Our first goal is WATER STORAGE.
You purchased or began collecting containers for water storage.
Fill those containers up! As long as the containers are clean, there is no need to add bleach or anything else. I usually do a quick rinse before adding the water.
I know this information is also included in previous posts, but I thought a quick reminder would be good. Don't place your water containers directly on a concrete floor. Instead place them on untreated wood or pallets. And remember not to store them next to any chemicals. If you are storing them outside leave a little head-room for freezing. One last reminder: It's a good idea to replace the water each year. Water tastes bad after long storage. If you don't, and end up needing to use your water, just pour some of the water back and forth from one container to another (this aerates the water and makes it taste better).
