Executive Summary

Currently, some estimated 884 million people worldwide lack access to improved water supply and 2.6 billion people lack access to improved sanitation (WHO/UNICEF 2010). An estimated 2 million people die every year due to diarrheal diseases, most of them children less than 5 years of age. The most affected are populations in developing countries, living in extreme conditions of poverty, normally peri-urban dwellers or rural inhabitants. Among the main problems responsible for this situation are: lack of priority given to the sector, lack of financial resources, lack of sustainability of water supply and sanitation services, poor hygiene behaviours, and inadequate sanitation in public places including hospitals, health centres and schools. Providing access to sufficient quantities of safe water, the provision of facilities for a sanitary disposal of excreta, and introducing sound hygiene behaviours are of capital importance to reduce the burden of disease caused by these risk factors (WHO 2010).


In most developing countries, perhaps most easily discernible in the poorest countries, unclean water and poor sanitation exposes billion of men, women and children to a plethora of diseases that debilitate them and greatly reduce their productivity. These diseases even hasten the death of those with compromised immune systems such as small children, the malnourished and HIV/AIDS patients. Despite advances in science, engineering and legal frameworks, the majority of the wastewater from piped sewerage systems in the world is released into the environment without adequate treatment (UJANG & HENZE 2006). The same is true for most pit latrines and sludge management systems. Only a small percentage of global wastewater is treated using advanced sanitation facilities, mainly in developed countries. Faecal pathogens are transferred to the waterborne sewage system through flush toilets or latrines, and these may subsequently contaminate surface waters and groundwater (PRUESS-UESTUEN & CORVALAN 2006) (see also water pollution).

Prevalence of Waterborne Diseases

As a result, the majority of the world’s population is still exposed to waterborne diseases, and the quality of water sources has been rapidly degraded, particularly in poor developing countries (UJANG & HENZE 2006). UNDP (2006) describes unclean water as an immeasurable greater threat to human security than violent conflict. In addition to unclean water, lack of sanitation and poor hygiene are responsible for the transmission of diarrhoea, cholera, typhoid and several parasitic infections (UN 2005).

Moreover, WHO (1997) shows that the incidence of these diseases and others linked to poor hygiene and sanitation e.g. round worm, whip worm, guinea worm, and schistosomiasis is highest among the poor, especially school-aged children. These diseases have a strong negative impact on the health and nutrition of children and their learning capacities, and contribute to significant absences from school (NOKES & BUNDY 1993). Most significant, however is the persistence and wide distribution of diarrhoeal disease throughout the developing world.

Effects of Water Related Diseases

Water related diseases cost 443 million school days each year, and children in poor health suffer from reduced cognitive potential. This hurts their prospects for future earnings and makes continuing poverty more likely (BORKOWSKI 2006). About 3.5 billion people in the world are infected with helminth worm parasites (CHAN 1997; CAPRON 2004; MIGUEL & KREMER 2004; UNESCO 2006). These parasitic helminth infections often lead to severe consequences such as cognitive impairment, massive dysentery, anaemia and death of around 9400 people every year (WHO 2004). In Sub-Saharan Africa, schistosomiasis kills more than 200,000 people every year (UTZINGER & KEISER 2004). Infectious diarrhoea can be caused by bacteria (e.g. E. coli, shigellosis), viruses (e.g. norovirus, rotavirus), and protozoan parasites (e.g. amoebiasis, cryptosporidiosis) (OECD 2007). Acute diarrhoea, as occurs in cholera, if left untreated can cause death within a day or less and has devastating impact on children (UNICEF 2006) (see also economic issues).

Due to the interconnectedness between water, sanitation, health and poverty, lack of safe water supply and proper sanitation has much wider impacts than on just health alone. Large-scale death and poor health are not only matters in its own right but also act as a brake on economic development (WAGSTAFF & CLAESON 2004). The interconnectedness and the impacts that unsafe water and inadequate sanitation have on human health and general well-being makes it absolutely necessary to deal with all these issues or concerns together. Water quality and sanitation are irrevocably intertwined. Poor sanitation leads to water contamination. In many parts of the world, the main source of water contamination is due to sewage and human waste (MOE & RHEINGANS 2006). Unsafe water and inadequate sanitation disproportional impacts the poor in particular. About 2/3 of people without access to a protected water source (piped water or a protected well) live on less than US$2 a day (BORKOWSKI 2006). Adequate water supplies improve the prospects of new livelihood activities, which are otherwise denied, and are often key step out of poverty (UNESCO 2006).

The relationship between the health status and the sanitation coverage can be seen in the figure below:

UNDP (2006) emphasises that clean water and proper sanitation can make or brake human development. Furthermore, the combination of poverty, poor health and lack of hygiene means that children from unserved homes, miss school more frequently than those whose families do benefit from improved drinking water and sanitation services. The resulting lack of education and social development further marginalises the children and reduces their future chances of self-improvement (WHO/UNICEF 2005) (see also hygiene frameworks and approaches).

