Gates And Walls, Aqueduct Intake Including Railings, Loch Arklet

The gates and walls at the aqueduct intake, located at Loch Arklet, were designed by James M Gale and J R Sutherland between 1910 and 1915. This structure has a curved, closed U-shape and extends into Loch Arklet. The external wall is made of large, coursed, bull-faced masonry or concrete blocks below the water level, while above the water level, there is a series of low segmental red sandstone arches topped with a band course and parapet. On either side of the structure, there are two projecting buttress sections flanking the sluice entrance.

On the land side, a coped sandstone ashlar boundary wall creates a large enclosure, featuring a central cast-iron foot gate. Inside, there is a deep semicircular basin with steep stepped side walls on the north, south, and west sides, which are surmounted by low segmental arches that support a broad, paved footway. The west wall has two square-headed sluice openings at the bottom, while the east side features a round-arched exit channel with prominent voussoirs, heavy pilaster buttresses, and a shallow pediment. The basin is surrounded by cast-iron railings, and there is a sluice mechanism located at the west end.
