Pit toilet update

At last we have restarted work on the long planned five star pit toilet. It has become increasingly urgent for us to have a new toilet hole (the old one is getting uncomfortably near the end of it's usefulness).
Over the previous month or so we have all had a go at digging the pit deeper and wider, and it is almost deep enough at last. Today my (fairly reluctant) partner and eldest daughter were chased outside to begin building the framing for cement frame that will support the floor over the pit. Once the cementing is completed we will lay the floor over the pit (two sheets of really thick ply wood with a hole drilled in one), organize a pedestal (of some sort), put up a temporary shelter and it will be usable. The building part will be put together over the next six months or so.

The start of the frame for cement 'stem walls' to hold the floor up above the moisture and stuff.

Nothing to do with toilets, but our baby guinea fowls have grown up enough to be out in the yard with their mum.

Everyone watches the cement mixer go around and around and around and...

Six or seven mixes later.

It's almost full.

Smoothing out the top.

All done.

Last minute touch ups after the dogs and sheep have inspected the work.

We admire our work as the sun goes down.

The next stage is to dig some more out of the pit (the deeper the better) and to  begin the building of the toilet. I look forward to it.

Just updating this post with a photo or two of the recent digging.

The hole is now 1.4 x 0.8 x 0.9 m; a tiny bit over one cubic metre of hole (I think)

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?
