In previous section, a simplified approach to survey design for
WASH primary data collection has been outlined. The goal of the
discussionfirst focuses on providing statistical robustness of the
methodology. To do this, we compute basic statistical parameters, in
which also base the definition of criteria that will help validate the
collected data from the viewpoint of decision-making. Second, and
with the aim of communicating clear messages to policy-makers, a
number of alternatives to disseminate achieved results are presented.
