Ballewan Byewash 1 (Former Glasgow Corporation Water Works)

Ballewan Byewash 1, formerly part of the Glasgow Corporation Water Works, was designed by John F Bateman in 1856. This roughly rectangular masonry structure is symmetrically arranged on a sloping site, featuring walls that step up the hillside. At the eastern end, there is a bowed projection, and to the west, there are masonry retaining walls that lead to the outflow channel. The outer face is made of bull-faced snecked red sandstone, while the inner face is polished ashlar, topped with rounded copes.

Inside, there is a central cast-iron trough that carries a conduit between arched openings, which are accented by prominent voussoirs. Shallow steps are located on each side of the trough, and entrance gates are positioned over the arches. The masonry structure is designed to direct the burn to flow underneath the conduit at right angles.
