Problem Statement
|
Project Information
|
An arborloo is a moveable pit latrine that composts
human feces into organic fertilizer to provide
nutrients for a fruit-bearing tree. It is
relatively cheap and easy to install in the earth,
allowing a safe and dignified place to defecate,
which in turn should help halt the spread of
pathogens present in human feces. This device
should be portable and light enough to be
transferred between pits. Previous senior design
projects have developed an arborloo that was low
cost and lightweight; it is unfortunately still too
heavy to reasonably carry between market and home,
not tested for all loads, possible to chip, and
could be an aesthetic problem.
- Analyze current design to design a cheap base
that is easy to transport from market to home, and
from pit to pit, by way of being lightweight and
not unwieldy
- Design the base and housing to be durable and
resistant to both weather and pest damage
- Make use of materials that are local to Haiti
- Design a product that is attractive and easy to
purchase (likely to be purchased in parts) to make
Haitian citizens more likely to make use of them,
in turn improving sanitation and health in the area
- Manufacture a working prototype of the base and
shelter fulfilling all criteria
