Next stop - Abbey Mills Pumping Station

Today, you can see the victorian answer to how to get the effluent out of London.
This old pump is just outside the old pump house, and next to the new pump house, here and serves as a canvas for the less artistic grafitti merchants. The DG got there first, as ever, and has the background to them. This shot has both buildings in frame.

I suspect that when it was first used, the effluent was dumped untreated into the Thames.
