Dwr Cymru Welsh Water

South West WalesStretching from Bridgend to Aberystwyth, our South West Wales catchment area is surrounded by some of Wales’ most well known beaches and coastal areas. It is a diverse geographical area, with densely populated areas, like Swansea, to far more rural areas in Pembrokeshire and Ceredigion. We serve around 1 million customers in this area and its array of coastal areas means that it attracts thousands of tourists every year. In 2016, 22 Blue Flags awarded to beaches and marinas in the area.

We have large water treatment works in Felindre in Morriston, Swansea, Bolton Hill in Haverfordwest, and Bontgoch, north of Aberystwyth – which benefitted from a £9 million upgrade in 2014/2015. 

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

  • £21 million in West Wales around Cardigan, Llandysul and surrounding areas in water quality work to ensure customers continue to receive a first class supply for decades to come.
  • In renewable energy to help us keep our energy costs down and reduces our carbon footprint, including at our Llyn Brianne reservoir in the Towy Valley - our largest hydroelectric scheme, which creates enough energy to power over 5,700 homes.
  • Working with farmers, land managers and partner organisation near the Teifi river area on our WaterSource project, protecting local drinking water sources from grassland herbicides.

We also have a large wastewater network, with works across the area, with major sites in Bridgend, Swansea, Llanelli, Camarthen, Pembroke Dock, Haverfordwest, Aberystwyth, Cardigan and Lampeter.

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

  • £40 million in RainScape to tackle sewer flooding to homes and the environment, caused by too much rain water getting into the sewer network.
  • £12 million in projects around the Swansea Bay area to protect and improve bathing water quality.

We have 201 CSOs with EDM systems in the area, located around the region. Further details can be found in the table below.
