Dutch NGO, Foundation Connect International, has published a simple and practical manual for the construction of pit latrines with a focus on slab production. The manual has been tested by the Southern Highlands Participatory Organisation (SHIPO), Connect International’s partner organisation in Tanzania.
The manual can be downloaded here
Comments on the manual are welcome

Great to see detailed plans AND getting away from the deeper, harder to dig, more dangerous and water table contaminating deep latrines.
You have a slope from center to outer edge for strength? With walls (varying materials) would there not be a hygiene problem if washing down the slab (periodically)?
I like the shallow pits because:
-away from water table
-away from heavy soils/clays
-closer to less compacted soils
-can be easily and quickly redug
-can be dug on higher ground without worying about flooding
-less need for specialized tools
-more likely evapotransporation
-more likely root access and degredation
-more aerobic access
-less material to mediate if a problem occurs
-easy to recover lost items, sanitarily
One question: Might there be an appreciable difference between a round slab and a square/rectangular one? Cost, construction durability etc.
TIA
