My great Uncle has a 15 ft diameter water pool with a big volcanic bolder 6 ft tall on a pole hovering just above the water. The water is pumped into the bolder and comes out everywhere and flows into the pool. Volcanic rock is very porous.

A bit more contemporary than the vase or the vw.

My dog dug a toad up at the base of a cottonwood tree. About 1-1/2 ft deep. It filled up and stayed full of clear water until the soil filled in the hole at the end of the summer. Understand the water wicked out of the cottonwood tree.

More traditional, you can do the greek thing of cherub peeing or classic sculptures of nearly nude women pouring water from a vase.

In nature, spring water just comes out of a hole and runs down from there.
