How to … design a sanitation app | Source: The Guardian, March 22, 2013 |
Trémolet Consulting won the London leg of the 2012 Sanitation Hackathon. The team explain how to take your mobile app idea from concept to creation
As we write this, we’re contemplating the prospect of a trip to the Silicon Valley to meet potential investors for a mobile phone application (app) we’ve designed. The app aims to help answer one of the biggest unresolved questions for understanding sanitation
markets in developing countries: how much do households invest in their own sanitation facilities?

It all started when we submitted a problem statement at the London leg of the Sanitation Hackathon, an event that took place simultaneously in 14 cities around the world in early December 2012. Hackathons are increasingly used by international agencies or governments to get computer programmers and app developers applying their creative brains to solve a social issue. The “watsan” (water and sanitation) hackathon dates back to 2011 when the World Bank organised the firstwater hackathon. Since then, mobile phone apps have made their mark in the water sector, particularly for water point mapping.
The idea we submitted to the hackathon stemmed from what we’ve observed as a lack of data on households’ investment and recurrent expenditure on latrines, despite the fact that they often represent a major proportion of total investment in the sanitation sector. It is critical to understand how much households are investing, and in what, in order to design appropriate policies and programmes to support them. We seized the opportunity of the London sanitation hackathon to see whether that app (a computer programme connected to the internet that runs on smartphones and other mobile devices), now known as ‘SIT’ (Sanitation Investment Tracker) had the potential to make a significant contribution to the way sanitation programmes are designed, run and monitored.
On World WaterDay, 22 March, the World Bank announced the Top 10 Finalists of the Sanitation Hackathon App Challenge. The challenge is a follow-up to the Sanitation Hackathon, which attracted over 1,100 developers in December 2012 to solve sanitation problems.
The Top 10 Finalists apps are:
- Empowering Girls monitors girls’ school attendance to track appropriate sanitation facilities.
- LION Sync provides decision-makers with access to real-time data online and offline.
- LooRewards promotes sanitary behavior by rewarding safe sanitation practices.
- mSchool monitors the status of water and sanitation infrastructure in schools.
- mSewage crowdsources the identification of open defecation sites and sewage outflows.
- San-Trac reminds users about hygienic practices and gathers real-time data for trend analysis (winner of the People’s Choice Award)
- Sanitation Investment Tracker tracks investment and expenditure in sanitation at the household level.
- SunClean teaches sanitary and hygienic behavior through games for children.
- Taarifa enables citizen reporting and tracks decision-makers’ feedback.
- Toilight finds toilets in a smart and easy way.

The Grand Prize Award winners will be announced on April 19, on the eve of the World Bank’s Spring Meetings.
