The Water Supply (Water Quality) Regulations 2018
These Regulations supplement Chapter III (Water Supply) of the Water Industry Act 1991 (“the 1991 Act”) and revoke and replace the Water Supply (Water Quality) Regulations 2010. They are primarily concerned with the quality of water supplied by water undertakers whose areas are wholly or mainly in Wales (and water supply licensees using the supply systems of such undertakers) for drinking, washing, cooking and food preparation, and for food production, and with arrangements for the publication of information about water quality.
