Water is an important part of “The Big 3 of Survival” (Food, Water and Shelter). The human body can only survive three (3) days without water. For this Water Module, I wanted to leverage “The Rule of Three” with regard to water filtration/purification, storage and physical water. I have three methods of filtering water and three storage containers for the water. During an emergency situation, you can assume that some of your preparedness measures will fail you for whatever reason. If that were to happen, the rule of 3 would help ensure that you backup plan and your backup to the backup plan is still usable. I also wanted to make the gear for this module as light as possible, without sacrificing quality, since water itself is so heavy (e.g., 1 liter of water weighs 2.2 pounds / 1 kg). The system I have was designed to allow for many liters of water to be stored and little effort needed for the filtration process.
