An excavation team has found evidence of an 11,800-year-old sewer system at the ancient settlement of Boncuklu Tarla East in southeastern Turkey. It has been confirmed to be in a public use area, making this the oldest known sewer system in the world.
It was surrounded by buildings thought to have stood about 23 feet tall and reached up to 8 stories. With that much space comes plenty of people – and their waste.
