The project involved improving the water supply-demand balance during drought conditions in the Tarbert water supply area of Harris on the Western Isles through the construction of a raised impounding dam at Loch Braigh along with associated pipework, level monitoring equipment, fish pass and access road.
The main construction elements included:
Due to the remote nature of the works and existing steep unstable access track, it was imperative to establish permanent safe access both to undertake the construction works and to provide a permanent safe access route for future maintenance operations.
For the duration of the construction works the existing overland raw water main supplying the service reservoir had to be maintained. Once the works quality samples had passed for the new 330m raw water main, it was put into commission and the redundant existing main was removed.
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).
