Irish Water and Ervia both have their headquarters on the corner of Talbot St and James Joyce St, Dublin 1.
This week, businesses in Liberty Corner, on the other side of James Joyce St, were issued with boil water notices by officials from Dublin City Council.
It is unclear whether the issue affected the large amount of residential units on the street.
A spokeswoman for Irish Water said they were unaware of the notices being issued, despite Dublin City Council confirming the notices. The Irish Water building was not affected.
Dublin City Council confirmed they had been testing water samples from the street this week, but said the water is now safe.
“Dublin City Council received a request for water samples to be taken in that area,” the council said in a statement.
“Samples were taken and the results indicate the water is fully compliant with Drinking Water Regulations 2014 and is safe for human consumption.”
Although the water appears to have been deemed drinkable last night, some businesses in the area had not yet been informed. The Dublin Buddhist Centre and Dublin City Council’s Lab Incubation space said they were still operating under boil water notices last night.
