The effectiveness of point-of-use water treatment may be limited by declining use over time, particularly when water treatment is introduced via targeted intervention programmes. In order to evaluate the long-term uptake and use of locally produced ceramic water filters in rural Cambodia, we visited households that had received filters as part of NGO-subsidized distribution programmes over a 4 year period from 2002 to 2006. Of the more than 2,000 filters distributed, we visited 506 randomly…

Factors involved in sustained use of point-of-use water disinfection methods: a field study from Flores Island, Indonesia.

A qualitative evaluation of two household water treatment systems, solar disinfection (SODIS) and chlorine tablets (Aquatabs), in three villages was conducted by using a diagnostic tool focusing on technology performance and experience, proving that economic and functional factors were significant in using SODIS, whilst perceptions of economic, taste and odour components were important in Aquatabs use.

Consistent point-of-use water chlorination among households using unimproved water sources and treatment preference in Eastern Ethiopia

Using Waterguard and Bishan Gari in Kersa Health and Demographic Surveillance Site, Eastern Ethiopia, an intervention for consistent use beyond their availability and accessibility to end users is needed.

Water treatment in rural Guatemala: factors associated with the use of biosand water filters

Point-of-use water filters are a means to provide clean water vital to the health of people in developing countries. The factors that influence the adoption of this technology include hygiene

Adherence to Point-of-Use Water Treatment over Short-Term Implementation: Parallel Crossover Trials of Flocculation-Disinfection Sachets in Pakistan and Zambia.

The relatively low and decreasing adherence observed in this study suggests that these products would have provided little protection from waterborne disease risk in these settings, and underscores the challenge of achieving high adherence to POU water treatment, even under conditions of short-term adoption with intensive follow-up.

Ceramic pot filters lifetime study in coastal Guatemala.

A lifetime field study in Guatemala found that disinfection efficacy decreased below the recommended bacterial reduction after 14 months of use because it would not be obvious to users that effectiveness had declined and the follow-up visits by the researchers and the NGO staff appeared to increase consumer acceptance of the CPFs.

Assessing Participant Compliance With Point-of-Use Water Treatment: An Exploratory Investigation

It is suggested that compliance, and therefore disease prevention, can be improved by enhancing perceived benefit to the user.

Microbial and chemical assessment of ceramic and BioSand water filters in rural Cambodia

Unless significant advances are made in the water and sanitation sector, it is unlikely that Cambodia will meet the United Nations Millennium Development Goal (MDG) target #7 for water and

Household water treatment and safe storage – effectiveness and economics

Abstract. Household Water Treatment and safe Storage (HWTS) systems aim to provide safe drinking water in an affordable manner to users where safe piped water supply is either not feasible or not



Local drinking water filters reduce diarrheal disease in Cambodia: a randomized, controlled trial of the ceramic water purifier.

Households using either filter reported significantly less diarrheal disease during the study compared with a control group of households without filters as indicated by longitudinal prevalence ratios.

Preventing diarrhoea with household ceramic water filters: Assessment of a pilot project in Bolivia

Water filters eliminated thermotolerant (faecal) coliforms from almost all intervention households and significantly reduced turbidity, thereby improving water aesthetics and associated with a 45.3% reduction in prevalence of diarrhoea among the study population.

Sustained high levels of stored drinking water treatment and retention of hand-washing knowledge in rural Kenyan households following a clinic-based intervention

Nurses in a maternal and child health clinic in Homa Bay, Kenya were trained in household water chlorination with a locally available, social marketed product and in six steps of proper hand washing, and this brief, practical intervention shows promise for vulnerable populations.

Field test of a silver-impregnated ceramic water filter

The silver-impregnated Ceramic Water Purifier is a low-cost household water filter that removes micro-biological contamination at the point of use that opens the possibility of reaching large numbers of the rural poor through sustainable market channels.

Assessment of the chemical quality of drinking water in Cambodia.

Results of the assessment confirm that there are several parameters of health and aesthetic concern; dissolved arsenic is the most significant and Elevated arsenic levels were detected in aquifers of moderate depth in several highly populated areas, confirming that further investigation of the occurrence of arsenic contamination in Cambodia is warranted.

Impact of the safe water system on water quality in cyclone-affected communities in Madagascar.

Stored water in households using both products had significantly less microbiological contamination than stored water in other households, and the response plan for future disasters should incorporate a transition to recovery and development.

There is now conclusive evidence that simple, acceptable, low-cost interventions at the household and community level are capable of dramatically improving the microbial quality of household stored water and reducing the attendant risks of diarrheal disease and death.
