פירוש על עבודה זרה 93:20

Water which belongs to the public cannot become prohibited. So his question must refer to water that bubbles up from the ground on the property of a private person. While the Talmud does not say so, there is no answer to this question either. This is the end of this series of highly theoretical and abstract questions. I thought they were quite interesting and served as a window to the thinking of late amoraim.
