Unsafe drinking water contributes to diarrheal disease and is a major cause of morbidity and mortality in low-income contexts, especially among children under five years of age. Household-level water treatment interventions have previously been deployed in Rwanda to address microbial contamination of drinking water. In this paper, we describe an effort to integrate best practices regarding distribution and promotion of a household water filter with an on-going health behavior messaging program. We describe the implementation of this program and highlight key roles including the evaluators who secured overall funding and conducted a water quality and health impact trial, the promoters who were experts in the technology and behavioral messaging, and the implementers who were responsible for product distribution and education. In January 2019, 1023 LifeStraw Family 2.0 household water filters were distributed in 30 villages in the Rwamagana District of Rwanda. Approximately a year after distribution, 99.5% of filters were present in the household, and water was observed in 95.1% of filters. Compared to another recent water filter program in Rwanda, a lighter-touch engagement with households and supervision of data collection was observed, while also costing approximately twice per household compared to the predecessor program.

Background. Diarrheal diseases are still one of the major causes of morbidity in under-five children in sub-Saharan Africa. In Ethiopia, diarrhea is responsible for 9% of all deaths and is the major cause of under-five mortality. Objective. To assess the impact of community-led total sanitation and hygiene on the prevalence of diarrheal disease and factors associated among under-five children in Gamo Gofa Zone. Methods. Community-based comparative cross-sectional study design was used to compare the impact of community-led total sanitation and hygiene intervention on under-five diarrheal disease. Multistage sampling method was employed. The data were collected by using pretested structured questionnaires. Data quality was ensured by daily supervision completeness and consistency. The data were coded, entered, and cleaned by using Epi Info version 7 and were analyzed by using SPSS version 20. Bivariate and multivariable analyses were carried out by using binary logistic regression. Significance was declared by using p value of <0.05 and AOR with 95% confidence intervals. Results. The response rate of this study was 93.3%. The overall diarrhea prevalence was 27.5% (CI = (24.06, 30.97)) which was 18.9% (CI = (14.94, 23.2)) in implemented and 36.2%. (CI = (30.41, 41.59)) in nonimplemented woredas. Children whose age was between 12 and 23 months (AOR = 1.6) and greater than 24 months (AOR = 5), availability of handwashing facilities (AOR = 4), disposal of waste in open field (AOR = 9.7), unimproved source of drinking water (AOR = 6.5), using only water for handwashing (AOR = 6), children who started complementary feeding less than 6 months (AOR = 5.6) and greater than 6 months (AOR = 5.2), and utensils used to feed children such as bottle (AOR = 3.9) were the factors positively associated with diarrhea. Conclusion. The overall prevalence of under-five diarrhea was 27.5%. The prevalence was low in CLTSH woredas as compared with non-CLTSH woredas. The study showed that handwashing facility, using only water for handwashing, open refuse disposal, and unimproved source of drinking water among under-five had a statistically significant association with diarrhea occurrence in CLTSH nonimplemented areas. Integrated efforts are needed from the Ministry of Health together with the WASH Project in improving drinking water, handwashing facilities, and solid waste disposal practices.

<p>Tuning the characteristics of granular activated carbon bed (GAC-bed) in household water-filters would be a technique to maintain iron at the required-level in drinking water. In the present study the individual effects of the depth of GAC-bed and the size and porosity of GAC particles on the iron removing capacity are investigated experimentally. A spectrophotometer is used to measure iron-content in water. It is observed that iron removing capacity increases monotonically with the increase in bed-depth regardless of the size of GAC particles. It is also observed that the iron removing capacity decreases drastically with the increase in the size of GAC particles for any fixed bed-depth. Finally the porosity of GAC particles is found to affect the iron removing capacity. The higher the GAC porosity the higher is the iron removing capacity over the considered porosity-range. It is believed that the observations of present study would be useful in adjusting GAC-bed characteristics at the time of designing household water-filters to maintain iron at the required-level.</p><p>Chemical Engineering Research Bulletin 18(2015) 1-5</p>

Treatment of drinking water at the point of use (POU) has demonstrated health benefits for people who have access only to microbially contaminated drinking water. In this work, the ceramic siphon POU water filter was evaluated for its ability to reduce indicator microorganisms in test waters. During batch challenge tests, the filter reduced Escherichia coli in filtered water by 7 log10 (99.999987%) and bacteriophage MS2 by 0.12 log10 (24.0%). Next, a novel continuous flow dosing system allowing sewage-amended feed water to constantly pass through the filters allowed for determination of changes in microbial reductions over time and total volume of water filtered. E. coli B, MS2 and fluorescent microspheres (as a surrogate for Cryptosporidium oocysts) were seeded into test water and dosed to filters at 10, 25 and 50% of the filter's volume lifespan. Microbial removal efficacy decreased as the volume of water filtered increased and test filters did not achieve their volume lifespan before physically failing. The ceramic siphon household water filter is effective in reducing E. coli and surrogates for Cryptosporidium in water, but filter modifications may be needed to achieve acceptable levels of virus removal and to reach the target 7,000 L volume lifespan of the filter.

