From 2003 to 2006, a rural pilot projectwas conducted in Vietnam with technical support from thenon-governmental organization (NGO) InternationalDevelopment Enterprises (IDE) and funding from DanishInternational Development Assistance (DANIDA). The projecttested whether a sanitation marketing approach could improverural access to sanitary toilets in 30 communes in sixdistricts of the coastal provinces of Thanh Hoa and QuangNam. Research for the case study took place between June andAugust 2009. Local sanitation statistics were collected inall study communes. Semi-structured interviews were heldwith the promoters, providers, and some local governmentauthorities. Interviews were held with district andprovincial authorities and at a national level with the NonGovernmental Organizations (NGOs), national authorities, anddonors involved in rural sanitation. With the help ofparticipatory tools, focus group discussions were held withsixty-one householders who had built sanitary toilets orupgraded their unsanitary ones, and sixty householders whohad either no toilet or a still unsanitary one. Finally, thestudy team visited a very small and non-random sample ofinstalled toilets to observe the quality of construction andhygiene as per the national standards of the Ministry of Health.
