Urine into gray water?

I'm going to have my sink and shower water in a guest cottage flow into an in-ground gray water basin. I'm wondering if I could have a urinal flow into that as well so that my sawdust toilet is spared large volumes of urine. Any opinions on diverting urine to gray water systems?

I can't see how that could cause any problems at all. I pee directly on crops with no problems, I would think what you want to do would be fine.

Is it just a mulch basin or something like that? I think you'd be fine doing that. Even if your greywater is feeding plants I think it would be OK. If it was a lot of pure urine, maybe not. But since it will be just a small volume of the greywater, and especially if it's just a guest cottage, I can't see the harm. But I'm no greywater expert.

What I'm planning is to have separate pee/poo toilets (I really don't like the "urine diverter" setups I've seen), with the pee drain leading to a bucket full of sawdust, or maybe into a straw bale, which when saturated can be composted.

I believe if the water has urine in it, it's not gray water but yellow water. And the best words on this topic were written by the late Frank Zappa:

It might be a mulch basin I'm still trying to figure that out. I was thinking of using a brewers funnel for the urinal:

I'm wondering if running a line directly from this, out the wall, and into the graywater without a trap will result in odor? I was thinking of "flushing" the system with a glass of water or something. Clear I'm in the early stages of this thing

That's actually my plan too. Make a trap from 3/4" pipe or so, and flush it with a cup of water so the trap isn't full of pee.

After seeing this:

I think I'll go ahead and run water to mine and have a trap.

For a flushing system on the "men's" toilet at his lake house he hung a pump sprayer with a mix of bleach and water to keep the smell down. The urinal was simply an inverted gallon bleach bottle with the bottom cut out so the urine would flow out what would normally be the top of the bottle down a hose into a 5 gal bucket filled with pea gravel and sand. The bottom of the 5 gal bucket had several very small holes drilled in the bottom to let the waste flow into the ground. It was very simple, cost effective and worked like a champ.
