I've been looking into it more, and I'm under the impression a current study is underway (or recently completed) in Hawaii, to assess the Evap-trans-spiration? (what a word) rates in Hawaii. The typical locals for such a system are more Arid climates that generally have less rainfall than can be easily evaporated.
However, Most of Hawai'i has lower relative humidity rates than one might think (55-70%) Which should leave ample room for plenty of evaporation. Especially if you are spec'd to cover a portion/all of your system with a clear poly-carb roof. Then it gets the heat/sun but no rain. It would dump many many gallons of moisture to the air daily. Also winds and breezes have a large effect as well.
I'm trying to get a rough estimate for the amount of surface area you need against the type of plants that are on it to evaporate a given amount of water.
I just don't have the time to dig deep enough to get a rough idea yet. However I am optimistic this maybe workable. Especially once you factor in the new'ish grey water allowances. You are only looking at sink water and black water to contend with. If that is the case, and you have a low-flow toilet, you could be into the 30-70 gallon per day range for a 2 bedroom house of black water. (of course most of us use much less) This could be a pretty reasonably sized system I'm guessing.
Here is hoping!
