Not chemically. Elements and compounds do not have opposites.
However, in classical alchemy, the opposite of water (primarily cold) is fire (primarily hot). This is based on the original concept of four elements of matter: earth, air, fire, and water.
Astrology uses a different basis for establishing "opposite" signs.
the opposite of hydrophobic is hydrophylic
The opposite of transpiration is absorption, where plants take in water and nutrients from the soil.
Evaporation is the opposite of condensation.
The opposite of urine would be something like clean water or another substance that is not waste or bodily fluid.
The opposite phase change is condensation. Evaporation is the change in phase from liquid to gas. Condensation is the change in phase from gas to liquid.
The opposite of water resistance would be water permeability, meaning that water can easily pass through or penetrate the material.
The opposite would be to desaturate or unsaturate. For water, the opposite could be to dry.
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. Put simply the opposite of still water sparkling, that it's gaseous contain can be seen and/or felt as sensation in the mouth.

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.
