I have been spending some time thinking about how to combine our Jenkins bucket toilet, compost pile, new outhouse and future house Separett Villa toilet. I think I’ve found a possible solution but it would be great to run it past you guys to see if anyone can think why it wouldn’t work.
Our current set up is in a tiny house using the bucket toilet and emptying the contents into a compost pile. The system seems to be working great and we don’t feel like we need to change anything there. It gets a bit weird though when we have guests over or people working in the garden. Nobody seems comfortable using the tiny house toilet, which seems fair considering it’s in a space smaller than most people’s closets, and I think the bucket freaks some people out. It seems like a good addition to our setup to put in an outdoor outhouse type compost toilet. In addition to this we’re planning to start work on our full sized house which will have the Separett Villa urine diverting toilet. Possibly less off putting for guests than the bucket toilet but would keep the same system of emptying into a compost pile.
The idea is to try and combine the compost pile with the outhouse and still use this as the pile for emptying the bucket style toilets. I’m imagining a double chamber compost pile but with a outhouse building on top. We would use one side for a year, then close it up and switch to the other side like with a double vault toilet system. We would like to keep the Jenkins compost pile management, so lots of cover material around the sides and on top after use. At the beginning of starting a new chamber we would prep it by lining the bottom and sides with straw or something similar. The hottest part in the middle would be kept clear by using a cylindrical shaped wrap of hardware cloth attached to the top floor structure. Something that would keep the cover material at the sides, the excrement in the middle but still allow worms and insects to pass through. This way when someone used the toilet it would go straight down the shoot into a hole of straw, and same as when emptying the bucket into the pile. The toilet seat would be on a wooden stand that could easily be moved to the side to allow the emptying of the bucket toilet into the pile, as well as topping up the sides with more straw maybe a couple times a year.
The compost bin part of the structure would be built more or less like a normal compost bin. Cedar posts in the corners to hold the upper outhouse structure up, with wood siding attached to the posts. We’d build a access hatch on the back of the compost bin part to remove compost after a year. It’s basically the Jenkins humanure bucket system, accept we’re removing the bucket part for the people using the outhouse. I know a lot of people have problems with flies and smells, but currently we have neither at our compost pile so I can’t see why this would be any different. I’d plan on keeping it fairly open at the top to allow enough oxygen but not too open that you’d see things dropping down the chute from the outside! We looked at the concrete double vaults, Clivus minimus and wheelie bin designs but didn’t really love all the concrete and plastic used.
I hope I’m explaining this well enough. Happy to draw some plans and sections to help explain.
Any reason why this would be a terrible idea?
