D5 and D6: Main source of drinking water:
Here you must find out from the respondent what the main source of drinking water is for the members of the dwelling unit. This should first be asked and recorded for the wet season and then similarly for the dry season.
Fill in the appropriate code for the main source of drinking water during the wet season in column D5 and that for the dry season in column D6. Never leave any of these spaces blank, even if the codes for wet and dry season are the same.
