Boil Water notice for 600,000 Dubliners may last another day

by Rachel Darcy

Irish Water have issued a Boil Water Notice for over 600,000 homes across Dublin, after an issue at a water treatment plant in Leixlip.

The notice has been issued for the entire supply originating from the plant as a precautionary measure, following issues with the treatment process at the plant, which may have compromised the disinfection process that makes water safe to drink.

Issues at the plant have now been resolved, but the affected water is still travelling through the system. The Crisis Management Team at Irish Water are expected to meet this morning, with a meeting scheduled with the HSE for 11am to further discuss the notice.

The Boil Water Notice impacts areas in parts of Fingal, areas in Dublin City Council, parts of South Dublin County Council, parts of Kildare and Dunboyne in Meath.

On this morning’s Morning Ireland, Irish Water’s Yvonne Harris said that the issue may not be resolved for up to three days, and the notice could be in place for another 24 hours.

Full details of the notice and impacted areas are are available on water.ie, and individuals are being advised to keep an eye on Irish Water’s social media for updates.


During a Boil Water Notice, water must be boiled for drinking, preparing foods such as salads that will not be cooked before eating, brushing teeth and making ice.

Water can continued to be used without boiling for personal hygiene, such as bathing and flushing toilets, but can not be used in the mouth for brushing teeth or gargling. Precautions must be taken with children when they are being bathed to ensure they don’t ingest water.

Irish Water encourage bringing the water to a ‘vigorous, rolling boil’, and allowing it to cool – water from the hot tap is not safe to drink. Water filters will also not render the water safe to drink.
