Each year, 842,000 people around the world die from diarrheal and other diseases associated with unsafe water, inadequate sanitation, unsafe fecal sludge management and poor hygiene practices. Good water, sanitation and hygiene (WASH) practices are also a significant contributor to improving nutritional results, enabling quality care in clinics and hospitals, and preventing other diseases.
Our WASH programs improve the health of low-income families in the developing world by increasing access to and use of WASH products and services, such as household water treatment, soap, and toilets.
We leverage the expertise and resources of the public and private sectors to maximize health impact in WASH programming:
- The private sector is a powerful way to reach low-income households, especially as they access products and services every day through local providers and channels. We engage with actors at multiple levels in the private sector to develop viable WASH business models that better respond to consumer needs and preferences through strengthened supply and demand.
- We also work in close collaboration with the public sector, including in-country governments and international donors and policy makers; create a policy environment that is conducive to market growth for WASH; fund start-up projects; coordinate efforts to change key WASH behaviors; and ensure that those who have less ability to pay are able to access products and services.
Our consumers are at the center of our solutions. We use formative research to identify WASH products and services that consumers want and need, as well as their ability and motivation to adopt new behaviors. These insights are used to develop marketing strategies that promote behavior change and ensure WASH products and services are appropriately priced, promoted and placed.
We have promoted household water treatment for more than a decade. To date, we have prevented almost 30 million cases of diarrhea and sold enough water treatment products to treat more than 1 billion liters of water.
In recognition of the different transmission routes that infections can follow, we launched a comprehensive WASH strategy in 2011 and currently have household water treatment programs in 30 countries, handwashing programs in four countries and sanitation programs in 12 countries. This work is further supported by our global network of experts in social marketing and franchising.
Household water treatment: We improve access to clean water by promoting and distributing point-of-use household water treatment products.
Sanitation and fecal sludge management
Community-led total sanitation programs: In areas where open defecation is the norm, we empower communities to change unhealthy behaviors and to adopt basic sanitation.
Market-based sanitation: Through a market development approach, we identify market failures, their root causes, and then determine the most appropriate interventions needed to improve demand and supply for a healthy sanitation market.
Handwashing: We work to increase the practice of handwashing with soap at key times among caregivers of children under five, primary school children and vulnerable populations, including people living with HIV/AIDS.
- 2016 Rural Sanitation and Hygiene Behavioral Study Vietnam
In December 2016, PSI Vietnam conducted a behavioral study among 1,200 rural households in Tien Giang and Dong Thap provinces to assess PSI’s sanitation social marketing program progress and to inform future improvements in coverage and sanitation as well as hygiene behaviors. This study highlights the continuing need for improved sanitation and hand-washing with soap practices among rural families in Vietnam, and identified factors that need to be addressed in order to improve sanitation and hand-washing practices.
