When and if the grid goes down, the first thing that will be evident is, of course electricity, but in a few minutes you will realize that you have no water. It doesn't matter whether you are on a municpal system or a well, you are in the same situation. A generator will let you pump water from a well or spring. Water is the most necessary element to life as we know it. You can go several days without food, but not very long without water. We all take it for granted, as it is as close as our sink or refrigerator, but when it is not there, we will soon be wanting it.For those who live close enough to a stream, creek, river or lake, you can walk and go get water. Even water from a farm pond is better than no water at all. You can put rainbarrels under your downspouts and catch rainwater in an emergency or for watering you plants or garden during a drought, when watering is banned. You can live without electricity but not water. people in past times used cisterns, well and springs to get their water, and these can still be utilized. If obtaining water tha hs not been purified you will need to boil it for a few minutes or add chlorine bleach(1 capful to a gallon), shake it and let it sit a few minutes before drinking it. You can also use the water purification tablets to make your water safe. There are also water purification bottles and pumps that will eliminate most of the viruses and contamination in the water. Most have charcoal filters to make the water more palatable, too. Many types of nasty bugs inhabit our water and these will make you very sick without first treating it, so as a precaution it is always better to treat the water before drinking it, unless it comes from a reliable source. Everyone should have a plan in effect to obtain water in times of need. Making preparations now will eliminate confusion and undecidedness when and if it happens. Good luck. rockhound
