Each year, almost 1.5 million children around the world die from diarrheal and other diseases associated with unsafe water, inadequate sanitation and poor hygiene practices.
Our water, sanitation and hygiene (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 and toilets.
- Encourage healthy behaviors and strengthen supply chains.
- Improve the capacity of providers to deliver affordable, equitable and quality services to the poor.
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 private 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, to fund start-up projects, coordinate efforts to change key WASH behaviors, and to 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 opportunity, 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 also gather insights from private sector partners to:
- Develop business models for WASH providers that are valuable to the consumer.
- Create financial incentives for providers to adopt the re-defined model.
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.
- Water treatment: We improve access to clean water by promoting and distributing point-of-use household water treatment products.
- Sanitation: Our programs across 12 countries address urban and rural sanitation through community-led and market-based approaches.
- Hygiene: 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 and AIDS.

- Infusing Capital to Activate the Supply Chain for Sanitation Financing in Rural Bihar, India
In India, the estimated economic impact of diarrhea and inadequate sanitation amounts to an annual loss of US$38.5 billion. The state of Bihar has some of the poorest sanitation indicators in the country with 88% of rural households lacking access to toilet facilities. The vast majority of the population in Bihar (89%) live in rural areas, and of of these rural households, 68% belong to the poorest two wealth quintiles, where access to improved toilet facilities is the lowest.
