I get my water by gravity and for free from a creek, it goes to my 2,500 gallons container and from there to my 550 gallons container and then to my garage where I have a larger water filter and the preassure pump to send it into my house where I have another filter under my kitchen sink and another filter in my water jug in my frig. Water is the most important item that you will need in what is to come so make sure to secure your source of water. If you live in a apartment then a king size water bed under your regular bed would be the way to go.....if it goes bad then for toilet and washing up. If you live in a larger apartment bldg that has a large water tank on the roof then with a few friends get ready to secured the water tank....be armed. Remember that if power goes out there would be no water because you need power to send the preassurise water out, specially to the third and higher ffloors. Water will be the "Blue Oil" of tomorrow........we can live without oil, but not without water.
