How much grey water tank for 2 day stay

[karadean]

I cannot find it written anywhere that waste water from sinks and showers can’t be drained overboard in a lake in New Mexico. Can anyone enlighten me? This has only been a problem this year. I am not talking about black water from a toilet, just wash water. All of a sudden, the park officers are requiring our drains to be permanently sealed. I say, show me in writing and no one can.

Another reference point, probably high end: we have a 90 liter (24 US gal) holding tank and it's good for 8 to 10 person-days.

That's for everything including my beer consumption, and with a Vacu-flush toilet. So a more conservative approach should need less capacity.

If urine is sterile, why don't people just drink it over and over again?

The law says, if you pee or poop into a container, tank, toilet, etc., it cannot be dumped overboard within three miles of shore. There is a loophole in the law that does not make it illegal if you pee or poop directly into the water without putting it in a container first.

Note: That's Federal law. States and localities can impose stricter laws for bodies of water entirely within their jurisdiction.

Its sterile in a healthy person.

Survivalists will drink it, anyone in a life or death situation will.

It tastes awful (but not as bad as you think, don't ask me how I know) and contains salt.

Its not infinitely recycleable.

Same reason you don't drink sea water. It's loaded with salt.

Actually, on the space station they do but only after processing to remove the salt.

First off, after listening to the numbers being thrown around I am realizing that there is entirely too much fiber on our boat!

As others have said as long as you disable the ability to discharge in some way you should be good. They make marine all in one units. If they are full-ish they are not fun. I have never used a composting toilet but hear nice things.

As to urine being sterile. That is a little more fuzzy. It does have bacteria that is normally found in the bladder. If there are any... problems they will be in there as well. I don't think drinking it is a good idea, even in a survival situation. I am not sure what the TDS levels are in urine, but I am guessing that they are in the same order of magnitude as seawater. Especially if you are dehydrated. I know that some cultures use drinking of urine for various reasons. I am just saying do a little more research before that becomes your go to plan.
