Pit Latrines and Water Pumps
Appropriate technology
Diseases associated with contaminated
water are preventable if
1. Water supplies are improved
2. Health education is prevalent
3. Sewage disposal is made safe
But it is essential that the technology used to
promote or improve this is appropriate to a
developing country.
Pit Latrines
• Built using low cost materials - mud walls
and thatch roofs
• A hole in the ground is used to squat over
and the sewage falls into an excavated pit
in the ground
• No water is used and the sewage is
contained in the pit without it
contaminating drinking water supplies
Water Pumps
• Water pumps should be low cost, low
maintenance and low technology
• Locals should be equipped and trained to
fix pumps easily if required
