A major upgrade of parts of the 45km-long Talla aqueduct has been completed.
Built in Victorian times, the structure takes water from the Talla and Fruid reservoirs in the Borders to Glencorse Water Treatment Works, which opened in 2012. For most of its length the aqueduct runs as a tunnel, split by several bridges and siphons.
The £2.6million upgrade involved repairs to bridges and some structural work to the aqueduct, as well the installation of new valves and flooring in its chambers, helping to safeguard its future and security of water supply to customers .
