Exploring the Hidden Infrastructure Beneath New York City Streets
What's Under Your Feet in New York City?
I take you on a tour beneath Manhattan to reveal the massive root system of water and power that keeps the city running. We examine why water mains run at high pressure to prevent contamination and how New York's unique underground electrical networks differ from standard radial systems. From gravity-fed water sources to submerged transformers, this hidden world is essential for the city's daily survival.
You want any crack, hole, or break in a water main to be a one-way street; if anything is moving from one side of the pipe wall to the other, it is pretty important that it happens from in to out.

That's where the mutants live. Also, there's a thousand year old, old New York City buried underneath that had bathroom booths with phones in them.
