Short drop toilets

This may be a bit of a taboo subject in polite society...but it is a very important subject for those of us who choose to be responsible for as much of our own lives as possible; toilet designs.
Until recently I have been happy using a short-drop toilet design on our block; this consists of a vase shaped hole about 1.25 meters deep, 60 cm wide at the bottom and tapering to about 40 cm wide at the top. On top of this pit is placed a movable pedestal made from half a plastic live barrel with a toilet seat bolted on top. A tarp stretched over a poly pipe hoop frame completes the set up. We 'flush' by sprinkling a can of lime over the contents to lower the pH and make the contents more worm friendly and less fly friendly. This kind of toilet means that I have to dig a new hole every school holidays.

Lately I have been experimenting with adding compost worms to the mix. Once a new hole is dug and in use for a week or so, I tip in one container of compost worms from the worm farm at school. This makes the hole last roughly twice as long as previously; presently 20 weeks is the record. This means I have to dig less and can avoid the deconstructing and reconstructing of the toilet for a bit longer.

My new plan consists of digging a big enough pit to hold a year's worth of...well....contents, and adding worms to that. I am hoping this will allow enough time for the worms to reduce the contents to worm castings and baby worms, which will then burrow away to seek a new life in a far off place, thus keeping the pit level to an acceptable level permanently (or at least a very long time). Then I can build a more permanent and attractive structure over the top of the pit.

According to the World Health Organisation Pit Latrine Designs, when digging a pit toilet you should allow  0.06 m3 per person per year. In our house that equates to (0.06 x 4 = 0.24 m3) to allow for visitor usage as well. This isn't a huge hole really. I have calculated this to be about the size of a 240 liter fridge.

I am currently digging away at the pit for this toilet and will post more photos as I get to each stage. The ground is very hard at the moment due to the dry weather so going is slow. The next question will be "What do I build the toilet shed out of?"

Do you take responsibility for your own waste?
Would you like to?
Any ideas or comments welcome.

stage two Hugelkultur bed in progress

Today has been a lot of fun; we cleared up a pile of saplings from the front yard that had been cut down because they were shading the solar panels. My partner had a rare day off, so I made him cut up the whole pile of saplings with his handy chainsaw.

 The saplings became my next Hugelkultur bed.

In the process of cleaning up the saplings I decided to use an old half tank as a Hugelkultur bed too.

Then my sister rang and offered me some good red soil from her holiday home (just up the road) so off we went to pick it up.

Red soil from my sister.

Tomorrow's adventure is to get all that lovely soil into the stage two bed and mulch it over.
I really need to get some seeds and seedlings soon!
I am really enjoying this process.

Stage one of the Hugelkultur experiment complete

Today I have had a lot of fun. My daughter and I dug some more soil from the future toilet pit to finish off the stage one hugelkultur bed. You can see from the photo how rich the soil is down near the dam.

Soil added to the bed

Amazed and delighted sheep

Then we spent a while cleaning old straw (well, compost now) out of the sheep shelter, much to the amazement and delight of the sheep. This became the mulch for our new bed, and the whole lot was watered in well.

doesn't that look pretty?

Tomorrow I will spread blood and bone and then let the planting begin!!

Then its on to stage two; build another bed next to that one and so on until the chook runs are full.
