A £2.6 million upgrade of sections of the 45km long Talla Aqueduct used by Scottish Water to supply most of Edinburgh’s water has been completed by contractor George Leslie Ltd, with Jacobs as consulting engineers. Built in Victorian times, the aqueduct takes raw water from the Talla and Fruid reservoirs in the Scottish Borders to Edinburgh’s modern Glencorse water treatment works.
For most of its length the aqueduct runs as a tunnel, split by several bridges and siphons. It is capable of taking up to 127 megalitres of water per day. Following visual inspection of the tunnel and its associated chambers, Scottish Water identified the need to carry out work to refurbish parts of the tunnel and chambers including installing new valves.
Denso Steelcoat 100/400™ was used in 12 different structures and locations to give protection to some 350 linear metres of pipe and various joints and couplings. This follows George Leslie’s previously successful use of Denso Steelcoat in the Loch Katrine aqueducts which serve Glasgow. The Denso Steelcoat 100/400™ System was applied by George Leslie’s own workforce following initial site training by Denso staff.
