P15416: Lightweight Concrete Arborloo

Home

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
