Tank

There are a couple of tanks used to feed the water that gets pumped by the power house. One of them, the "settling tank", apparenlty isn't really needed these days, but served a certain rather crucial purpose when the harbour was more like an open sewer. I'm sure you can figure it out. The other, the header tank, is above the visititor centre in the room behind the wall there.

The powerful electric pumps in this room then use the water to raise the weight of a hydraulic accumulator (I don't know if the one inside the tower in this building is still used, but there's one outside that you can see being raised by the pumping—we'll see it in a bit.)
