The setting out of the line and level of the Talla Aqueduct was done with great precision from observatories, the concrete pillars, a number of which still survive, including one on a steep hillside near Tweedsmuir (NT 106 260) and this one, about a mile south of six others, within a masonry tower near West Linton. The drawing shows its long gone timber superstructure. The brass transit instrument with 30-inch telescope used in setting out the aqueduct is now in the ICE Museum at Heriot-Watt University.
The engineers for the aqueduct were J. & A. Leslie & Reid of Edinburgh and the main contractors were John Best of Edinburgh and Robert McAlpine & Sons, Glasgow.
