A second boil water notice has been issued for parts of Dublin, Kildare and Meath.

It's estimated that this impacts 600,000 people and relates to homes and/or businesses where the water is supplied by the Leixlip Water Treatment Plant. A statement issued by Irish Water this evening reads:

"Due to heavy rain, turbidity (cloudy water due to suspended particles levels) in the source water for the old Leixlip Plant exceeded acceptable levels. "Plant operators reacted quickly before alarms were activated and shut down the old plant to stop this water entering the network. There were no issues at the new plant, where the level of turbidity was managed by the newer technology on site. "It was essential to re-start production at the old plant, which produces 20% of drinking water for Dublin, otherwise significant restrictions and outages would be inevitable. "As Irish Water cannot guarantee the quality the water from the old plant, a Boil Water Notice is now in place."

As per the previous boil water notice issued two weeks ago, the same areas are included - parts of Fingal, areas in Dublin City Council, parts of South Dublin County Council, parts of Kildare and Dunboyne in Meath.

In consultation with the HSE, as a precaution, a Boil Water Notice to protect the health of customers supplied by Leixlip Water Treatment Plant has been put in place for a second time. More details to follow shortly.
