The above photo from Ghana shows the poor quality and sanitation of water in rural areas. The article below discusses several strategies to encourage household water treatment in rural communities:
"(Researchers) tested the effectiveness of one-on-one and village-wide encouragement of chlorine use by NGO workers, the importance of social networks in getting people to adopt chlorine, and the impact of paying local promoters to pitch the product within villages. The authors found some interesting things about the first two interventions — village-wide marketing worked slightly better than one-to-one, and community leaders’ chlorine usage appeared to influence other people’s decisions somewhat — but they only led to small and short-term increases in overall usage. Having a local promoter drawn from the village itself, on the other hand, drove up usage both immediately and persistently."
