PUREFLOW AMANZI · RESULTS & MONITORING

Beyond the handover.

Safe water is only the beginning.

The real measure is what happens next. We return to households to understand how filters are used, how well they keep working, and where continued support makes a difference.

01 THE WATER REALITY

The reality of
rural water access.

In the monitored Eastern Cape communities, many households relied on untreated rivers, springs and dams, sometimes shared with livestock and vulnerable to contamination. Boiling was the main way families treated drinking water, usually using firewood.

THE PEOPLE BEHIND THE FIGURES

Water access is a
family story.

The monitored households represent 1,678 people. More than half were aged 18 or younger at registration.

02 REACH THAT CAN BE TRACED

Built on trust.
Delivered together.

Safe-water delivery is built around local mobilisation, practical WASH education, user training and registered household handovers. Each event is documented, and follow-up continues after distribution.

03 CHANGES IN DAILY PRACTICE

From boiling
to filtration.

Of the households that had relied on boiling at registration and were reassessed, almost all reported using PureFlow as part of their drinking-water treatment routine.

94.0%

252 of 268 reassessed former boiling households reported using PureFlow, either alone or with occasional boiling.

04 MONITORING BEYOND DELIVERY

Still working.
Still in use.

We went back, then went back again. Two follow-up rounds show how household filter use, functionality and safe practices developed over time.

05 ONGOING CARE

Support that continues
beyond delivery.

Monitoring is not only about collecting information. Field visits identify the guidance, maintenance and practical interventions that help households keep using their systems.

HOW THE EVIDENCE IS BUILT

Grounded in repeat visits.

WHO/UNICEF-ALIGNED MONITORING

Our structured monitoring approach is aligned with the WHO/UNICEF Toolkit for Monitoring and Evaluating Household Water Treatment and Safe Storage, combining baseline assessments, repeated household follow-ups, reported practices and direct field observations.

How were households selected?

Households were randomly selected from registration lists across all 12 Eastern Cape community rollout cohorts in proportion to cohort size. Where selected households were unavailable, replacements were also randomly selected.

What was measured at each visit?

Households reported treatment choices and use frequency. Field teams recorded filter presence and functioning, signs of recent use, correct operation, backwash knowledge, safe storage, and the primary aftercare action required. The four comparisons above use the same 314 reassessed households.

How did the follow-up rounds work?

All selected households completed a first assessment, an average of 6.9 months after handover. Of those, 314 completed a second assessment, an average of 18.8 months after handover. The 12 unavailable households are excluded from second-follow-up results.

The household follow-up percentages refer to the monitored Eastern Cape cohorts. Programme delivery totals cover the Eastern Cape and KwaZulu-Natal.
