Gwydir Reservoirs

Making sure the reservoirs remain safe in the long-term

Progress Update – August 2019

Following the collapse of Dawnus Construction Ltd in March 2019, NRW has now successfully appointed a new contractor, William Hughes Civil Engineering Ltd to complete the reservoir safety works.

Works will resume this month on Llyn Cyfty, Llyn Sarnau and Llyn Goddionduon with the compound at Cyfty South being re-established. There is considerable material to bring to site to complete the strengthening of embankments and complete spillway construction. Contractor’s large vehicles and material deliveries will be travelling through Betws y Coed, with access to NRW forest roads beginning at NRW’s Sawbench car park. Measures are being put in place to minimise disruption whilst upholding the safety of haulers and the public.

The start date for Llyn Tynymynydd is to be confirmed. An inspection is taking place in August to assess whether to proceed the Llyn Tynymynydd works this year and to risk late winter working, or to defer these works until April 2020 start.

Enquiries

The works shall continue to be carefully managed across the sites to minimise disruption to landowners, local people and visitors to the Forest. For all enquiries please contact the NRW Project Manager, Andrew Basford on 0300 065 3846 or email gwydir.reservoirs@cyfoethnaturiolcymru.gov.uk.

We are starting work to make sure that four reservoirs in the Gwydir Forest near Betws y Coed remain safe in the long-term.

The reservoirs are:

This Plan shows the location of the four reservoirs and the works include:-

  • Strengthening embankments
  • Constructing new spillways
  • Improving access to the reservoirs

Here’s an update on our progress – November 2018

This is part of our work to regulate reservoirs under the Reservoirs Act 1975 and is part of a wider programme of reservoir safety work across Wales.

The Gwydir reservoirs are regularly inspected to make sure they remain safe. At the last inspection, some points were raised over the adequacy of the reservoirs to withstand extreme events.

Whilst there are no immediate concerns, we are looking at ways of ensuring the long-term integrity of the structures.

Work will be phased across the sites to minimise disruption to landowners, local people and recreational users of the forest.

We are fully aware of the environmentally sensitive nature of the areas and all works will be undertaken in a way that is sympathetic to and, where possible, enhances the natural environment.

We will provide regular updates on the work on this website.
