Variations in water pricing are a serious issue.
More affluent areas [of developing cities] pay on average 3–4 times less than poorer areas
not on the piped system. Without new legislation, it is difficult to see how this disparity can
be addressed.
Replacing tankered water at each site is achieved by supporting private and public sector
water vendors, via NGO partnerships. The question now is how the poorest members of
the camps can afford this water. [2]
