Water Supply Project Eastern and Midlands Region
This project has capacity to address supply water needs for up to 50% of the State’s population.
Project overview
Our purpose is to deliver transformative water services that enable communities to thrive. For the Eastern and Midlands Region, rising to this challenge requires a new water source.
Today, we have just one source to supply 85% of the water for the Greater Dublin Area – the River Liffey. This dependence on the Liffey (and the two main treatment plants of Ballymore Eustace and Leixlip) results in a serious vulnerability to risks such as prolonged drought and/or contamination. Furthermore, economic growth, population growth including the demand for housing and the impact of climate change means our forecasts show that the region will need 34% more water by 2044 than is available today. This combination of a growing water supply deficit and lack of supply resilience is not sustainable-we need a new source of water.
The solution is the Water Supply Project Eastern and Midlands Region. A critical national infrastructure project, it will have capacity to support water supply needs for up to 50% of our population. It will bring treated water from the Parteen Basin to Peamount in Dublin with the capacity for offtakes along the route in Tipperary, Offaly and Westmeath. It will also enable supplies serving Dublin to be redirected back locally in Carlow, Wicklow, Meath and Louth.

The Project
The proposed Water Supply Project Eastern and Midlands Region will abstract a maximum of 2% of the average flow of the River Shannon at Parteen Basin. The project is in line with the National Water Resources Plan (Framework Plan) and the Regional Water Resources Plan for the Eastern and Midlands Region. The Project will;
- Abstraction of water from the lower River Shannon at Parteen Basin in Co. Tipperary, downstream of Lough Derg
- Treatment of the abstracted water at Birdhill, Co. Tipperary
- Pipe the treated water 170km through Tipperary, Offaly and Kildare to a termination point reservoir at Peamount in County Dublin
- Connect into the Greater Dublin Area water supply network, with capacity to provide water to communities along the route.
