We are once again elbows-deep in getting our permanent off grid water system installed. Since we’re moving so quickly, we thought we’d take a moment to explain how the entire system works and components used, before it gets backfilled! This project has turned out to be much larger than we had anticipated, however, we’re trying to do the job right and build as permanent of a system as possible.
