About Welsh Water

Welsh Water, officially known as Dwr Cmru Welsh Water, is a water service company in Wales. The company provides drinking water and wastewater services to the majority of Wales and some parts of West England. It is headquartered in Nelson, Wales and has been owned by Glas Cymru Limited since 2001.

The company came about after the privatisation of the Welsh Water Authority in 1989. The Authority itself was a result of the 1973 Water Act, a nationwide restructuring of water companies in the United Kingdom. When it was founded, it took over a number of smaller water services public sectors and local authorities, including South West Wales River Authority, Gwent Water Board, and Cardiff County Borough Council. In fact, the company took over approximately 22 public sectors and 11 local authorities.

Today, it is the sixth largest water services company in England and Wales as well as the fourth largest company in Wales. It serves approximately three million customers in 1.4 million homes. The company supplies over 800 million litres of water every day through more than 26,000 kilometres of water mains. It is also considered to be a ‘not-for-profit’ company, with no shareholders and a dedication to reinvesting profits into the company itself.
