Saving water with ollas is a great idea. This series of videos from High Desert Garden shows how to do it easily and inexpensively. High Desert Garden also created a video showing how to make your own ollas from clay, but using terracotta pots is less expensive, faster and easier.
Ollas will buffer the water needs of a garden, but realistically they are not large enough to get you through the day, so High Desert Garden uses an ingenious method of feeding the closed ollas from a larger reservoir.
