In most survival situations, I need water more than I need my survival stuff. After an earthquake, there may be no opportunity to turn on a tap or filter water from a lake for a cold refreshing drink - my nearby lake should be polluted by ruptures to regional sewer lines. To be prepared I need water stored before an event, and not hope to find it after. So stuff that I might store in a nalgene I just store elsewhere. Smelly stuff that attracts critters and bears do just fine in a bear bag, hung from a tree at night.
