Historical Information

The construction of the Mourne Conduit, which brought water to Belfast from the Annalong and Kilkeel rivers, was advertised by the Belfast City & District Water Commissioners in 1896. This well house is one of four identical structures on the conduit, the others being at Moneydarragh More Upper (HB 16/1/61), Tullybranigan (HB 18/13/71), and Ballykine (HB 18/6/13); there is also a fifth at Dunnywater (HB 16/1/51) . All appear to have been designed by BCDWC Engineer L.L. Macassey and were erected in the second half of the 1890s. They came into service with the opening of the service reservoir at Knockbreckan in October 1901. This well house is at the south end of the Bow Lough siphon (a piped section of conduit carrying the water underground across a valley). It contains a valve which automatically regulates the flow of water into the siphon pipe (and thus the internal water pressure), and also cut it off when necessary for inspection purposes. It was constructed by Messrs Fisher and LeFanu, who were also responsible for the laying of this section of the conduit.
