The opposite of still water is gaseous or "sparkling" water. Technically though there is no "still" water if the opposite is gaseous water. The reason for this is that most most water known as "still" water contains quite alot of dissolved gas.

Water as a chemical compound has no direct "opposite."However, in the classical "elements" of nature, its opposite would be fire. Thermodynamically, the actual form would be ice.In earth sciences, surfaces that are not predominantly water are called land, although many overlapping environments exist.
The opposite of hydrant (water-releasing structure) could be: -- drain (where water goes, i.e. back out) -- inlet (where water enters the system, as opposed to where it exits)
