Welsh Water recently welcomed Delyn Member of the Senedd, Hannah Blythyn and North Wales Regional Member, Carolyn Thomas to their site at Cilcain to see how the company is restoring part of the natural landscape in the area.

Work is underway in Cilcain by Welsh Water to return two of the four local reservoirs back to their natural state as part of the Nant Gain River.
Situated just outside Cilcain village in the eastern foothills of the Clwydians, the four reservoirs were originally constructed in the late 19th century to supply drinking water for the local area. However, they are no longer a part of the drinking water network, with customers now being supplied from the Alwen reservoir.
The restoration process involves removing the dam structures at Cilcain 1 and 2 reservoirs, enabling the construction of a new channel. The new channel will allow the river to flow along its natural course, replicating how it would have been before the dams were built. Work being carried out by the not-for-profit water company started on site in March and should be finished by the end of the year.
Tudur Ellis, Welsh Water’s Project Manager for the scheme said:
“With changes to reservoir safety legislation, keeping the reservoirs as they were was not an option as they required significant investment and construction work to bring them up to current regulations, this is why Welsh Water is returning the natural landscape.
"By carefully designing the restoration process, we aim to enhance the biodiversity in the area by reinstating the natural river corridor, creating a thriving habitat for wildlife. The reservoirs are located within an Area of Outstanding Natural Beauty near Moel Famau, and restoring the site to its natural state is in keeping with the surrounding landscape."
The investment of over £2 million in Cilcain by Welsh Water follows a further £3 million investment to return Llyn Brân in Denbighshire and Llyn Anafon in Gwynedd to natural lakes.
When the new river corridor has been completed, the area surrounding the river will be left for nature to carry out its work and in a few years’ time the surrounding landscape should flourish and return back to its natural green terrain.
