The BBC has featured old photographs found in a skip that show one of Scotland’s most important public works, the Katrine acqueduct, being built.
BBC News writes:
The photos show the construction of one of the Katrine Aqueducts, which take water to treatment works that supply 1.3 million people around Glasgow. The aqueducts were part of a radical 19th Century plan to supply fresh water from Loch Katrine to Glasgow, 35 miles away. The glass photograph slides show work on the second phase of the project, which began in the 1880s. The slides were thrown out when Scottish Water’s former west of Scotland offices, at Balmore Road in Possilpark, Glasgow, were being closed.
They include images of workers boring through rocky hillsides with drills during the construction of the 23.5 mile-long second aqueduct, which began in 1885 and was completed in 1901. Before the construction of the water supply system in 1859, the majority of Scotland’s largest city took its drinking water from a small number of public wells supplied by the River Clyde…
The first aqueduct includes tunnels through mountainous terrain in the shadow of Ben Lomond and bridges over the valleys. A second aqueduct was constructed decades later to accommodate the rapid expansion of Glasgow… The entire Katrine Aqueduct scheme cost £3.2m to build which would be about £320m in today’s prices.
