Rainwater

When you have no electricity, your canned food supply has run out and the grocery store shelves have been emptied; having a garden could save a starving stomach. Knowing how to start this life saving garden would be the first step.

We don’t really appreciate how much water we use, until we don’t have it to use anymore. Water is the keystone to all survival – we cannot live more than a couple days without it, we cannot raise crops or livestock without it, and we cannot keep clean and free of diseases without it.

Rainwater collection, or harvesting rainwater, is simply collecting the run-off rainwater from a structure to store for future use. This water can be used in a multitude of ways. When purified, rainwater can be used for various household activities; including drinking and cooking. Since rainwater is quite clean, deep purification isn't always necessary, especially when used for irrigation, gardening, or laundry.

Water is the most plentiful element on Earth, covering nearly 75 percent of the surface. The bad news? most of it is salt water or polluted.
