The water supply to Broadford on the Isle of Skye had been identified as potentially inadequate to cope with the higher demand peaks of the busy summer season. This project therefore was to increase the raw water yield from Loch Buidhe high in the hills above Boadford both to reduce the risk during drought conditions and also to accommodate growth within the water supply area.
The main construction works included a reinforced concrete dam and intake structure at the headworks at Loch Buidhe and 1.1km of 280mm diameter raw water pipeline from the headworks down to the existing water treatment works.
To overcome the remote location, a 3km long new access route to the headworks was also constructed – essential to transport the necessary materials plant and equipment up to the loch.
Environmental considerations featured prominently throughout the planning, development and execution phases of this project which was carried out in a designated Site of Special Scientific Interest (SSSI) with protected grasslands. Special measures adopted included the use of roadstone of specific alkalinity and colour and routing both the access road and pipeline to following the natural ground features of cliffs and watercourses.
Once the works were completed, the road footprint was reduced which still enabled quad-bike access to meet future operational maintenance requirements.
The headworks construction were sequenced out-with the fish spawning season and material deliveries were routed to avoid areas of the indigenous golden eagle population – and this included coordinating concrete deliveries by helicopter.
The overall project involves the off-site fabrication and installation of a new linkspan structure at Oban Ferry Terminal for client Caledonian Maritime Assets Ltd (CMal).
