity registers and the implementation of our first mover scheme. We also witnessed continued demand for new connection inquiries and application services. We delivered over 4,500 connection offers associated with almost 43,000 housing units in 2023. The housing units associated with these offers was up over 16% on the previous year. These and other capital investment activities continue to be a significant source of economic stimulus, in addition to our operating and maintenance programmes, which continue to provide both direct and indirect employment and other economic benefits across the Irish economy. We work with over 2,000 Irish and international businesses and suppliers to deliver our work.
Revenue of €1.56 billion for the year to 31 December 2023 was €252 million higher compared with 2022. This was made up of Government subvention income of circa €1.07 billion in respect of domestic water services, as well as non-domestic and new connection revenues of €492 million. Operating costs of €1 billion increased by €115 million when compared with 2022. This is due to a number of factors including: the delivery of significant operational growth and change in 2023 across our direct operations, coupled with the continuing impact of inflation and increased headcount to right-size the organisation for a new operating model, which brings in the responsibility for water and wastewater services for the nation.
We are continuing to make improvements as a maturing semi-State body undergoing significant transformation. In the ten years since our establishment, we have made significant progress, building on the foundations created by local authorities' legacy of vocational delivery of services to customers and communities. We have mobilised a large, strategic workforce and supply chain to support the delivery of plans and programmes and to catch up on decades of underinvestment. The public, businesses and the environment are seeing the benefits of this already. There is still a way to go, however, to ensure capacity is available for continued housing and economic growth and to mitigate against environmental risks. Our water services strategic plan 2050, the national water resources plan and the upcoming capital investment plan for 2025 to 2029 all set out our approach to achieving these improvements.
In the context of ongoing public discussion about long-standing infrastructure challenges, the potential for water and wastewater infrastructure to be prioritised in leveraging strategic national funding sources will be essential. It will provide the basis to accelerate projects that are central to Ireland’s economic and social development. This includes providing the water infrastructure to meet current and future levels of demand for housing provision in parts of the country where the need has been identified, by county development plans, as being the greatest.
Over the next period, Uisce Éireann will continue to navigate the transfer of local authority water services staff, incoming European regulation and increased population and economic demands. We do not underestimate these challenges. While we will see increased pressures on resourcing, timelines and funding in the immediate term, in the long term and through our investment plans we will continue to make up ground, achieve the vision of one national public utility for water and deliver for the people, businesses and communities of Ireland.
To conclude, I thank the committee for the invitation to meet today and we look forward to answering any questions. We will endeavour to provide information on the topic under debate today but commit to following up on any specific queries that we cannot answer or that may fall outside the scope of the session this morning. Go raibh maith agaibh.
