Revealed: Preferred route for €950m Shannon pipeline

Irish Water has unveiled the final route of a €950m water pipeline from the River Shannon to Dublin.

The Eastern and Midlands Water Supply Project includes construction of the country's biggest water treatment plant capable of treating 330 million litres of water a day, and some 500 landowners will be affected by the massive project.

The scheme involves abstracting 4,000 litres of water a second from the eastern side of Parteen Basin on the lower Shannon, before it is processed in the country's largest water treatment plant 3km inland.

From there, the water will be pumped over 40km to a 'break pressure' point near Cloughjordan in Tipperary, before falling by gravity to Dublin and a new 150 million litre-capacity reservoir at Peamount.

A desalination plant in north Dublin was ruled out because it would cost 40pc more, and would not serve the midlands. Land costs are expected to make up around 50pc of the project budget.

The need for a new supply for Dublin was first acknowledged in 2000, but it has since been expanded to allow for growth in the midlands. Water can be drawn from the pipeline in Tipperary, Offaly and Kildare to cater for regional growth.

Less than 2pc of the River Shannon's flow will be abstracted, and the project will be completed in 2025.

The utility expects to reach agreement with around 80pc of affected landowners, but will acquire land under compulsory purchase orders if necessary.
