Pissing in Drinking Water

Disgusting thought, isn't it? Yet we do it every single day!

Municipalities spend hundreds of thousands of dollars to provide safe drinking water to our homes, and what do we do? We urinate and defecate in it, via the porcelain throne. Then, of course, that once-safe drinking water is now "contaminated" and hundreds of thousands more dollars are spent to get rid of it, either by municipal sewage systems or a gazillion home septic systems.

Consider this: the urine and solid matters we eliminate are made up of nutrients including nitrogen, potassium and phosphorus that either our bodies haven't used, or that are by-products of our digestive systems. Those liquids and solids contain lots of nutrients, just like the animal manure we put in compost piles. Our urine, in fact, is actually sterile. "Urine can contain up to 90 percent of the N (nitrogen), up to 50 percent of the P (phosphorus) and up to 70 percent of the K (potassium) present in human excreta." (Source)

While we throw away all the nitrogen, phosphorus and potassium we have added to our drinking water, we also go out and buy manufactured nitrogen, phosphorus and potassium, aka fertilizer, in bags to put on our gardens to grow green plants. HUH?? 

"This waste is particularly worrisome now because the cheaper sources of commercial fertilizer for farming are declining. Competing uses for natural gas, our biggest source of nitrogen fertilizer, is driving up prices. Potash deposits in Canada, our handiest source, are declining, and talk of opening up new mines in the rainforest does not sit well with the environmental community. Some specialized phosphorus fertilizers are very expensive. The day is coming when we must start thinking about scrupulously saving our wastes for fertilizer as humans have done, especially in Asia, for centuries." ~Gene Logsdon

So why do we use our very expensive drinking water as a vehicle to throw away those nutrients?

Simple answer: fear and ignorance... plus a healthy dose of "comfort zone" boundaries coupled with inertia.

When the liquid and/or dry ingredients are collected from home in a safe manner, it can be odorless, cheap and sustainable, both for us and the planet we inhabit. (Please do not confuse the toxic material from public waste treatment plants as acceptable or the same thing. Those waste systems contain many materials dumped in the system like drugs, paints, solvents, cleaning agents, oils, and who knows what else, in addition to human excrement.)

Human waste material can be collected in a fancy composting toilet like the one pictured above made by environlet™ (where the works are hidden), or even in a simple but adequate bucket with a lid. The liquid components can be collected separately or together in the bucket.

In the bucket method, if waste is covered immediately with a carbon material like sawdust, coconut coir or peat moss, it will have no odor even if it remains in the bathroom until the container is full enough to empty. When enough is collected, it can be put in a dark-colored plastic 55 gallon barrel and allowed to compost in the sun for 9 months to a year, or it can be put in a well-managed garden compost pile... and either way, when it is fully composted is just like the stuff from our regular garden compost piles... FREE, and sustainable!

Liquid waste material, aka urine, can be collected separately and used immediately as fertilizer in the garden, BUT it needs to be diluted about 1:10 with WATER so it doesn't burn plants. It doesn't have to be diluted with the expensive drinking water we buy either (whether from the city, our own electric-powered well pumps, or in bottles from a store). It can be collected rain water, or water from a creek or even a puddle. You just don't want to burn the plants.

I have read a little about humanure for many years, and always dismissed the concept, but thinking it would fit in a rustic, off-grid situation. I never really looked at the realities of the nutrients we throw away, only to buy the same soil nutrients from a garden store. Nor did I consider the implications of trashing those nutrients in perfectly good drinking water!

However, now that I AM aware, it will boil down to a matter of how far I'm willing exceed my comfort zone to be a better steward and increase my efforts at sustainability.

Realistically, I can't add a composting toilet to my bathroom (space-wise) unless I removed the existing toilet, but that could be a project for next summer when the temps are warmer and I can put up a temporary outdoor "bucket" facility. Another restraining factor is that I co-own this house with my half-sister and she'll balk at the thought, even though she has her own private bathroom.

I just might install a composting toilet to my private bathroom in spring or summer anyway if I can afford it (in spite of any objections my sis may have) because a new porcelain throne could be re-installed later for any potential resale of the property, and the nutrient benefits I would gain are worth it!


I could, however, begin now to collect my urine, and add it diluted for nutrients my garden soil every day... even now during winter since our ground seldom freezes solid for more than a few days. As a matter of fact, I did collect urine for most of 1 day, and added it diluted to a cold compost pile the day after Christmas. Not sure I want to do that every day until I can get a good system.

(I should mention I have not read the books listed below, so I'm not sure of safety measures or procedures of collecting urine inside and keeping it for more than a day.)

Given the increasing shortage and cost of fertilizers, and the expense of clean, potable water almost everywhere, does it make sense to keep pissing in our drinking water?

Notes:
There are some problems in making these nutrients safe when they are just mixed together and dumped in a pit, as was typical in the smelly and probably toxic outhouses of generations past. The Humanure Handbook by Joseph Jenkins recommends collecting dry and liquid matter together in a carbon matrix, and adding them to a garden compost bin weekly using some safe guidelines. He also has a website for more information and photos.

Gene Logsdon, a contrary farmer whom I admire, has just written Holy Shit: Managing Manure to Save Mankind, and it's on my WishList.

Mr. Logsdon has this to say just about the impact of just pet waste products:

What are we throwing away in money? In Holy Shit I use my own way to come up with a figure. Experts say that ten tons of animal manure and bedding per year can adequately fertilize an acre of farmland. Therefore we have enough pet manure in this country to fertilize something like 20 million acres every year. If a farmer is paying out $100 an acre for commercial fertilizer (right now it’s lower than that, last year higher) we’re talking about a value for pet manure of something like two billion bucks.

And the cost of throwing it away in the landfill or sewage treatment system is a whole lot more.

ps...
The conceptual image of "pissing in drinking water" is not an original thought of mine; it came from Nick Ritar in a TEDx talk.
