Another idea for those not avers to compost and keen on saving water is the 'humanure toilet'. Basically it's a bucket that you excrete into, and cover with organic matter (fresh sawdust is best). Put sawdust in the bottom of the bucket, and a toilet seat on top. Every time you make a deposit, cover it up with sawdust. If it smells, you need to add more sawdust. It doesn't smell at all if you make sure it's covered. Empty your bucket onto the compost pile with everything else, and make sure it's covered up with sawdust (Sawdust is your carbon input).
DO NOT TURN THIS COMPOST!
Once the compost pile is full, leave it for a year. If in doubt, leave it for another year.
Put it on your veggies. (Of course, if you are worried, put it on your fruit trees. Also, if you take any serious medication, you may not want to use it as compost.)
We did this last summer and it is AMAZING! Great compost, great bathroom, and no water use.
There is an online book about how to do it properly:
