European Communities (Quality of Water Intended for Human Consumption) (Amendment) Regulations, 2003 (S.I. No. 259 of 2003).

The Regulations place a duty on those responsible for certain private water supplies, i.e. a water supply intended for human consumption which is not in the charge or ownership of a sanitary authority or any person acting on its behalf, to take the necessary measures to ensure that drinking water supplied meets the prescribed standards. The Regulations also provide for procedures and remedial actions to be taken where supplies do not meet the standards.
