Latrine diagnosis:

• ∆ = Pit latrine with superstructure (roof, wall, door)
• O = Pit latrine with no superstructure

Minimum and mandatory standards:

• Pit latrines must be a minimum of 6 m from dwellings
• Latrines must be at least 30m far from any ground water sources
• The depth of the pit must not be less than 2 m in order to avoid fly breading (Except when stony ground prevent digging)
• The super structure can be built from simple locally available materials, such as bamboo, wattle or from corrugated iron sheet, timber etc.

Advise for proper and effective latrines but not mandatory:

• Roofs can be made of plastic sheeting, split bamboo, concrete or zinc sheeting
• Door should be at least 60 cm, width and 1.70 cm height
• The drop hole for faeces should have proper cover to prevent entry of insects into the hole and should be kept covered except during use.
