How to Make, Use, and Reuse an Arborloo
2
Step 1 Make the Concrete Slab

• Create 1 m Diameter ring of bricks and line with
  plastic and place brick/bucket in center.
• Pour in 61 mixture of clean river sand and
  cement
• Insert four reinforcing wires and cover with
  cement/sand mix
• Remove center piece and smooth edges
• Cover with plastic sheet
• Slab must be kept wet and covered for 10 days

Step 2 Make the Ring Beam

• Make an 80 cm inner diameter ring of farm bricks
• Add anthill mortar (anthill soil and water)
  between and above the bricks using a trowel
• Add a second layer of bricks and anthill mortar
• Ring Beams can also be made from a 61 mixture of
  clean river sand and cement and reinforcing wire

Step 3 Installation

• Dig a pit 1-1.5 m deep within the ring beam
• Use excess soil to pack the inside of pit and
  around ring beam
• Pour a large sack of dried leaves into the pit
• Adhere concrete slab to ring beam with anthill
  mortar or 201 mixture of river sand and cement

Step 4 Build the Superstructure

• Use local materials such as poles or grass to
  construct a toilet house with a roof
• This structure not only provides privacy, but
  prevents rainwater from getting into the toilet
  that can attract flies and mosquitoes

6
Step 5 Use

• Add one cup of soil and ash to the pit after
  every bowel movement. This is not required for
  urination
• Leaves should be added at regular intervals to
  assist the composting process
• Food scraps can also be added. Never put trash
  such as plastic or rags in the pit!
• When the pit is nearly full, it is time to move
  the Arborloo!

Step 6 Relocate the Arborloo

• Remove toilet house, concrete slab, and break
  apart ring beam
• Cover the pit with a compacted layer of soil at
  least 150 mm thick
• Reuse toilet house, concrete slab, and bricks
  from ring beam to construct a new Arborloo
• Allow 6-12 months for composting process

Step 7 Results

• After the waste has been composted, fruit tree
  seeds or off shoots can be planted
• Mulberry, guava, mango, paw paw and banana are
  the best trees to plant

Plants grown in regular soil vs. an Alterna Fossa
soil mixture (if you look at the dates on the
plants, the smaller plant was actually planted
one month earlier!)
