Dee Valley Water

Dee Valley Water supplies water services to an area of 831 square kilometres in North East Wales and North West England.

Dee Valley Water was formed when Chester Water Company and Wrexham Water Company merged in 1997.

Dee Valley Water derives its water from eight impounding reservoirs, two abstractions from the River Dee and two underground sources. As a result Dee Valley Water supplies approximately 70 million litres per day to over 257,000 customers, via seven treatment works, 1,970km of water mains, 25 pumping stations and 37 clean water storage reservoirs.

Dee Valley Water is a water only supplier, so Dee Valley Water customers will have their sewerage services supplied by United Utilities Water or Dwr Cymru (Welsh Water) (Welsh Water), depending on where they live in the water supply region. As two separate companies provide water and sewerage services, Dee Valley Water customers may receive separate bills for each service or Dee Valley Water may bill them for both services and collect the money on behalf of the sewerage company.

Dee Valley Water is generally a hard water area. However, water hardness levels can vary within each area. Dee Valley Water can provide you with further information about water hardness in your particular area.

Dee Valley Water operates a Code of Practice that sets out the levels of service domestic Dee Valley Water customers can expect, such as query response times. If Dee Valley Water fails to meet those levels then customers will be credited with £10.
