Description

The weir with inlet pipes at King George Pumping Station, located adjacent to King George Reservoir, was opened in 1913 and designed by William Booth Bryan for the Metropolitan Water Board. It features an Italianate granite balustrade set on an English bond brick wall, positioned above four cast-iron outlet pipes with upturned ends. These pipes direct water into a brick chamber that has a chamfered granite sill, allowing the water to flow down a cascade into the reservoir. The weir is flanked by stepped brick walls topped with granite coping.
