Interviewer instructions
Circle the code for the most usual source. If several sources are mentioned, probe to determine the most usual source. Note that you can only circle one response code. If the source varies by season, record the source for the season of the interview. If the response is 'Piped into dwelling', 'Piped into compound, yard or plot', or 'Piped to neighbour' circle '11', '12', or '13' respectively, and skip to WS6. If the response is 'Bottled water' circle '91' and continue to the next question. Note that the next question is only asked if the response to this question is 'Bottled water'. For all other responses, skip to WS3.
