ollas are unglazed clay pots, with no drain-hole. you bury them in your garden, fill them with water, and they slowly leak providing slow, steady water to the root-zone.
now......imagine if you will...........(in my best rod serling voice)..........a giant 50 gallon olla, slab-built up with local clay, raku fired in situ, and then buried in a berm. the over-flow from my collection tank will run down the slope in buried clay pipe, filling olla berms along the way. much further research is planned, but i think the core idea is sound. by the time the olla degraded, it will no longer be vital; the berm will be established.
