Irish Water switch back to Ballymore

By Brendan Grehan

IRISH WATER has switched the source of the water supply for North Clondalkin and Lucan from the Leixlip water treatment plant back to the Ballymore Eustace water treatment plant.

The two recent boil-water notices for water supplied from the Leixlip water treatment plant adversely affected residents in Lucan and North Clondalkin who received their water supply from the plant.

Supply-demand balance is managed daily

In the aftermath of Storm Emma in March 2018, Irish Water switched the supply of water to parts of Clondalkin and Lucan from Ballymore Eustace to Leixlip water treatment plant on a temporary basis.

Residents in Lucan and North Clondalkin raised concerns about the change of quality in the water and the increase in turbidity.


Turbidity is a measure of the total suspended solids in the water.

On Tuesday, a spokesman for Irish Water confirmed to The Echo that the water supply had been switched back to Ballymore Eustace.

He said: “Following a recent network reconfiguration, areas in South Dublin County Council are currently being supplied from Ballymore Eustace.

The management of the network is under constant review and reconfigurations of the network can be required to sustain supply.”

The spokesman told The Echo that the water supply in the Greater Dublin Area comes from a number of different water treatment plants primarily the Liffey plants at Leixlip Water Treatment Plant (WTP) and Ballymore Eustace WTP.

He added: “The water balance between the two is a function of the supply-demand balance from time to time and is managed on a daily basis.”
