Description

The sluice gates and flanking walls at the intake from The Lea Navigation to King George Pumping Station were opened in 1913 and designed by William Booth Bryan for the Metropolitan Water Board. The structure features cast-iron sluice gates in front of an Italianate granite balustrade, which has pyramidal caps on the end and corner piers. Water flows from the sluice gates into a concrete channel and then into five pumping chambers located next to the "Humphrey" engine pits of the Pump House. This site is included for its group value.
