Pettigo in county Donegal is one of 43 water supplies around the country now under nighttime restrictions.
The restrictions were put in place last night meaning the water pressure was reduced over night from 11pm until 7am.
Irish Water says these restrictions will remain in place for the foreseeable future and along with Donegal County Council they will be monitoring the supply carefully.
The Lough Mourne and Inishowen supplies are still deemed at risk.
