Although it'd be hard not to notice before the leak is even halfway through one swimming pool worth. On AWS it's fairly easy for the charges to rack up for quite a while. (Also, at least around here if the water agency notices abnormal flow for a long time they drive by and if they see a leak they shut off the water. Happened to me once when a sprinkler pipe blew out.)
