His solution is to go to one of many water-selling depots around town and fill up a few five-gallon jugs from time to time.
Oh, yeah! You're talking about those little, unmanned stands that crop up, right? Those things attract people at all hours of the day. Standing outside a bar, once, around one or two in the morning I witnessed a line of peope, all carrying empty bottles, form. Creepy.
Any idea what those things do to improve the water? Some have UV lights or something, but I don't get how that helps.
