There was a statistically significant relationship between wealth group and the type of water supply used (as the main drinking water source in the dry season) by urban households (P-value <0.001; see Table 1), with the richest (above minimum wage) group making more use of unimproved sources (23% of households at or above minimum wage) and other groups making more use of public standposts. This relationship may partly relate to the purchase of water from tanker truck vendors by better-off families, and will be investigated through further research.
