How to build the Arborloo???

Ghana

The Arborloo is a nothing more or less than a simple pit latrine. But it differs in several fundamental ways in its design and the way it is used from the commonly used deep pit latrine.

KNOW-HOW PROCESS
 
Soil, wood ash and leaves are added regularly to the pit in addition to excreta. These aid the composting process considerably. The remarkable conversion from excreta into humus is normally complete well within 12 months of closing off the pit.  The addition of soil and ash on a regular basis also reduce fly and odour nuisance. The Arborloo pit is NOT used as a dumping ground for rubbish like most pit latrines. The dumping of plastic, bottles and rags etc, is not recommended.

Step 1: This is an Arborloo


Start with the brick ring

Step 2: Start with the brick ring

Start with building brick ring beam. The bricks are mortared with local ant hill soil which resists erosion.

The ring completed

Step 3: The ring completed

The ring of bricks is cement mortared around the rim of the pit, preferably cut down into the softer topsoil and built up to at least one course above ground level.

  • Tip: With less experience avoid the use of corbelling and use a 0.8m diameter slab mounted over a 0.6m diameter pit or a one metre diameter slab mounted over a 0.8m diameter pit.

Stabilize Pit with soil

Step 4: Stabilize Pit with soil

The pit is dug out down to 1 – 1.5 metres and the extracted soil placed around the ring beam and rammed in place. The ring beam and surrounding soil will help to make the toilet stable.

The Pit

Step 6: The Pit


Now the slab for the pit

Step 7: Now the slab for the pit

The circle for the 1 metre diameter slab mould is marked on levelled ground and bricks placed together in a circle
 

create a hole

Step 8: create a hole


squat hole

Step 9: squat hole

A mould for the squat hole is made with a bucket or with bricks as shown here. Half the mix (about 17 litres) is added to the mould first and levelled off.

Smoothen slab with trowel

Step 10: Smoothen slab with trowel


Don't forget the wire handles...

Step 11: Don't forget the wire handles...

Two thick wire handles are made up and inserted in the concement can be added around the handles for extra strength.

Keep it wet!

Step 12: Keep it wet!

After an hour or two the mould for the squat
hole is removed and the hole made neat with a trowel.

Transportation of slab

Step 13: Transportation of slab


  • Tip: Rolling it is the most easiest

Installation of slab

Step 14: Installation of slab

     
The slab is then brought close by. A layer of clay, cement or termite mortar is then laid on the ring beam, the slab laid centrally on the ring beam.

Slab installed

Step 15: Slab installed

Now the superstructure must be built around the slab.

Yeah it's strong

Step 16: Yeah it's strong
