A great example of establishing water resiliency with a well and simple pump setup.
From engineer775's YouTube Channel:
Here is a pump house/garden shed to protect the well plumbing and to house a manifold for an irrigation system and backup water supply. The retreat will be able to get water from the submersible pump on grid, generator off grid, simple pump manual handle or simple pump with 12v motor and Solar Charging batteries to run the motor and a 2500 gal. tank that is located 60 ft above the highest spigot so there can be a gravity fed water system for weeks at a time.
