Behavioral Messaging | Sanitation Hackathon

Behavioral Messaging

Short description 

A tool to send sanitation and hygiene promotional messages to key population segments at key times. 

Crisis statement 

Tanzania is a diverse country with various religious, ethnic, and socio-economic groups.  These bring differences related to sanitation and hygiene behaviors in terms of preferred options, usage habits, and coverage.  To be effective, sanitation promotional messages need to be evidence-based and appropriate to the target audience. For example, a message to a resident in Kiteto district may prompt households to build a new improved latrine to comply with the elders’ wishes; while for Arusha residents, the message might focus on improving existing latrines to avoid the embarrassment of having visitors seeing an old unsafe latrine.  The widespread ownership of mobile phones, especially among local leaders and sanitation promotion teams, brings an opportunity to deliver multiple messages and behavior cues to specific segments of the population.  Doing so could effectively could help to improve the lives of millions. 

Needs statement 


A database, program, or app is needed that can store key sanitation information – behavioral drivers, barriers, key messages, etc. that are appropriate to the majority of residents in a geographic area of the country.  The program would also be able to send SMSs or initiate Robo calls containing behavioral cue and sanitation promotion information to contacts organized by geographic areas at certain times  The geographic areas could be by Region (22 in Tanzania) or District (132 in Tanzania).

Data sources:

List of Tanzania regions and districts

Sanitation characteristics of two regions


Requirements and considerations:

May require collaboration with mobile phone companies

Must take into account the network availability in the country

Must take into account the level of technology available to target audiences

Program needs to be easier updatable to change sanitation characteristics, messages and contacts used


Impact statement 

The user of this tool would be the government of Tanzania, specifically the Ministry of Health and Social Welfare (MOHSW) and the Prime Minister’s Office for Local Government (PMO RALG) for use within the National Sanitation Campaign and beyond.  There is backing for this tool from development partners such as the World Bank, WSP, UNICEF, WaterAid, and Care

In addition to possible Hackathon prizes, there could be further incubation, testing and rollout support for high-potential solutions as part of the implementation of Tanzania’s National Sanitation Campaign.
