Boil Water Notice

On Tuesday evening a Boil Water Notice was issued for those served by the Leixlip Water Treatment Plant. The Boil Water Notice was issued as a precautionary measure following issues with the treatment process at the Water Treatment Plant which may have compromised the disinfection process which makes the water safe to drink. According to Irish Water, the issue is now resolved but the boil water notice will remain in place until they can confidently demonstrate to the HSE that the water is safe to drink.

Who is affected?

This Boil Water Notice impacts approximately 600,000 people supplied by the Leixlip Water Treatment Plant. The areas impacted are as follows; parts of Fingal, most of north Dublin, parts of South Dublin County Council, parts of Kildare and Dunboyne in Meath.

How did this happen?

There were issues with the treatment process at the Water Treatment Plant which may have compromised the disinfection process which makes the water safe to drink. Irish Water are working with partners in Fingal County Council who run the plant to investigate the cause. The issues have now been resolved, but the water is travelling through the system which is why the Boil Water Notice is being out in place.

Why is the boil water notice in place if the situation is resolved?

The partially treated water is still in the network and could pose a risk so the boil water notice is in place until the HSE is satisfied that the water is completely safe to drink.

How long will the Boil Water Notice remain in place?

Irish Water will continue to test the water and the Boil Water Notice will be in place until the HSE advise that it can be lifted. Irish Water will continue to update our customers on water.ie and via their social media channels.

What happens next?

The Crisis Management Team will meet first thing this morning and Irish Water will meet the HSE at 11am. Water will continue to be tested during the day.

The Irish Water website went down and people couldn’t get information?

Unfortunately due to the volumes accessing the Irish Water website experienced some difficulties. In the interim, Irish Water have posted a link on their Twitter channel @IWCare where customers can enter view the affected areas. Information and the map of the affected areas were on twitter and Facebook, then Irish Water immediately started to call vulnerable customers, large water users, and through the HSE nursing homes and other facilities.
