You will not survive without EMERGENCY WATER STORAGE. It is a historical fact that water utilities fail in disasters due to broken pipes and the lack of electricity to run pumping and treatment facilities. It is also a fact that the government can never prepare for a wide scale disaster. You will be on your own.
Emergency water storage requires a water barrel, water tote, barrel pump, bung wrench, chemicals to treat water, and some method of filtering ground water when your stored water runs out and a water test kit for water testing.
YOU MUST have at least 1 gallon of water per person per day for at least 2 weeks AND PREFERABLY A MONTH. This sounds like a lot of water, but it is not. When the next disaster strikes, a family of four will need one fifty-five gallon barrel to ration over the next two weeks. To live comfortably you would need three or four 55 gallon barrels.
Want to depend on someone else for your security? Keep this in mind. If a moderate to major earthquake hit Los Angeles, California today, and only half of the population lost access to water for two weeks, the government would need to bring in 25,863,740 gallons of water over the two week period just to provide subsistence water. Twenty-five million gallons of water just to survive. That is 1,847,410 gallons of water a day over roadways that will surely be damaged by the earthquake.
