Household and community water treatment in developing countries

About this Research Topic

Providing access to safe drinking water is one of the most effective means to improve public health. Unsafe water continues to be a major cause of millions of diarrhoeal deaths occurring annually, mostly in children in developing countries. Despite major efforts to deliver safe, piped, community water to the world’s population, safe water supply at community level may not be available to all people in the near future. The situation requires that all possible approaches must be tried to mitigate the problem by maximizing the control at the level of the households for their own water security. The household water treatment and safe storage, promoted globally by the WHO to reduce the global burden of water-borne diseases, is one such approach to facilitate the achievement of the UN Sustainable Development Goal of drinking water for all by 2030. The current research topic will focus on the different household treatment methods and their effectiveness in providing good quality drinking water.

While microbial contamination is prevalent all over the world, many communities are presently facing the problem of chemical contamination of their groundwater sources which are their only source of drinking water. Arsenic, fluoride, iron and nitrates are the commonly reported pollutant in groundwater. Of the several technologies that are available for household water treatment, some appear to be the most widespread and promising for further development. These include household sand filters, coagulation-flocculation with natural coagulants, chemical disinfection, solar disinfection, filtration through ceramic filters and boiling which are used for treating microbial contamination. Various physicochemical methods are being developed for the removal of inorganic contaminants at household or community level.

The main goal of this Research Topic is to showcase the studies and various technologies used in household and community water treatment. These include studies primarily focusing on the removal of microbial contaminants as well as chemical pollutants. The focus will also be given on the potential application of technologies that are not currently in use for household water treatment. This Research Topic welcomes Original Research, Review articles, Mini Review, and Perspective articles with a focus on themes including, but not limited to:
• Technologies for microbiological purification at household/community level
• Methods for removal of chemical pollutants such as As, F, Fe and nitrates
• Use of combined methods for household water treatment
• Case studies on the application of household water treatment technologies
• Studies on the sustainability of the household/community water treatment systems
• Quality considerations of source water
• Management/decision-making systems for water supply in developing countries
• Contamination and safe storage of treated water.


Keywords: Household water treatment, biosand filter, solar disinfection, ceramic filters, microbiological purifiers
