Query: A cheap way to haul drinking water around

Basic plastic 1qt GI canteen. The standard is that a person should drink 2L of water/day; I went with 1qt canteens just to make it easy to keep track of how much water or sports drink I consume when hiking (finish one before lunch, one for lunch/early afternoon, last one for rest of afternoon and evening). These are inexpensive and work. What more do you need? :-)
