£9 million investment boost to drinking water network

Alwen water treatment works has been officially opened following work to upgrade and improve the existing site – ensuring high-quality drinking water for people in north-east Wales for decades to come.

The £9 million investment by Welsh Water at their Alwen site near Cerrigydrudion which supplies drinking water to homes and businesses in Denbighshire and Flintshire, will ensure customers continue to receive water of the highest quality.

The not-for-profit company made the investment as part of a £120 million upgrade plan, with the improved Alwen site officially opened by Clwyd West Assembly Member Darren Millar. 

The investment has been carried out to ensure more stringent water quality standards are met and was part of an upgrade to 12 water treatment works across Wales.

The improvements to the Alwen water treatment works included upgrading the water treatment process through the introduction of state of the art equipment and technology.

Following the official opening, which was held at the company’s nearby Brenig Visitor Centre, guests were then chance to see first-hand how the works had been upgraded during a guided tour of the works. 

Darren said:

“It was a pleasure to be part of the event today to mark the completion of this significant investment at Alwen water treatment works.

“It is important for people to have access to a drinking water supply that they have confidence in and the investment here by Welsh Water will no doubt go a long way to achieving this for decades to come.”

Ian Christie, Welsh Water’s Managing Director of Water Services, said:

“We’re delighted to have completed this significant investment scheme here at Alwen which will further improve the quality of a product which plays such an important role in the lives of our customers. Providing customers with a safe and reliable drinking water supply is and always will be one of our main priorities.

“As the existing Alwen water treatment works was located on a constrained site, the new equipment and buildings had to fit in and around an already congested area which at times proved challenging, however the investment was carried out without any impact on service to customers. Another key challenge of working in a very remote location like Alwen was building in extreme weather conditions which included extended cold periods and heavy snow. This meant getting equipment and people to site on some occasions was very challenging.”

Other sites that have received improvements as part of the £120 million upgrade plans include Alaw and Cefni on Anglesey, Bala, Garreglwyd near Llan Ffestiniog and Dolbenmaen in Gwynedd,  Capel Curig, Llyn Conwy in Conwy, Elan and Llyswen in Powys, Bont-goch in Ceredigion, and Bryngwyn, Carmarthenshire.

The company is investing a record £1.7 billion in its water and wastewater network between 2015 and 2020.
