- Boiling: Household Water Treatment Options in Developing Countries. January 2009. CDC Safewater/USAID. (pdf, 538KB). Boiling is arguably the oldest and most commonly practiced household water
treatment method, and it has been widely promoted for decades. Organizations
recommend boiling both for water treatment in developing countries and to
provide safe drinking water in emergency situations throughout the world.
- Filtration & Chlorination Systems: Household Water Treatment Options in Developing Countries. January 2009. CDC Safewater/USAID. (pdf, 150KB). Several household water treatment systems incorporate both a physical filtration step for
particle removal and a chlorination step for disinfection. This dual approach leads to high
quality treated water.
- Safe Storage of Drinking Water: Preventing Diarrheal Disease in Developing Countries. January 2009. CDC Safewater/USAID. (pdf, 254KB). Safe storage options fall into three general categories: 1) existing water storage containers in the home; 2) water storage
containers used in the community and modified by an intervention program; or, 3) commercial safe storage containers
purchased by the program and distributed to users.
- Simple Options to Remove Turbidity: Preventing Diarrheal Disease in Developing Countries. January 2009. CDC Safewater/USAID. (pdf, 173KB). Filtration or flocculation remove particles and reduce turbidity. These pretreatment
methods may also increase the efficacy of household water treatment products by removing contaminants that
interfere with disinfection and physical filtration processes.
- Targeting Appropriate Interventions to Minimize Deterioration of Drinking-water Quality in Developing Countries, IN: J HEALTH POPUL NUTR 2008, (pdf, full-text) - This paper proposes a semi-quantified ‘disease risk index’ (DRI) designed to identify communities or households that are ‘most at risk’ from consuming recontaminated drinking-water.
- A Community-based Bacteriological Study of Quality of Drinking-water and Its Feedback to a Rural Community in Western Maharashtra, India, IN:
J HEALTH POPUL NUTR 2008 (pdf, full-text) - A longitudinal study of the bacteriological quality of rural water supplies was undertaken for a movement towards self-help against diseases, such as diarrhoea, and improved water management through increased community participation. Three hundred and thirteen water samples from different sources, such as well, tank, community standpost, handpumps, percolation lakes, and streams, and from households were collected from six villages in Maharashtra, India, over a one-year period.
- Point of Use Household Drinking Water Filtration: A Practical, Effective Solution for Providing Sustained Access to Safe Drinking Water in the Developing World (pdf, 103KB) IN: Environmental Science & Technology, May 13, 2008 - Web Release Date. by Mark D. Sobsey, Christine E. Stauber, Lisa M. Casanova, Joseph M. Brown, and Mark A. Elliott - The lack of safe water creates a tremendous burden of diarrheal disease and other debilitating, life-threatening illnesses for people in the developing world. Point-of-use (POU) water treatment technology has emerged as an approach that empowers people and communities without access to safe water to improve water quality by treating it in the home. Several POU technologies are available, but, except for boiling, none have achieved sustained, large-scale use. Sustained use is essential if household water treatment technology (HWT) is to provide continued protection, but it is difficult to achieve. The most effective, widely promoted and used POU HWTs are critically examined according to specified criteria for performance and sustainability. Ceramic and biosand household water filters are identified as most effective according to the evaluation criteria applied and as having the greatest potential to become widely used and sustainable for improving household water quality to reduce waterborne disease and death.
- Water Quality Interventions to Prevent Diarrhoea: Cost and Cost-Effectiveness. 2008. T. Clasen and L. Laurence Haller. Geneva: World Health Organization. (pdf, full-text) - Building on our recent Cochrane review of the effectiveness of water quality interventions to
prevent diarrhoea, we collected cost information from
28 country programmes and computed the cost-effectiveness of conventional improvements of water
quality at the source (well, borehole, communal stand post) and four interventions to improve water
quality at the household level (chlorination, filtration, solar disinfection and combined
flocculation/disinfection).
- Microbiological Effectiveness and Cost of Boiling to Disinfect Drinking Water in Rural Vietnam, by T. Clasen, et. al. IN: Env Sci Tech June 2008. (pdf, full-text) - We assessed the
microbiological effectiveness and cost of boiling among a
vulnerable population relying on unimproved water sources
and commonly practicing boiling as a means of disinfecting
water. In a 12 week study among 50 households from a rural
community in Vietnam, boiling was associated with a 97% reduction
in geometric mean thermotolerant coliforms (TTCs) (p <
0.001). Despite high levels of faecal contamination in source
water, 37% of stored water samples from self-reported boilers
met the WHO standard for safe drinking water (0 TTC/100
mL), and 38.3% fell within the low risk category (1–10 TTC/100
mL). Nevertheless, 60.5% of stored drinking water samples
were positive for TTC, with 22.2% falling into the medium risk
category (11–100 TTC/100 mL).
- Difficulties in Bringing Point-of-Use Water Treatment to Scale in Rural Guatemala. Stephen P. Luby, Carlos Mendoza, Bruce H. Keswick, Tom M. Chiller, AND R. Mike Hoekstra. Am. J. Trop. Med. Hyg., 78(3), March 2008, pp. 382-387. In an earlier study in rural Guatemala, 257 households that received flocculant-disinfectant to treat their drinking water had 39% less diarrhea than 257 control households. Three weeks after completion of the study, national marketing of the flocculant-disinfectant was extended into the study communities. Six months later, we assessed frequency of and characteristics associated with purchase and use of the flocculant-disinfectant by revisiting the original study households and administering a questionnaire. Four hundred sixty-two households (90%) completed the follow-up survey; 22 households (5%) purchased the flocculant-disinfectant within the preceding 2 weeks and used it within the last week. Neither being randomized to the intervention group during the efficacy study nor combined spending on laundry soap, toothpaste, and hand soap in the preceding week was associated with active repeat use. Even after efficacy was demonstrated within their community and an aggressive sophisticated marketing approach, few households purchased flocculant-disinfectant for point-of-use water treatment.
- Household water treatment and safe storage: a review of current implementation practices. by D. Lantagne, R. Quick and E. Mintz. IN: Water Stories: Expanding Opportunities in Small-Scale Water and Sanitation Projects, a report by the Wilson Center's Navigating Peace Initiative, examines alternatives to large-scale infrastructure projects in the water and sanitation sectors. Woodrow Wilson Center, August 2007.
USAID Sponsored Activities/Reports
- USAID Safe Water Partnerships - Every year there are over 1.6 million deaths from diarrhea related to unsafe water, sanitation, and hygiene — the vast majority among children under five years of age. To address this critical public health issue, USAID is engaged in a range of partnerships to improve water quality and hygiene.
