Since 1 January 2014, Irish Water has statutory responsibility for all aspects of water services planning, delivery and operation at national, regional and local levels. Issues in relation to the costs of the project referred to in the question and the allocation of funding towards the project are matter for Irish Water.
As part of Budget 2021, I secured funding of over €1.4 billion to support water services. This includes €1.3 billion in respect of domestic water services provision by Irish Water. This overall investment will deliver significant improvements in our public water and wastewater services, support improved water supplies right across Ireland, including rural Ireland, and support a range of programmes delivering improved water quality in our rivers, lakes and marine area. The prioritisation and progression of individual projects is a matter for determination by Irish Water.
Irish Water has established a dedicated team to deal with representations and queries from public representatives. The team can be contacted via email to firstname.lastname@example.org or by telephone on a dedicated number, 1890 578 578.
