Project Summary

Project Background

An estimated 40% of the population does not have access to sanitary toilet systems, which are important for the prevention of diarrheal diseases. The Arborloo is a movable pit latrine designed to be light weight and inexpensive to provide sanitation to poverty stricken people who need it. The latrine will compost human waste to provide fertilizer for a fruit tree. The design of the Arborloo is nearly complete and the product will be ready for field testing by next year. At the moment, the use data will rely on the self-reported responses of the volunteers; such data is known to be unreliable often. Along with this, there is no way to assess the potential environmental impact of the human waste.

Problem Statement

The goal for this project is to design sensors to provide the data that is currently lacking. First, a discrete module to detect and record each use. The second module will periodically measure the conditions of the pit, ideally every hour. The conditions to monitor are humidity, pH temperature and oxygen levels. Both modules will need to be undetectable by users of the latrine while not invading privacy.

Objectives/Scope

• A sensor to count uses of the latrine
• A sensor to monitor the pit conditions

Deliverables

• All design documentation
• Working prototype of the usage counter
• Working Prototype of the pit monitoring module
• Technical Paper
• User Manual

Expected Project Benefits

• Provide accurate data of use to ensure the Arborloo is a worthwhile investment.
• Ensure that the Arborloo will have no effect on the environment.

Constraints and Risks

Constraints

• Budget - $500
• No Power Grid Access
• Weather Resistant
• Two Separate Systems
• Doesn't Invade Privacy
• Low Cost
• Easy to Install and Uninstall
• Easy to Obtain Data

Risks

• Obtaining accurate data through sensors.
• Creating an inconspicuous system.
• Providing easy trouble shooting and repair of system should it malfunction.
