The Untapped Potential of Decentralized Solutions to Provide Safe, Sustainable Drinking Water at Large Scale
Dalberg Jan. 2017
This report argues that new approaches are needed to achieve the U.N. Sustainable Development Goal 6.1 by 2030. Through the analysis of 14 different small water enterprises, the report uncovers bottlenecks to scale and sustainability.
Field Assessment of a Novel Household-Based Water Filtration Device: A Randomised, Placebo-Controlled Trial in the Democratic Republic of Congo
Boisson, S. et al.
Household water treatment can improve the microbiological quality of water and may prevent diarrheal diseases, but bias can effect reported health impact in open trials. This randomised, controlled trial shows little evidence that a novel filtration device was protective against diarrhea.
This document examines several common myths associated with rural water supply, and provides evidence as to why they are not pragmatically true. It describes how enterprises can overcome these myths to provide sustainable and effective clean water supplies in rural regions.
End-User Preferences for and Performance of Competing POU Water Treatment Technologies among the Rural Poor of Kenya
Albert, J., Luoto, J., and Levine, D.
Environmental Science & Technology
We do not understand the factors that influence preference for and adoption of household point-of-use water treatment technologies targeted at vulnerable populations. In this study of 400 rural subsistence farm households in Kenya, relative end-user preference was measured across three products.
Alternatives for Safe Water Provision in Urban and Peri-Urban Slums
Journal of Water and Health
Due to lack of resources in developing countries, water treatment systems tend to be decentralized and often water treatment occurs at the household level. This paper explores the potential of developing community level systems by engaging the community and government.
Cost of Delivering Water Services in Rural Areas and Small Towns in Ghana
Nyarko K. B., Dwumfour-Asare, B., Appiah-Effah, E. and Moriarty, P.
IRC International Water and Sanitation Centre
The life-cycle costs approach quantifies the cost of delivering water services in rural areas and small towns in Ghana: average annual cost for small town piped water systems ranges from US$ 10 to 14 per capita per year while that for water point sources is about US$ 4 per capita per year
Estimating the Scope of Household Water Treatment in Low- and Medium-Income Countries
Rosa, G., Clasen, T.
The American Society of Tropical Medicine and Hygiene
About 33% of low and medium income countries are using household water treatment to improve water quality and prevent disease. Boiling the water is the dominant method. African and rural households are least likely to use treatment despite having poor access to improved water sources.
Sick Water? The Central Role of Wastewater Management in Sustainable Development
As urban populations grow, and slums flourish, there is an increase in volume of waste water that needs to be managed with improved infrastructures and systems. Waste-water tends to contaminate clean water, and as a result there is a threat in reduction of safe water availability.
Gridlines: Partnering for Water in Cote d’Ivoire. Public-Private Infrastructure Advisory Facility
Marin, P., Ouayoro, E., and Verspyck, R.
Public-Private Infrastructure Advisory Facility
The Public-Private Partnership (PPP) for the national water utility of Côte d’Ivoire demonstrates an African success story shows that a pragmatic partnership between a committed government and an efficient private operator can produce tangible and sustained benefits for the population.
Solar Disinfection of Water Reduces Diarrhoeal Disease: An Update
Conroy, R., Meegan, M., Joyce, T., McGuigan, K., and Barnes, J.
Archives of Disease in Childhood
Children drinking solar disinfected water had a significantly lower risk of severe diarrhoeal disease over two weekly follow up visits. Solar disinfection is effective in vivo as a free, low technology, point of consumption method of improving water quality.
Microbiological Quality and Metal Levels in Wells and Boreholes Water in Some Peri-Urban Communities in Kumasi, Ghana
Obiri-Danso, K., Adjel, B., Stanley, K. N., Jones, K.
African Journal of Environmental Science and Technology; Vol 3(1), 59-66
This study assessed the quality of water in boreholes and wells in Kumasi, Ghana. The overall quality of water in boreholes was better than wells, however some of the shallower ones were of poor quality. Quality also declines during the wet season.
