Environment (Nam Saat)

World Health Organization (WHO)

Target Populations/Location
- Pilot households in 15 villages administered by
Don Chanh and Ban Phone Health Centres in Lamam
district of Sekong province.
Project Design
- On-site sodium hypochlorite generation in the
provincial health office and distribution to pilot
households via district health centers and village
health volunteers. Sodium hypochlorite is currently
distributed free of charge without a marketed brand
name nor label. Households dose sodium hypochlorite
to their normal household water storage container,
typically an earthenware pot.
Nam Saat community dialogue on environmental health
and hygiene including household chlorination among
a range of water treatment methods. Community dialogue
also includes training materials illustrating safe
dosing.
Laboratory trials on production, evaluation, effective
dosing, storage and shelf-life extension of 0.6%
sodium hypochlorite generated using an electrolytic
cell.
-
Emergency distribution to low-lying villages during
2002 flooding.
Project Start Date
Results of Project Evaluations
- Approximately 60% and 30% of households respectively
in Don Chanh and Ban Phone health centre areas chose
to participate in the pilot following community
dialogue.
In 2001, 80% of randomly selected pilot households,
or 54% of all households in Don Chanh health centre,
had some free-chlorine residual in their household
water container indicating high daily usage among
participating households. The 2003 evaluation showed
86% of pilot households, or 59% of all households,
had some free-chlorine residual. No thermo-tolerant
faecal coliforms were detected in approximately
70% of samples from households where free-chlorine
residual was detected.
Results indicate technical feasibility and widespread
acceptability of the intervention among the target
population. Based on the findings the pilot could
be expanded to the full safe water systems concept.
