Yeah, you own urine is great for starting a system imho... but if you run the thing on pee permanently, you lose the advantage of all those lovely fish :-(

Oh, and then there is the fact that the supposedly sterile urine passed through definitely unsterile genital regions. So even if you don't have e. coli in your bladder, you may well pass it into the peeponics system. I know, more a problem for the ladies than the gents. But this is why the doctor requesting a urine sample will ask for a "clean catch" sample. Ie, allow the first part of the urine stream to rinse the genital area and pass uncollected. The second part of the urine stream is then collected for the sample.

Steve,
Would the salt content impact on the waste water (solids component) treatment?

You face a far greater risk from somebody else sneezing on you or from hand contact than you do from urine (especially if you use your own).
The toxins the body are trying to get rid of are for the most part nitrogen compounds.

Tony

I would have thought salt buildup would only occur if there is an excess of a particular salt that cannot be used within the system.

Sleepe,
The salt would be from seawater toilet flushing, This would be NaCl in moderately high concentrations.
I do not know if it is used in effluent treatment systems, or if it would cause issues, hence my question.

Sorry Tony :oops:

This thread took some strange twists. I thought the salts you were talking about were from urine.

Q: How much duckweed (transferred to a conventional AP system) could one family grow using their urine in a urineponics setup? Enough to feed how many fish and grow how many vegetables? I wonder if the payoff could be very large one. Imagine your breakfast and lunch foraged out in the world being reused to grow your dinner at home.

Should the topic shift from whether you will get typhoid fever or cholera from your own family's urine to ways of sterilizing it on the way into the system? Is UV the only game in town or would something more primitive work?

Only urine from people with an active (disease organism in the blood stream) are going to shed typhoid or paratyphoid in their urine so if the family doesn't have typhoid to begin with, they are not going to catch it from their own urine.

I'm still researching other dangers and can test for the e coli.

I still suspect that e coli is likely the biggest challenge or danger since we all use/have it in our lower intestine and shed it in faecal matter. The question is, does it survive/multiply in cross contaminated urine?

Most of the other dangers would only come into play if you were collecting urine from a population. For this research I'll stick with the idea that one is collecting their own urine and they are healthy to begin with. If we find that it is viable, then the bigger picture can be looked at.

Do remember that in many places around the world they are already trying to use urine from a population on a large scale as fertilizer. They have been doing quite a lot of research into what dangers there are.

I agree that e. coli is the largest concern. We all have it, and here in the US, we have periodic extensive contamination in the food supply that kills folks every year or two. Not a nice way to go imho.

I approve of using humanure (urine or feces) as fertilizer -IF- it is properly heated, composted, or otherwise sterilized. Interestingly, folks in my ecovillage group are discussing various ways of getting around sewer restrictions. Composting toilets are one option, and I would be perfectly happy using one in my own home. Some of the modern ones are really nice looking, and of course keep useful wastes from going to the sewer.

JP, did you talk to Hundredfold Farm about their wastewater setup? Most of their greenhouse is devoted to it; I'm not sure what their method is, it might just be for graywater.

Haven't talked to them, but yes, I suspect it's just graywater, too.

Ack!!! :oops: I've had a hard drive melt down. So it will be a few days before I'm able to get online like I usually do. (I'm using the other half's computer at the moment to do this quick update.)

Anyway. Small set up running to track the rate of cycling.
12/12/2007
Collected 1 cup fresh urine and diluted in one gallon of rain water. Running in a tiny gurgle garden set up (air pump aerating and lifting small dribbles up to a bed of perlite.)

12/13/2007
Tested pH amonia and Nitrite
pH 6.6
Ammonia above 8ppm
Nitrite 0

12/14/2007
Tested pH, ammonia, Nitrite and Nitrate
pH 8
Ammonia above 8ppm
Nitrite 0ppm
Nitrate 5ppm
I noticed that the clear air hose lifting liquid into the media has turned a bluish tint.

12/16/2007
Tested again
pH 8.2
Ammonia 6ppm
Nitrite ?reading was a little unsure but still close to 0?
Nitrate 10ppm

In some of my reading I found indications that undiluted urine stored for some time will reach a pH of 9 which many seem to believe will render it sterile and safe to use (provided the pH doesn't cause problems for the plants) diluted as a soil fertilizer. I don't know how good that research was or how accurate that information is.

I intend to get water test kit that can test for bacteria so I can add those finding into my reports.

pH of 9 is not going to be good for plants and nutrient uptake. However, an established system will tend to drop in pH. It would be interesting to know where the balance is going to strike.
