This facility is in Augsburg, Bavaria, was built in 1876, and has been shut down in no earlier than 2007.
Since then, it's been serving as a technological museum and hydro power station. https://de.wikipedia.org/wiki/Wasserwerk_am_Hochablass
Also makes a fantastic steampunk backdrop for sure.

to browse my shared stuff. You'll find the source files of my images (raw .dng versions, and .pp3 and .png files if edited), as well as unused shots there.
