The delivery of multiple benefits on the Llyn Tegid reservoir safety improvements project

When Wales’ largest natural lake, Llyn Tegid, required significant reservoir safety works, the execution of sympathetic yet well-engineering solutions ensured that the scheme could stand the test of time and achieve multiple benefits for future generations. Placing sustainability at its heart, the scheme, delivered in Spring 2023, totalling £7 million, has involved strengthening works to 3 km of embankments to protect the popular tourist town of Bala from extreme weather. Boosting the wellbeing of residents and visitors within the picturesque Snowdonia landscape, works on the high-risk reservoir did not come without unique challenges. From designing for overflowing events and significant mature tree removal, to protecting internationally important habitats and working within the live reservoir basin, to name just a few. The scheme's success has been a testament to building the right team, implementing the right contractual and management controls, and establishing the right culture for compliant and high-quality solutions. Opportunities for carbon reduction and maximising value for money have been taken alongside new works to facilitate possible future expansion of Bala Lake Railway. Involving the community at every stage of this award-winning scheme, the delivery of benefits has been many, and the experiences are ones to live on for all.
