13 Places to Wade Into the Wondrous History of Sewers
"The Brussels Sewer Museum lets you tour part of the working sewer system below the city. The subterranean museum contains many old photographs and models of the sewer system’s construction and operation. The most interesting part, though, is the short self-guided tour through some of the working sewer tunnels, with water—and whatever else—flowing beneath." - ATLAS_OBSCURA
