  In the United Kingdom regulation of water supplies is a devolved matter to the Welsh and Scottish Parliaments and the Northern Ireland Assembly.
  
  In England and Wales there are two water industry regulatory authorities.
  
  The functions and duties of the bodies are formally defined in the Water Industry Act 1991 (1991 c. 56) as amended by the Water Act 2003 (2003 c. 37) and the Water Act 2014 (2014 c. 21).
  
  In Scotland water quality is the responsibility of independent Drinking Water Quality Regulator (DWQR).
  
  In Northern Ireland the Drinking Water Inspectorate (DWI) regulates drinking water quality of public and private supplies. The current standards of water quality are defined in the Water Supply (Water Quality) Regulations (Northern Ireland) 2017.