The problem with disposing of menstrual waste into pit latrines is that it causes the pits to fill up faster. The excreta in the pit decompose and decrease in volume, while the non-biodegradable components of menstrual waste accumulate and do not break down. Furthermore, once the sludge has been removed from the pit latrine, if it is to be used in agriculture, any waste that has not completely decomposed such as menstrual pads must be removed before the sludge can be composted or applied to farmland. The cost to remove, screen, and dispose of menstrual management products from pit latrine sludge is high and not accounted for.

Diarrhoeal diseases are a leading cause of mortality and morbidity, especially among young children in developing countries. While many of the infectious agents associated with diarrhoeal disease are potentially waterborne, the evidence for reducing diarrhoea in settings where it is endemic by improving the microbiological quality of drinking water has been equivocal. The aim of the present study is to assess the effectiveness of interventions to improve water quality for preventing diarrhoea.

In many countries, knowledge about the potential for harm from health-care wastes has now become more prominent to governments, medical practitioners and civil society. The indiscriminate and erratic handling and disposal of waste within health-care facilities is now widely recognized as a source of avoidable infection, and is synonymous with public perception of poor standards of health care. Water pollution and inadequate wastewater treatment pose important risks to health.

Currently, little or no management of healthcare wastes occurs in small-scale facilities in developing countries. Training and infrastructure are minimal. Common practice in urban areas is to dispose of healthcare waste along with the general solid waste or, in peri-urban and rural areas, to bury waste, without treatment. In some cities small hospitals may incinerate waste in dedicated on-site incinerators, but often fail to operate them properly. Unwanted pharmaceuticals and chemicals may be dumped into the local sanitation outlet, be it a sewage system, septic tank or latrine. The contamination of water sources represents serious health risks.

Child stunting and anemia are intractable public health problems in developing countries and have profound short- and long-term consequences. The Sanitation Hygiene Infant Nutrition Efficacy (SHINE) trial is motivated by the premise that environmental enteric dysfunction (EED) is a major underlying cause of both stunting and anemia, that chronic inflammation is the central characteristic of EED mediating these adverse effects, and that EED is primarily caused by high fecal ingestion due to living in conditions of poor water, sanitation, and hygiene (WASH).

The resulting WASH intervention comprises material inputs and behavior change communication to promote stool disposal, handwashing with soap, water treatment, protected exploratory play, and hygienic infant feeding. Nurture and disgust were found to be key motivators, and are used as emotional triggers. The concept of a safe play space for young children was particularly novel, and families were eager to implement this after learning about the risks of unprotected exploratory play.

This review looks at the policy environment for diarrhoea control in three African countries, in order to glean lessons learnt about what more we can do to address this problem. While solutions are available to prevent and treat diarrhoea, the political will and health prioritisation are still lacking to make these solutions widely available to those who need them most. To accelerate progress in cutting mortality from diarrhoea, global and national decision-makers need to take urgent action.

Water quality, sanitation, handwashing and nutritional interventions can independently reduce enteric infections and growth faltering. There is little evidence that directly compares the effects of these individual and combined interventions on diarrhoea and growth when delivered to infants and young children. The objective of the WASH Benefits study is to help fill this knowledge gap.

Poor sanitation remains a major public health concern linked to several important health outcomes; emerging evidence indicates a link to childhood stunting. In India over half of the population defecates in the open; the prevalence of stunting remains very high. Recently published data on levels of stunting in 112 districts of India provide an opportunity to explore the relationship between levels of open defecation and stunting within this population.

Open defecation is exceptionally widespread in India, a country with puzzlingly high rates of child stunting. This paper reports a randomized controlled trial of a village-level sanitation program implemented in one district by the government of Maharashtra. The program caused a large but plausible average increase in child height, which is an important marker of human capital. The results demonstrate sanitation externalities: an effect even on children in households that did not adopt latrines.

In Bangladesh diarrhoeal disease and respiratory infections contribute significantly to morbidity and mortality. Handwashing with soap reduces the risk of infection; however, handwashing rates in infrastructure-restricted settings remain low. Handwashing stations - a dedicated, convenient location where both soap and water are available for handwashing - are associated with improved handwashing practices. The aim of this study was to identify a locally feasible and acceptable handwashing station that enabled frequent handwashing for two subsequent randomized trials testing the health effects of this behaviour.

Diarrhea, pneumonia, and birth complications are the top three killers of children under age 5 worldwide. Diarrhea is also a leading cause of undernutrition in this age group, and one-third to one-half of all child mortality cases are linked to undernutrition. If mothers and other caregivers used basic hygiene practices and had better access to safe water and adequate sanitation this could greatly reduce under-5 deaths and improve child nutrition.
