Dwr Cymru Welsh Water

South East WalesTaking some of the more highly populated areas, including the capital city, and stretching up and across the Rhondda, Cynon and Blaenau Gwent Valleys, Cardiff and Newport, our South East region has some of our largest assets. It’s our highest served area with around 1.8 million customers. In 2016, the area received 2 Blue Flags, including Penarth Marina, one of just three marinas in Wales to be awarded this accolade.

We have large water treatment works north of Merthyr Tydfil, at Llwyn Onn and Pontsticill, feeding across and down the valley towards Cardiff.

We’re investing in water projects across the region this year, including:

  • £1.2 million in and around Cwmbran, Newport and Caerleon to improve water quality for years to come; £1 million in Raglan to upgrade existing water mains; and £2.5 million refurbishing the spillway at our Rhymney Bridge reservoir.

The catchment also has the largest served population at our Cardiff wastewater treatment works, which treats wastewater from almost one million people. 

We’re investing in wastewater projects across the region this year, including:

  • £2.9 million in upgrading our wastewater site at St Mellons, which will help to protect the environment.
  • £150,000 to upgrade our wastewater network in Tunnel Terrace, Newport which will help to alleviate blockages and flooding to properties in this area.

We have 29 CSOs with EDM systems in the area, located around the region. Further details can be found in the table below.
