History Channel's Modern Marvels explores the less-than-polite topic of what happens when you flush.
Meet a man whose job it is to dive in this hidden underworld.
Follow the flow through sewage history.
Experts debunk urban myths and reveal surprising true tales.
A simple flush and it’s forgotten. But haven’t you secretly wondered where it all goes when we go?
Join MODERN MARVELS® to examine the network of underground pipes and tunnels that carries human waste (and much else) away. SEWERS flows through history from ancient Rome’s pristine sewage-conveying systems, through the foul, out-the-window system of Europe in the Middle Ages, and into the revolutionary sanitation engineering of the 19th and 20th centuries. Delve into the sewers of Paris, Boston, and Los Angeles to study waste management’s evolution. Meet a sewer diver (and his robotic counterpart) who inspects and ensures the efficient operation of the conduits; decipher the myths about “treasures” and creatures found in the murky depths; and find out exactly where it goes, how it gets there, and how we’ve learned to use it to our benefit.
