We are actually doing ok on this part. Water is one thing that concerns me most as we don’t have a nearby source should something happen and county water be unavailable. Based on the number in our household and estimating the usage at 3 gallons per person/per day, we have about 4 weeks. While I have not done a trial run, I think my estimate would be achievable.
I am also interested in how to handle water needs for outdoors – like for a garden. I have raised beds and have been considering some type of storage for outdoors. I know you could do rain catchment. Any ideas?
