Besides the diameter of the PVC, my pump requires at least 1" of standing water, does there seem to be any problems with this? Or know of another material to replace the rebar besides PVC?

The 500 gallon per hour pump was ample. For those of you with bigger
pumps and high wind problems , try clamping hose and restricting flow as needed. A simple plastic (hot and cold) cup having the correct kind of rolled lip, filled and placed next to the upwards water stream helped direct the flow down and out and made a cool fountain effect. I'm going to gussy it up, run with el wire at night, drill some small holes in the ply, do a cascading fountain and place it in front of our camp next year, . The captions in back adorned our rent-a-rv. Thanks El Subcomandante and crew !

....apparently you are thinking along those lines, do tell!
I did proposed a Fresnel lens evaporation greywater system (and aluminum can smelter) a few years back...
Factors influencing the rate of evaporation
* Concentration of the substance evaporating in the air: If the air already has a high concentration of the substance evaporating, then the given substance will evaporate more slowly.
* Concentration of other substances in the air: If the air is already saturated with other substances, it can have a lower capacity for the substance evaporating.
* Flow rate of air: This is in part related to the concentration points above. If fresh air is moving over the substance all the time, then the concentration of the substance in the air is less likely to go up with time, thus encouraging faster evaporation.
* Concentration of other substances in the liquid: If the liquid contains other substances (such as salts), it will have a lower capacity for evaporation. This is due to Raoult's law.
* Temperature of the substance: If the substance is hotter, then evaporation will be faster.
* Inter-molecular forces: The stronger the forces keeping the molecules together in the liquid state the more energy that must be input in order to evaporate them.
* Surface Area: A substance which has a larger surface area will evaporate faster due to the fact that there are more surface molecules which are able to escape.
