You flush, it’s gone… right? Not exactly. Follow The Flush lets you track what happens after the handle goes down—mapping the underground route your wastewater takes from your home (or any address you enter) through local sewers, neighborhoods, and municipalities on its way to ALCOSAN’s treatment facility.

Along the way, you’ll see just how far it travels—and how long that trip can take—turning an everyday habit into a surprising look at the hidden infrastructure working 24/7 beneath our feet.
