An estimated 350 million litres of water would be taken from the river each day before being treated in Birdhill and piped 170 kilometres to the capital.

The Water Supply Project Eastern and Midlands Region is the biggest project ever undertaken by Uisce Éireann.

Tipperary TD Mattie McGrath is encouraging people to have their say whether they are in favour or opposed to the multi-billion Euro scheme.

He has been critical of Uisce Éireann for their failure to tackle huge leakage issues in Dublin.

It’s estimated 45% of the water in the capital is being lost from the network.

Submissions to An Coimisiún Pleanala on the project close this afternoon at 4.30.
