The C-Head toilet is available with two options regarding the processing of solid waste. The churning version and the churnless version. One has a churning mechanism to move the medium around (medium = sawdust, wood shavings, peat moss, coco coir, etc.). The churnless does not. Each has its advantages and disadvantages over the other. The difference in cost is $35 with the churnless version being cheaper, so if you are uncertain which version would work best for you, we suggest you get the churning version and modify it into a churnless version for testing. You may want to convert the systems back and forth depending on who is using the toilet. For example, if you are having guests who are not used to using a C-Head, you may want to use the churnless version during their stay for a couple of reasons. So let’s look at the differences.
Building a BoonJon garden takes time. The whole process is designed to be undertaken in affordable stages. The basics are a raised bed or two and a composting tower or two. All the rest, the security fence, the trellises, the work tables, dehydrator system and pathways can be added as you go and may take years. It did for me and this is good because it gives you time to think things out and to experiment and fail on a smaller scale using trial and error. You’ll discover why something works better here rather than there. What grows best when and how much to plant. That is how a permaculture system should grow. But today I want to jump to the topic of pathways and why I chose what I did, specifically gravel chips.
C-Head offers an accessory called a pump tank that is basically a reservoir for urine until it can be pumped out of the toilet to a holding tank or drain field. It is used in situations where the urine must be pumped uphill to its destination. If the situation allowed for a simple gravity feed draining system, then the EUD would suffice. Having to pump urine uphill is common in sailboats under 40 feet and installations in basements or in underground shelters such as prepper bunkers.
If you are not sure if the C-Head will fit in the space you have allotted for your toilet, it is best to make a mock up out of cardboard and test the space. This can be done using a “large” cardboard box available at Home Depot in the storage section of the store. Cut and tape the box to the dimensions shown below. For the wedged back model you will have to make a modification that is not shown by cutting away a portion of the bottom back side 3″ by 3″. For the shorty, make a bucket model and shorten it by 3″.
I came across a wonderful blog site when I googled “Boondocking across America,” called “Roads Less Traveled.” It is a well written, in depth blog site filled with just about everything you could want to know if you are currently boondocking or planning on going boondocking. On this page they link to my website and to a separate blog of theirs that addresses the practicality of using a composting toilet for the purpose of boondocking. The writers confess that they haven’t used a composting toilet and they make their case for using a conventional system, which they have used successfully for many years. I plan on mining their blog site for information in the near future when I get underway on my trip around the states. I went to their article on using composting toilets for boondocking and read it with interest. Here are my observations on their observations and I hope I can correct a lot of misinformation about compact composting toilets, in general, and the show the boondocking benefits of a well designed compact, composting toilet, specifically the C-Head.
In a true permaculture setting, there is no such thing as waste and the same is true for bodily waste. Everything gets used. Keeping in mind that a BoonJon Garden is designed for managing organic waste as well as providing food, let’s look at the elements of the garden and the things that effect the design of your garden. It is important to remember the goal of your garden, which is to provide system for turning carbon based waste back into food and successfully managing the hazards associated with managing organic waste. It is an ongoing learning process. Aside from neighbors and local government, there are three major natural factors that will effect the design of your garden; local climate, the lay of the land, local fauna and flora.
Things you should consider if you have a corner installation.
If you are wanting to install a C-Head in a corner, there are some things that are important to consider. There are basically three kinds of corner installations.
The first is simply installing the toilet in a corner facing out at an angle into the room. This is common with RVs and travel trailers. It can give the room the appearance of more usable foot space or standing room or it may have some other practical reason. In this type of installation the walls are at 90 degrees and extend all the way up perpendicular to the floor. Usually a wedged back or shorty model is used because of the angled back, but a basic model will work just as well if there is plenty of room in the bathroom it will simply stand out two inches further into the room.
