The buildings were designed by John Henry Chamberlain and William Martin around 1870. The engine house, boiler house, and chimney are Grade II listed buildings. The site is operated by Severn Trent Water. Despite the close proximity to Edgbaston Reservoir there is no current or historical connection of the water.
