Glasgow sewage works

"I then proceeded to grab the upended Imp by its slimy ankles (being careful not to besmirch my lime green robes) and threw it into the Clyde where it floundered most satisfyingly before dragging itself on to the opposite bank and fleeing in the direction of the nearby sewage works."

- Gilderoy Lockhart, Marauding with Monsters

There was a sewage works plant in Glasgow, Scotland.

In Marauding with Monsters, Gilderoy Lockhart wrote about his adventures along the banks of the River Clyde in search of the Weetimorousbeastie, ending up defeating an Imp colony instead. According to him, the leader of the Imps ran away to the nearby sewage works. The veracity of these events is doubtful, given Lockhart's theft of other people's achievements.
