Although falling in abundance in the UK, it is then largely lost as it is evaporates back into the atmosphere and follows natural water-courses back into the sea. The fresh water that is extracted by the utility companies has to be processed at some cost and complexity before it arrives conveniently through our mains at drinking water standard.
