IntroductionIntroduction

• Frequency of extreme floods and cyclones are

increasing• When the existing drinking water systems are

microbiologically contaminated water increases

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.



Research objectiveResearch objective

and WPT (commonly distributed)

• Housewives o PUR recipients were

provided with training

• Data collected

by:

(i)

interviewing

about use, knowledge, acceptance

,

TTC and (iii) diarr. prevalence among

PUR, WPT and Comparison children

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

•
