The Pump House
The pump house, built c.1867, contained the important machinery used to empty the dock of water. Inside the pump house was a boiler and a steam engine, which drove one underground centrifugal pump. A tall brick chimney - to release fumes and create a draft for the furnace - once stood on the end of the building.
A furnace stoked with coal or coke heated water in a boiler, producing steam which drove the engine and in turn worked the pump.
When the caisson, or dock gate, was in place, the water was pumped out from the pump well and from there it was released through an outlet pipe into the sea.
It could take up to six hours to empty the dock of 3 million gallons of water.

The steam engine drove an enormous 24-foot (7.3m) cogwheel.
This in turn drove a much smaller wheel, which drove a set of centrifugal pumps in the well. The pumps forced the water along the culverts and out of the dock.
