  • Pour Flush Toilets Eradicate Typhoid in Katunguru Village

    Katunguru village reduced Cholera and Typhoid outbreaks by building and transitioning to pour flush toilets rather than pit latrines.

In addition to stopping disease outbreaks, residues from filled pits are used as manure and ash from kitchens are sprinkled inside after each use to prevent odors and dry up waste residues. Pour flush toilets are not constructed with wood, so they also minimize local deforestation.
