P13414: Portable Multi-use Shelter


Project Summary Project Information

Project Background:

Sanitation is a serious problem around the world. Nearly 40% of the world does not own a toilet. Past attempts have faced limited success when attempting to provide cheap, desirable options for individuals in rural areas of developing countries. The goal of this project is to improve upon Peter Morgan’s arborloo design by creating a single-person bathroom facility that can be easily transported to its final designation, and installed with a few basic tools. The intent is to develop a low-cost arborloo (less than $50 to purchase) that will encourage Haitians to have better sanitation habits. It is important that this product be a status conferring product so that Haitians will want to purchase and install an arborloo on their property.

Problem Statement:

The primary objective of this project is to design and develop an affordable, element-resistant, portable arborloo that leverages both local and manufactured materials. The shelter should be constructed in such a way that it is easy to move, and disassemble or repair after a hurricane. In addition, the team is aiming to produce a structure that Haitians will want to own.
