Householders in Dublin are being advised to conserve water as they are likely to lose water supply in the coming nights.
The four local authorities in the capital are imposing nightly restrictions from 8pm tomorrow night in an attempt to restore levels.
It follows a serious production problem at the Ballymore Eustace Water Treatment Plant.
The restrictions, which run until 7am, are likely to remain in place until at least next Monday - and will be reviewed on a daily basis.
