Project Summary Project Information

Project Background

A large portion of the world's population has no access to sanitary toilet systems. Because of this, preventable diseases are able to cause immense damage in underdeveloped regions of the world.

One solution to this problem is the arborloo, a movable pit latrine which collects human waste to use for compost, and in doing so keeps pathogens from the waste from entering drinking water. The arborloo is lightweight and inexpensive, allowing it to be moved by a small group of people and available even for impoverished families.

A previous MSD team, P15416, created a lightweight base for the arborloo. This was followed by P18416 creating a mold system for creating multiple arborloos for low cost. Funding has been created for testing the system with 100 families in Haiti. Over a period of a year, data will be gathered on the performance of the arborloos on the usability of the compost, and its effectiveness as a pathogen deterrent.

Problem Definition

This project focuses on the data acquisition system to be placed inside the compost pit. This system should be able to monitor the number of times the arborloo is used, the temperature and moisture in the pit, and if possible the pH and oxygen content of the pit. The device must be independently powered, preferably by batteries, and consume low enough power to last the long periods of time between data being gathered. Above all, this device must be inexpensive.
