Development, Testing, and Validation of eSOS Emergency Sanitation System

Project Result / Case Study | 15 January 2016

This Pilot and Demonstration Activity (PDA) covers two distinct activities. First is to test and validate the eSOS emergency sanitation business model as an innovative decision-making support tool responding to emergency situations, as well as a cost-effective provision of sanitation to informal settlements and temporary situations like large religious and public events. The second is to manufacture, test and validate this innovative toilet and come closer to the final level of market readiness.

Report Card

Completed in January 2016, this PDA:

  • Tested and validated the eSOS emergency sanitation business model as an innovative decision-making support tool responding to emergency situations, as well as an affordable sanitation solution to informal settlements and temporary situations in times of emergencies before, during, and after disasters. an appropriate public-private partnership business model involving various stakeholders for operating and maintaining the activated carbon plant
  • Successfully manufactured, tested and validated this innovative toilet through observable data over a specific test period.

Description

The eSOS business model consists of smart toilets, an intelligent excreta collection vehicle tracking system, a decentralized excreta treatment facility, an emergency sanitation coordination centre, and an integrated eSOS communication and management system. The number of sanitation units deployed will be initially determined using rules of thumb (e.g. 20-50 people per unit per day), but the application of eSOS will very soon provide practical feedback on these rules as much more data become available. Some of the activities to be conducted in developing the business model include: identification/mapping of needs and costs associated with emergency sanitation; setting default model parameters; building up a user interface; testing the business model; verification of results; and reporting and dissemination of the project results.

Testing of the eSOS Smart Toilet entails a set of conditions that need to be fulfilled, including durability, ease of use, quick installation and deployability, inexpensive, safe to use, provides sufficient privacy, among others. The project component also includes manufacturing, field testing and validation of the innovative experimental eSOS smart toilet.

The experimental toilet was manufactured and tested in The Netherlands. Field (case study) testing and validation of the business model was conducted in a refugee camp in Tacloban City in the Philippines over a period of three months.
