For general summary of Loch Katrine (reservoir), see NN41SW 29.
The growth of Glasgow and the subsequent need for unpolluted water for both human and industrial consumption, resulted in the decision to build an aqueduct to provide water to the city. Loch Katrine was chosen to be the source of the supply. The system was inaugurated by Queen Victoria on the 14 October 1859. By 1883 an additional supply from Loch Katrine was needed due to the increased consumption of water by the city. An additional aqueduct was constructed in 1885. The new system, measuring 23.5 miles in length, was officially opened on 21st June 1901.

Loch Katrine aqueduct, Blairuskin junction chamber: Junction chambers provide maintenance access to both aqueducts and to the short junction channel that connects both the 1855 and the 1885 aqueducts. They can also be used for re-routing water flow. This particular chamber has the usual shaft with hemispherical grille (above the 1885 aqueduct for air and open-air access), access stairs and three glass rooflights (lighting the 1855 aqueduct access).
