In this section, the harmonized questions are presented in three parts: questions related to drinking-water, to sanitation, and a question on the disposal of children’s faeces. The harmonized questions for drinking-water provide information about the type of water source used, the time required to collect the water, and the household member responsible for fetching the water. There is also a question about the treatment of household drinking-water. The sanitation-related questions focus on access to sanitation facilities, and include questions about the type of sanitation facility used by the household and whether the facility is shared with others. The harmonized question on children’s faeces aims at understanding household practices for disposing of them.
