  • Challenges to the Commercial Viability of Point-Of-Use (POU) Water Treatment Systems in Low-Income Settings John Harris Disserta
    Challenges to the Commercial Viability of Point-of-Use (POU) Water Treatment Systems in Low-Income Settings John Harris Dissertation submitted in partial fulfillment of an: MSc in Water Science Policy and Management School of Geography and the Environment Oxford University September 2, 2005 Abstract Point-of-use (POU) water treatment systems have been put forward in recent years as low-cost, scalable, and effective solutions to the significant challenge of providing potable drinking water in lower income settings. In spite of their usefulness, however, levels of adoption and continued use remain low. Recently, several projects have turned to a commercial approach in order to make the products more widely available. This trend seeks to position POU products alongside other health-related products which have been delivered in part by a commercial approach, such as condoms or bed-nets. Drawing upon semi-structured interviews with key industry experts, this research argues that these initial projects have failed to boost significantly adoption rates. Reasons for this failure are explored. Nevertheless, the pursuit of commercial viability presents a promising strategy by which to promote POU products’ adoption and sustained use. Strategies that have helped POU projects achieve partial commercial viability thus far, and may be useful in formulating strategies for POU projects seeking commercial viability in the future, are developed and explored. While projects promoting POU products have to date been unsuccessful in achieving commercial viability, should they do so in the future, these products, in conjunction with a commercial approach, have the opportunity to change the paradigm for the provision of potable water in lower income settings.

ABSTRACT AND KEY FINDINGS This is a report of the evaluation of the Zambia Safe Water Systems program conducted by The Mwengu Social and Health Research Centre and the Johns Hopkins Bloomberg School of Public Health. The intent of this study was to assess how the Safe Water System was being used in areas where marketing and distribution had focused. Sites were selected on a nationwide basis using distribution information from Society for Family Health (SFH), Population Services Inter- national’s (PSI) local affiliate, who ran the social marketing program for CLORIN. A sample size of 1319 households was used, stratifying for type of marketing and household characteristics. For each of these households interviews were carried out among heads of households, primary water caretakers, primary child caretakers and information gathered on children in the household under age five.

  • Monitoring Effective Use of Household Water Treatment and Safe Storage Technologies in Ethiopia and Ghana by Matthew M
    Monitoring Effective Use of Household Water Treatment and Safe Storage Technologies in Ethiopia and Ghana by Matthew M. Stevenson 1. Introduction Household water treatment and storage (HWTS) technologies dissemination is scaling-up to reach out to the almost 900 million people without access to improved water supply (JMP, 2008). Successful scale-up requires monitoring and evaluation (M&E) of behavioral indicators to achieve safe water and improved health. This paper presents a consistent framework for the operational monitoring of the behavioral indicator “Effective Use” as of a set of eight HWTS technologies including dilute bleach solution, Aquatabs, solar disinfection (SODIS), cloth filters, the ceramic pot filter, the biosand filter, PUR and associated safe storage practices. “Effective Use” is defined as the proper operation of HWTS technologies in the home, as instructed by the implementing agency, resulting in the production and storage of clean water in order to limit exposure to a variety of waterborne diseases. A framework for operational monitoring of Effective Use at the household is developed in Chapter 3. The framework consists of two systems of independent checks on Effective Use in the home. Monitoring Observations specific to each technology, comprised of the five categories of Treatment, Safe Storage, Maintenance, Replacement Period, and Physical Inspection are laid forth. A set of Water Quality Monitoring methods is used to confirm the Monitoring Observations. Field methods for measuring turbidity, residual free available chlorine, and E.coli as an indicator of microbiological water quality are described in Chapter 2 that require minimal training, time, or equipment and are cost- effective (US $3.60 for a complete round of household tests).

Correspondence to: Ubydul Haque. Department of Biostatistics and Epidemiology, University of North Texas Health Science Center, Fort Worth, TX, USA. Email: [email protected]. Abstract: Worldwide, there are an estimated 2.3 billion people living in water-scarce and stressed areas. The water in these areas may contain harmful pathogens, such as bacteria, that can have a negative effect on human health. Poor sanitation, lack of hygiene, contaminated water sources, and the overall poor quality of drinking water leads to disease and death amongst people of all ages in underdeveloped and developing countries. In order to better the health of these communities and the quality of water, affordable water treatment technologies that can reduce harmful contamination to potable water standards must continue to be developed. The purpose of this study is to review the currently available techniques, such as solar water disinfection (SODIS), chlorination, ceramic and biosand water filtration and slow sand filtration, that can be utilized in developing countries.

  • Experiences with Ceramic Pot Water Filtration Systems in Uganda: a Case Study of the Health and Social Impacts of a Market-Based Approach
    Experiences with ceramic pot water filtration systems in Uganda: A case study of the health and social impacts of a market-based approach by Fantasia Williams A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science / Master of Landscape Architecture (School for Environment and Sustainability) in the University of Michigan May 2020 Thesis Committee: Assistant Professor of Practice, Jose F. Alfaro, PhD Professor, Environmental Health Sciences, Marie S. O'Neill, PhD Abstract: Nearly half of the developing world lacks access to improved sanitation, and millions of individuals lack access to improved drinking water. Following trends of the rest of the developing world, diarrheal diseases are the number one cause of death among children under five years old in Uganda. Among all age groups, diarrhea can still be found among the top ten causes of death, continuously securing the sixth spot over the past ten years. In response, SPOUTS of Water, a Ugandan based NGO, began manufacturing and selling ceramic pot filters as an effective and affordable method of water treatment. Across various locations and over time, evidence has demonstrated that improving water and sanitation conditions can prevent a significant portion of diarrheal disease. The primary objective of this cross-sectional study is to investigate if the usage of the Purifaaya filter in two Ugandan communities is associated with a reduced prevalence of diarrheal disease. After adjustments for the total number of persons in a household, location (urban vs rural), water source, and toilet type, the study found that there was an association between filter use and the reduction in reported diarrheal disease.
