Problems with your water supply

Printer-friendly version

On a typical day 540 million litres of water is collected from our rivers, cleaned and made safe to drink at four main treatment plants in the Dublin Region at Ballymore Eustace (River Liffey), Roundwood (River Vartry), Ballyboden (River Dodder) and Leixlip (River Liffey).

Occasionally, however, drinking water is not up to standard and this can be for a variety of reasons.

When you examine your drinking water, it should appear clear and bright and it should be of consistent pressure.

If it is discoloured, cloudy or has an unwanted taste or smell, or if you have experienced a loss of supply or poor pressure you should contact us immediately at the details below.

Some problems with the water supply may be the responsibility of Irish Water and some may be the responsibility of the Customer. See below for more details:

The following problems may be encountered occasionally by our customers. The links below are intended to provide information only on what the possible causes of any potential problems you may encounter with your drinking water:
