Around here, apartments, condos, duplexes, and pretty much everyone else has installed individual water meters to get away from run-away utility cost increases. Only a small handful of places come with water provided until you get out into the country where wells dominate.

A cheap 1.6 toilet that flushes well is under $100 and an easy enough job that I would replace an older one anyway, then take it to a non-profit recycle store for a tax write-off. Within under a year the whole thing pays for itself and the savings keep coming in. Guess I should have said that in my first reply!
