Water needs to be stored for two reasons. Water is vital to our existence. We need drinking water, and we need water for household use.
Store bottled water for drinking and for daily use. Keep it rotated.
Fill empty plastic jugs with water for drinking and household use. Use clean containers for drinking water. Water for household use can be put in containers and changed once a year.
Use a large drum for long term water storage. Purchase a siphon so the water may be easily removed for use. A small chemical packet will keep the water fresh for 5 years.
If you do not have source of water near your home, be prepared to catch water from your gutters. You can buy a rain barrel or just use tarps.
A water filter is a must to be sure your water is safe.
You can also store water purification tablets.