Abstract Many households in Nigeria lack access to safe drinking water. Sixty-three percent (63%) of the nation's population live in rural areas where only 3% of households have access to safely managed drinking water. This suggests an urgent need for intervention to offer sustainable solutions to drinking water needs at household levels. An operational research was commissioned by the United Nations Children's Fund (UNICEF) Nigeria to generate evidence to inform and guide Water, Sanitation and Hygiene (WASH) programming on household water quality. This involved an assessment of local manufacturing of household water filters; factors influencing social acceptability and market opportunities for clay and biosand water filters in Nigeria. Implementation of the research recommendations by the filter factories resulted in improved bacterial removal efficiency (&gt;97%) in filters. Factors such as filter design and efficiency were shown to influence acceptability of filters, which influenced the price at which users were willing to pay for the filters in the study areas. The market research indicated low popularity of the filters due to lack of promotion and marketing of the water filters. The research outcomes show great potential for sustainability and marketability of clay and biosand water filters for household water treatment in Nigeria.

Over past decades strategies for improving access to drinking water in cities of the Global South have mainly focused on increasing coverage, while water quality has often been overlooked. This paper focuses on drinking water quality in the centralized water supply network of Lilongwe, the capital of Malawi. It shows how microbial contamination of drinking water is unequally distributed to consumers in low-income (unplanned areas) and higher-income neighbourhoods (planned areas). Microbial contamination and residual disinfectant concentration were measured in 170 water samples collected from in-house taps in high-income areas and from kiosks and water storage facilities in low-income areas between November 2014 and January 2015. Faecal contamination (Escherichia coli) was detected in 10% of the 40 samples collected from planned areas, in 59% of the 64 samples collected from kiosks in the unplanned areas and in 75% of the 32 samples of water stored at household level. Differences in water quality in planned and unplanned areas were found to be statistically significant at p &lt; 0.05. Finally, the paper shows how the inequalities in microbial contamination of drinking water are produced by decisions both on the development of the water supply infrastructure and on how this is operated and maintained.

Household water treatment and safe storage (HWTS) has been shown to improve drinking water quality and prevent disease. Efforts to scale up HWTS among vulnerable populations have been limited, partly due to an incomplete understanding of the socio-cultural influences on decision-making around uptake of HWTS. In-depth interviews were conducted with women in self-help groups in rural India who were exposed to a HWTS promotional campaign to investigate the influence of social networks on uptake of a household water filter. Results show discussion of the water filter amongst self-help group members, other peers, and family members allows social network members to share their opinions and purchasing intentions. This exposure is shown to shape individuals' opinions of the filter and establish purchasing norms within social networks. Within this cultural context, for high cost products like water filters, women needed to negotiate purchase with other household decision-makers. These results suggest that promoters of healthful durables like water filters must not only ensure product availability and financing, but also encourage platforms for discussion, recognize the socio-economic norms that develop around who adopts new technologies, and reach out to multiple actors in families and communities that influence individuals' behaviors and control household purchasing decisions.

Household water treatment (HWT) can reduce the diarrheal disease burden in populations without access to safe water. We evaluated five programs that distributed biosand, ceramic, or Sawyer filters in Haiti after the 2010 earthquake and cholera outbreak. We conducted household surveys and tested Escherichia coli and turbidity in stored household untreated and treated water in ∼50 randomly selected households from each program. Across programs, self-reported filter use ranged from 27 to 78%; confirmed use (participants with reported use who also showed the filter with water currently in it) ranged from 20 to 76%; and effective use (participants who used the filter to improve water quality to international guideline values) ranged from 0 to 54%. Overall, programs that more successfully met evaluation metrics: (1) distributed an effective technology; (2) provided safe storage; (3) required cash investment; (4) provided initial training; (5) provided follow-up; (6) provided supply-chain access; (7) targeted households relying on contaminated water sources; and, (8) had experience working in the local context. These findings, similar to results of previous research on HWT, suggest that well-implemented programs have the potential to result in sustained household filter use in Haiti.
