What does Welsh Water do?
Welsh Water, or Dŵr Cymru, provides water supply and sewerage services to most of Wales and parts of neighbouring England. It earns money from customer bills, with prices and investment set by the regulator Ofwat. Unusually, it is owned by Glas Cymru, a company limited by guarantee with no shareholders, so any surplus is kept in the business for customers.
