Water quality

Printer-friendly version

The aim is to provide you with high quality, safe drinking water. Drinking water is treated to meet the European Communities (Drinking Water) Regulations 2007. These regulations give formal effect in Irish law to the EU Drinking Water Directive of 1988. These regulations establish strict quality standards for any water used for human consumption. They set out the maximum and guideline values for various different physical, bacteriological and chemical contaminants.

The Dublin Region’s drinking water supply is managed from the source in the catchments to the customers’ taps. Water quality testing and monitoring takes place at every stage of the supply system. Samples are taken in the catchments, during and after the treatment process, in the distribution network and at customers' taps.

On occasion it may be necessary to carry out water quality monitoring or repair and maintenance work at your property. This may require our employees to gain access to your property. Unfortunately bogus callers can sometimes call to your property claiming to be from Dublin City Council’s Water Services. Find out how to identify bogus callers .

Water is tested daily at the Water Treatment Plants and the Distribution Network, according to a water quality monitoring plan agreed to by the Environmental Protection Agency (EPA).
