Haiti Reconstruction

Rebuilding Haiti must start from the ground up, with agricultural education

Family Composting Toilet Program

Family composting toilet Pilot program

6 families in Gris Gris will be perfecting a pilot program before it will be implemented to entire communities.

They will discuss what is working and find what will work better with each step of both the toilets for indoor use keeping smells away and toilets clean.

We will try to use dry vetiver leaves that are chopped finely to use for the Dry  carbon that covers the smell.

Each time someone uses the toilet to poop they cover their deification with shredded dry vetiver leaves or other compound that has dry carbon content such saw dust.

When buckets are full they will be put onto a protected compost pile behind vetiver hedgerows.   These hedgerows must have no openings so all water is filtered through the grass.

Our picture shows a cut out view so you can see the layers but both side of the compost pile must be protected.  If not by vetiver on the sides you can use wood sides.

The first layer should be about 10 cm thick of sticks to let air under the pile.

Then you have to add about 5 cm mat of dried vetiver grass on top of stick layer.  Put another 5-10 cm mat on sides of live vetiver to keep humanure from burning live grass.

When you buckets are full you add to compost pile by dumping Humanure on top of green vegetation such as weeds or chopped up spent banana trees.

After each bucket you dump sprinkle 2 handfuls of crushed limestone on top of humanure.  When you have all your manure on pile you have to cover it with dry vetiver grass. 

Do not dump next bucket on top of dry carbon layer.   Before you start a new layer of humanure on top of old layer, push back clean dry carbon to sides for new layer exposing the last layer of humanure. 

Add another green layer made of green weeds or waste.  Dump next layer of humanure and re-cover with dry carbon when finished.

Compost piles can be kept in wooden containers but this is wasteful and vetiver gives better protection. These picture shows sawdust but you will run out of this quickly.  Only use sawdust for covering humanure after use with toilets. 

These next pictures are to show you how to wash buckets and add water to the compost pile.  We want you to use this method on our protected vetiver piles.

Do not dump next bucket on top of dry carbon layer as shown on this picture, first add green vegetation layer.

Before you start a new layer of human manure on top of old layer, push back clean dry carbon to sides for new layer exposing the last layer of human manure. 

Add another green layer made of green weeds or waste.  Dump nest layer of humanure and re-cover with dry carbon when finished.

Compost piles can be kept in wooden containers but this is wasteful and vetiver gives better protection. These picture shows sawdust but you will run out of this quickly.  Only use sawdust for covering caca after use with toilets. 

Whenever you finish dumping buckets clean the buckets with water then scrub them with a brush and rinse again.  All water is to be dumped on the heating compost pile.  Do not dump soap or detergent on compost pile or it will kill microorganisms.

Clean buckets and set them upside down to dry before reusing.  Fill bottom of bucket with thin layer of dry shredded vetiver leaves for easier cleaning.

When finishing every layer be sure to re-cover with dry vetiver to keep smell and flies away.  Compost needs some moisture to heat correctly but too much moisture is not good.  In rainy season you may have to cover the pile with a tarp.  Best moisture content of 40-60% by weight is best for composting. At lower moisture levels, microbial activity is limited. At higher levels, the process is likely to become anaerobic and foul-smelling.

Toilet paper can be composted but may take longer to disappear without a lot of turning compost.  Also urinating in separate container than poop may make less smell and can be added to compost later or mixed with water and put directly in garden.
