I'm totally new to prepping. I've known I should be doing it for a long time but I'm the world's worst procrastinator. I recently read One Second After and it made me realize just how bad it is to be unprepared. I'm going to start with water storage. My thoughts are to get some of the blue 55 gallon drums and store them under my house in the crawl space. I should be able to get at least 300 gallons worth, maybe more that way. I will build some racks for them and I'm planning on filling them with the water hose. My main question is do I need to do anything to treat the barrels first? Do I need to do anything to treat the water before, during, and if we need to drink any of the water in an emergency? Of course it's dark under there, and the temps should stay relatively moderate too. Do I need to worry about rodents, or other pests? I know rats will eat through a lot of things but will they be attracted to these barrels? One of my reasons for doing it this way is we are limited on room, I can secure that area pretty easily, and I can set the whole thing up without any neighbors noticing so hopefully that will prevent any conflicts in the case of a disaster. I will also probably store food there too. I just feel the need to get some water storage quickly so I want to start there. Thanks in advance for your answers.
