Key Issues and ChallengesKey Issues and Challenges
• The investment needs will increase with the increase in
frequency
of
disasters.• The length of emergency water period and its
contexts, types of disaster, etc)
• Emergency is
a managerial
term,
demanding
decision
and follow‐up in terms of extra‐ordinary measures
• Usually household POU is regarded as a simple approach.
• But POU is a technology; local contexts will determine its
performance.

ConclusionsConclusions
• Reconfirmed household POU device as an effective
emergency water approach, provided it is used properly
• PUR was a new method and required more work than
the WPT rate of use of PUR was hi her than WPT.
• Housewives /women managed the POUs
• Training on
use
of
POU
was
rare
• eve o correct now e ge a out use o was g er among PUR than among WPT users.
• Probably training on PUR contributed to its higher rate of
use compared
to
that
of
WPT
• POUs were not adequately distributed
•
