The world’s largest freshwater lake is lake Baikal, with a volume of 22995 km^3. Adult humans have a bladder volume of about 350 ml. If a single person pees in this lake once, that’s a concentration of about 1.5*10-17, or about 150 billion times too pissy.
Reverse osmosis and distillation have fairly complimentary strengths and weaknesses. RO removes about 99% of contaminants, distillation removes about 99.9%. two passes each of RO and distillation and your treated single-piss lake Baikal water is now down to about 1*10^-27 piss, or still about 10x too pissy for you.
This analysis assumes that you consider piss to not include the water molecules that carry it. If you have a “once piss always piss” policy, I’d be willing to bet that a pretty significant portion of water to have gone through an animal at least once.
My piss goes to a leach field by way of a septic tank. So no worries about that. Got municipal source repumped from a station about 10 miles west, so I dunno what the pipe conditions are here yet. Have only had to replace one water heater line so far
Your acceptable concentration is about 1*10^-28.
