Uisce Éireann Project Stages
The Infrastructure Guidelines, published in December 2023, sets out the value for money guidelines for the evaluation, planning and management of public investment projects, including purchase or acquisitions of assets or shareholdings. As a body in receipt of public funding, we must comply, as appropriate, with the relevant requirements of the Infrastructure Guidelines.
The Infrastructure Guidelines has a multi-stage approvals process to facilitate the delivery of a capital project and we align our internal approvals process to these project lifecycle stages. The project stages must be adhered to and are subject to procurement, planning, legal and environmental regulations.
