What to do with the waste fluid?

What do you do with all your waste fluid after you wash the biodiesel?

Right down the drain

Isn't it hazardous though? Glycerine, methanol, phosphates?

You asked about water wash. Unless you have developed a new way to wash with glycerine, methanol, and phoshate, water wash is WATER.

Yes, some residual methanol and trace glycerine will be present. It wont harm a thing, especially in a municipal system.

Ok, just wondering. I didn't know how much glycerine comes out. I have a septic system.

Well, then you will have clean pipes!
Water and glycerine make a wonderful cleaner/degreaser. Not necessarily in the ration that it will occur in the wash water, but none the less.

Here are some other uses for glycerol (long read, but sort thru it)

One that may not be in the link provided, is that glycerol blended with 50% WMO works well in atomizing furnaces, I.e Cleanburn, etc.
When heated above 140, the mix flows well and produces a tremendous amount of BTU's, for virtually FREE.

i could be way off my rocker here, but when i was looking into playing with bio, the best idea i had read about was basically taking the wase, be it wash water or the by product and boil the hell outta it (turkey frier would work well) from what i was reading the liquid was the hazard issue and it was "ok" to have it evap, and you could trash the solid waste no questions asked

Not entirely accurate, but close.
If using potasium hydroxide it can be composted, if demthed first.
Bioling of of methanol in open air is probably not wise. If you are going to heat the glycerol, you could just as well distill it, and reuse it.
