4. Arborloo A latrine-like sanitation device designed to function over a small pit and to be moved to a new pit when filled Utilize compost by planting tree in used pit Purpose to provide affordable sanitation in poor, underdeveloped areas o Originally designed for use in Zimbabwe

5. Peter Morgan’s Arborloo DIY Project Composition o Bag of cement o “Good river sand” o Thick wire Mounted on a “ring beam” of bricks (mold) Addition of soil, wood ash & leaves creates compost

6. Arborloo Shortcomings Requires installation by mason The slab must be kept covered and wet for up to 10 days before it can be moved and used Expensive

7. Haitian Arborloo/P13414 Problem Statement: design and develop an affordable, element-resistant, portable arborloo that leverages both local and manufactured materials. In addition, the team is aiming to produce a structure that Haitians will want to own. Work led to EPA proposal to investigate more design options.

8. P13414 Summary

9. P14416 Problem Statement Current State o Today’s arborloo takes two days to install and is not easily transportable. The current design is also not socially appealing to the Haitian population. Desired State o Provide an affordable concrete base that is easy to move and install. The desired base should be aesthetically pleasing to users and a worthwhile purchase for sanitation improvements rather than storage or social status. Project goals o Low cost (<$50 to purchase) o Base design that safely covers an 18-20” diameter, 3-4 ft. deep hole o Easily constructed using simple hand tools o Portable o Resistant to environmental damage o Has modular design o Haitians want to purchase Constraints o Proposed budget= $1500 o Base must be relatively lightweight for transportation o Base must be made using concrete

10. Additional Project Deliverables Two completely different prototypes Two molds Design drawings (base and molds) Assembly manuals Bill of Materials Test plan Clearly documented test results Technical paper Poster

12. Use Scenarios Considered  Scenario 1: Arborloo bought by a really poor family and has to carry it for 6 hours from the store to their home.  Scenario 2: Arborloo bought with all the different options, by a “middle class” family trying to show off their social status.  Scenario 3: A contractor is installing multiple Arborloo’s a day and can make more money the faster he installs them.  Scenario 4: A heavy set individual, weighing approximately 250lbs buys an Arborloo and uses it on a daily basis

13. Customer Requirements 9 The system costs less than $50-$100 to users (at production level quantities). The system is lightweight and moveable (by donkey or person walking for up to 6 hours) The system can be installed in less than 4 hours. The system can be installed with simple hand tools. The system confers social status to the owner. 3 The system supports the user over an arborloo hole 18-20” in diameter, 3-4 feet deep The system is safe to use for users (falling, tripping, slipping, moving to new hole). The system keeps pests out of the pit. The system looks “modern” in a Haitian context. The system is welcoming and comfortable. The system can be financed in parts. 1 The system is a product, not a DIY project. The system resists weather and pest damage. The system minimizes environmental impact throughout the lifecycle.

17. Next Steps

18. Issues & Corrective Actions Unlikely will be able to interact with users directly o Will need to get feedback from a variety of sources (individuals who have traveled to Haiti, past projects, other cultural resources) Lack of expertise on concrete and its strength o In contact with Civil Engineers at RIT o Contact with concrete specialist in ME-T program at RIT o Currently waiting for Haitian concrete materials o Research on different types of reinforcement for concrete Questions/Feedback
