Water is such an important aspect of our lives. We often take for granted that if we turn a faucet ,we have water. What happens though if something affects our supply? Do you keep bottled water on hand? If so how much? The average adult needs 64-96 ounces of water per day to maintain adequate hydration. The average disaster response time is 72 hours. Water can be easily stored in bottles. Keeping a few cases on hand in a closet may just be the difference between a "happy you and a very sick or dead you." In the event of a major storm or other disaster do you know where to obtain water if you run out of a supply and that faucet doesn't work? Do you know how to purify water with limited resources? Here is a nice article explaining what you can do. http://www.wildwoodsurvival.com/survival/water/purification.html
Some areas we may not think of looking for water is the back of a toilet. Most toilets hold 2-8 gallons of water in the reservoir. In an urban environment there are a lot of toilets! Maybe you have a waterway near you. A simple charcoal fish tank filter cartridge, I like these Whisper Biobags ( http://www.thatpetplace.com/whisper-bio-bag-cartridge-large-12pk-unassembled?gdftrk=gdfV2226_a_7c268_a_7c6967_a_7c242828&ne_ppc_id=1463&ne_key_id=26722480&gclid=CKCv3Iu4xL0CFY6Rfgodx4EAaw) can be used to help filter water and if you can boil it or add a drop of bleach that will go a long way to keeping you from becoming ill. A few basic and inexpensive supplies like a clorox pen, a filter pad and a lighter can mean the difference between safe and unsafe water.
Remember often times official aide will take several days to arrive. Be prepared and be safe.
