Dyr Cymru Welsh Water

Parent company:         Glas Cymru

Regulated utility:         Dwr Cymru Welsh Water Ltd

Ownership:                   Not for profit organisation

Welsh Water's parent company Glas Cymru is an unusual water company, its the only not for profit organisation in the water industry. This means it has no shareholders and profits are either reinvested in the business or returned to customers.

Welsh Water's sole purpose is to acheive the highest standards possible at the lowest cost. They are able to take this singleminded approach as they have no shareholders and after paying interest on loan capital can reinvest surpluses in the business. The result is that they have reduced bills for customers for 10 consecutive years.

Welsh Water is unique among the water companies in having copious supplies of raw water due to its geography and high rainfall in Wales. Hence water leakage is of low concern but waste water treatment and in particular coastal discharges, are an important issue. Welsh Water has successfully reduced customer's water bills with its unique annual customer dividend.

Like other water companies it is seeking to keep bill increases down (1% below the rate of inflation) for AMP6 (2015-2020) while investing 1.5bn.
