Roughing filtration is a simple, efficient and chemical free water treatment method for turbidity removal; it can be used as a pre-treatment method prior to slow sand filters or disinfection with chlorine. The main disadvantage of roughing filtration for use in emergency situations is that it uses gravel as a filter medium. Gravel may be unavailable or difficult to transport because of its …
This report is the final output of the ‘Value for Money Study in Global Sanitation Fund Programmes’, hereafter ‘the VFM-GSF project’, funded by the Water and Sanitation Supply Collaborative Council (WSSCC)/Global Sanitation Fund (GSF).
The stated objectives of the project were threefold:

Globally, at least two billion people use a drinking water source contaminated with faeces1. As result of microbial contamination with faeces, it poses the greatest risk to drinking-water safety. In 2010, the UN General Assembly explicitly recognized the human right to water and sanitation. Everyone has the right to sufficient, continuous, safe, acceptable, physically accessible, and affordable …
Unhygienic environments place children at risk of death. Some 1.5 million deaths of under-fives a year are caused by diarrhoea, deaths which can be avoided if diarrhoea in this age group is prevented or appropriately treated. Diarrhoea also stunts children’s physical and intellectual growth and is a huge cost factor. Overall, 2.2 million people died because of diarrhoea in 2002. Hygiene …
Reliable and cost-effective monitoring of rural water supply infrastructure has long been hampered by the geographical curse of dispersed and low-income populations, and weak institutional performance. Recent advances in monitoring technology combined with mobile network expansion into rural areas has created an opportunity to bypass these seemingly intractable challenges. Mobile-enhanced …
This film depicts on how unsafe water can affect health of children and their ability to be strong and fit and play football. While one of them is aware about the importance of clean drinking water, he also insists other friends not compromise with the quality of drinking water.
Theory-based interventions can enhance people's safe water consumption, but the sustainability of these interventions and the mechanisms of maintenance remain unclear. We investigated these questions based on an extended theory of planned behaviour. Seven hundred and ten (445 analysed) randomly selected households participated in two cluster-randomised controlled trials in Bangladesh. Study 1 …

Nepal has relatively high inland water resources and is geographically diverse. It is topographically divided into three regions: high Himalaya, middle Hill, and low land Terai. Due to such diversity, the drinking water services are different in all regions. In Himalayas and Hilly regions, water supply systems are mainly through gravity flow whereas hand-pumps and deep boring are in Terai. As per …
This evidence synthesis, commissioned by the Humanitarian Evidence Programme and carried out by a team from the Civil and Environmental Engineering Department of Tufts University, identifies, synthesizes and evaluates existing evidence of the impacts of water, sanitation and hygiene (WASH) interventions in disease outbreaks in 51 humanitarian contexts in 19 low and middle-income countries (LMICs).
Water quality monitoring is important for identifying public health risks and ensuring water safety. However, even when water sources are tested, many institutions struggle to access data for immediate action or long-term decision-making. We analyzed water testing structures among 26 regulated water suppliers and public health surveillance agencies across six African countries and identified …
WASH markets are likely to be affected by a crisis. It can create disruption of both supply of and access to WASH-related goods and services. Both need to be considered and addressed by humanitarian responses to people’s needs. But if humanitarian agencies do not consider markets, interventions can accidentally harm these markets and the whole population depending on them. In the case of weak …
