a p-trap could easily siphon itself down to the point of no effective trap without a vent. If you're in town then why not just step into the house for a squirt rather than the muss and fuss of maintaining the urinal.
The more and more I think about it and read your guys responses, I think I will give up on the idea of having the urinal. Maybe one day when I build a shop on my property I will do it right with plumbing from the beginning. So if there are any michiganders in need of a urinal, I have one for sale...
Thanks for all of the suggestions and ideas!

)A co-worker and I had a lengthy discussion about this some months back. I have a detached garage in the city and now plumbing running to it. I don't like to go in the hosue with dirty hands to take a leak and get sick of ******* in bottles only to forget about them for a week.
We came up with a pretty interesting idea to make a sink/ urinal combo with a large 55 gallon tank for storage of water. The kicker is that you filter your piss through a series of charcoal, sand and river rock then let it collect in the storage contaner (55 gallon drum on side).
The 55 gallon drum is subdivided between "waste" and "clean" water. Basically, run the system with some clear plastic tube mounted to the side as a level indicator for a month to see where all of the different chemicals (water, grease, oil, piss) seperate in the container, then tap off of it where all of the water settles. This feeds the "clean" water storage which is again filtered.
The idea is that you can piss in the urinal, then wash you hads with that same filtered piss the next day!
Obvious some trial and error will take place and you have to first fill the thing up with a water/ bleach solution to get the water levels up.
The "dirty" storage area (tapped from where you determine the piss, grease and oil settle) get's pumped out every month or so, then top it off with good, clean bleach/ water.
I think it'll work great. A few 120VAC pumps to keep pressure and circulation.
I'll have to draw up the plans and share them.
At my old place I just had a piss tube which was a 6" diameter pipe sunk at a 45 degree angle into some gravel (any Marine or Army vet knows what I mean) and I never had any smell issues since it was outside and got rained on a lot. Do you have to have it inside or could you put it outside with maybe a privacy screen or something?
You can also throw some ice in there during the summer to help dilute the urine.

I have had a porcelin urinal in my garage for a couple years now. A round one from a sailboat. I piped it through the wall and into the ground. Dug a four foot hole (below frost line), put a five gallon bucket in there (punched it full of holes first), put drain line into it, filled with 3/4 gravel, then backfilled hole.
Worked great until last fall.

Can you sketch this out to ensure we understand the system? Did you find the issue?
