€2bn Water Infrastructure Funding Approved to Unlock 300,000 Homes by 2030

The Government has approved the mechanism to provide a dedicated €2 billion capital investment package for Uisce Éireann, clearing the way for major upgrades to Ireland’s water and wastewater infrastructure aimed at supporting the delivery of 300,000 new homes by 2030.
The funding, announced by the Department of Public Expenditure, Infrastructure, Public Service Reform and Digitalisation, forms part of the revised National Development Plan (NDP) and is intended exclusively to expand water services capacity for housing development. It will be advanced from the Central Fund to Uisce Éireann under Section 37 of the Water Services (No. 2) Act 2013 and drawn down between 2027 and 2030.
The package is split between two targeted programmes. A total of €1.7 billion has been allocated to the Growth Investment Programme, which will fund water and wastewater capacity upgrades across 72 settlements where infrastructure constraints are limiting housing development. A further €300 million has been earmarked for the Small Towns and Villages Growth Programme, supporting wastewater infrastructure in communities with populations below 2,000 to facilitate housing growth in rural and regional Ireland.
The decision represents one of the largest targeted infrastructure interventions for housing delivery and follows repeated warnings from the development sector that inadequate water and wastewater capacity continues to delay planning permissions, prevent commencements and restrict residential construction across large parts of the country.
The announcement also builds on the Government’s wider commitment to invest €12.2 billion in water services infrastructure under the revised National Development Plan to 2030. According to the Department of Housing, more than €12 billion has now been allocated for water services and water quality over the period, with approximately 95% directed to Uisce Éireann.
Minister for Public Expenditure, Infrastructure, Public Service Reform and Digitalisation Jack Chambers said the investment was designed to remove one of the key barriers to housing delivery while maintaining accountability for public expenditure.
He said the funding would expand water and wastewater capacity, helping to unlock housing development across communities nationwide while ensuring strong governance and value for money.
Tánaiste and Minister for Finance Simon Harris described water infrastructure as fundamental to increasing housing supply, saying the dedicated funding would help unlock new homes throughout the country while introducing enhanced accountability for delivery.
Housing Minister James Browne said water infrastructure remained essential if housing targets were to be achieved at the pace and scale required. He said the investment would unlock development sites across cities, towns and rural communities through Uisce Éireann’s accelerated Growth Investment Programme and Small Towns and Villages Growth Programme.
Alongside the funding approval, Government has agreed enhanced governance arrangements. A Memorandum of Understanding will be signed between the Ministers for Finance, Public Expenditure and Housing together with the Uisce Éireann Board and Chief Executive. The agreement will require regular reporting, programme updates and ministerial oversight to ensure the funding is used solely for the approved infrastructure programmes.
The funding cannot be redirected to other purposes without ministerial approval and expenditure will follow an agreed annual drawdown schedule between 2027 and 2030.
For Ireland’s residential development sector, the announcement provides greater certainty that critical enabling infrastructure will receive dedicated funding over the remainder of the decade. However, the pace at which projects move from funding approval to completed network capacity will ultimately determine whether the investment translates into accelerated housing delivery on the ground.
Water and wastewater infrastructure has consistently been identified by homebuilders, local authorities and infrastructure providers as one of the principal constraints preventing housing development in many parts of Ireland. The success of the €2 billion programme will therefore be measured not simply by capital expenditure, but by how quickly additional network capacity unlocks residential sites capable of delivering the Government’s target of 300,000 new homes by the end of the decade.
