Timeline of events that I can piece together (I was late and wasn't aware of the pre-event fluff):
Weeks leading up to July12: Poison is tested in small camps to assess strength. This was likely not "dump into water supply" but more likely "infect a few bottles or someone's dinner and observe."
July 12: Ceruleum explosive destroys a huge chunk of Ul'dah's outer wall. Enemies attack and are met with force.
July 12, 0-30 minutes post-diversion: Jin'li and possible others skulk around Ul'dah and crack open barrels of poison, dumping them into the water supply.
30~ Minutes post-diversion: Jin'li is approached by a guard and questioned. A story that sounds plausible is given but the barrel is hauled away for investigation.
45~ minutes post-diversion: More barrels are discovered, Jin'li is discovered in the city walls. At this point it isn't known what's been done but the clues are in place to discern the water supply has been tempered with.
60~m post-diversion: Immortal Flames and Red Wings spread word officially to not use any water for any reason. Aya had a head start on them and spread word on the way to the Quicksand, I believe.
The window for people to have been affected is small, but if we're pretending Ul'dah's got the dimensions of a real city and not an MMO one, there's still plenty of room for people to get infected.
It's my personal feelings that the majority of folks would have been hiding out out of fear of the attack and not gargling shower water, but there's always gotta be That Guy so he's probably dead by now.
