• £9 million investment to refurbish the spillway at Lluest Wen Reservoir.
  • Buffy Williams visited the site and thanks Dŵr Cymru for the investment at the reservoir in Maerdy.

Dŵr Cymru Welsh Water are investing £9 million to upgrade the assets at Lluest Wen Reservoir. This investment will help ensure around 15,000 customers across the Rhondda Fach and in surrounding areas continue to receive a top-quality drinking water supply.

The work being carried out by the not-for-profit company involves refurbishing the spillway, which is the overflow for the reservoir. This feature allows excess water from the river which is not used for drinking water supplies to pass safely around the dam. Keeping this asset in good condition is essential as it helps protect the dam against flood damage and ensuring a reliable source of water for the whole community.

Work began in October 2020 and is making great progress. The concrete bases that form the spillway are on track to be completed this month and work is underway to construct the walls and drainage system. The work is currently on track to complete during Spring 2022. While work is being carried out, there will be no impact on water supply to local customers.

Welsh Water invited Buffy Williams, Member of the Senedd for the Rhondda, to site to show her first hand the investment work being carried out to keep the company’s assets in good condition and customers in supply of fresh drinking water.

Following the visit, Buffy said: “”Earlier this year I was fortunate enough to visit Lluest Wen Reservoir to view the progress made by Dŵr Cymru on the new spillway. We’ve received stark reminders in recent times that the defences put in place before climate change are not going to be good enough for the future.  

“I can’t thank Dŵr Cymru enough for the £9 million of investment at the reservoir in Maerdy which won’t only bolster our defence against more severe weather, but provide a safe supply of water for our communities too.” 

Rhys Hellin, Welsh Water Sub Programme Manager, said: “Our £9 million investment is essential to ensure we continue to provide customers in the area with a first-class drinking water supply.  As a not-for-profit company we continue to invest in our assets to strengthen our resilience and continue to improve the service to our customers.    

“While we don’t expect this work to cause any disruption to local customers, they may notice an increase in traffic and deliveries to the site via an access road off the A4061.  Please be assured that this will not have any impact on any local residential areas and as our work progresses, we will continue to publish any updates through the In Your Area section of our website.” 

The work forms part of the £1.8 billion investment being made by the not-for-profit company between 2020 and 2025 to improve services to customers and protect the environment.  For more information visit www.dwrcymru.com/Lluest-Wen
