This case provides an overview of the nonprofit organization PATH and its Safe Water Project-a five-year effort launched in late 2006 with $17 million in funding from the global development unit of the Bill and Melinda Gates Foundation. The purpose of the grant was to evaluate to what extent market-based approaches could help accelerate the widespread adoption and sustained use of household water treatment and safe storage products by low-income populations. Through a portfolio of field-based pilots, PATH intended to experiment with different sales and distribution strategies to improve consumer access to safe water solutions, such as water filters and chlorine-based water purification tablets. It also planned to test different pricing and consumer financing models to address the affordability of these products. However, extensive market research revealed another problem-few products in the space were both effective and designed specifically to meet the unique needs and preferences of these consumers. Accordingly, PATH applied for and was awarded $7 million in additional grant funding from the Gates Foundation to design a water filter product that would meet high standards of efficacy, be desirable-or aspirational-to low income consumers, and work effectively within the rural conditions where the majority of the poor resided. The PATH team would accomplish this through a process that the organization called user-centered design.

The purpose of the grant was to evaluate to what extent market-based approaches could help accelerate the widespread adoption and sustained use of household water treatment and safe storage products by low-income populations. One of the team's primary objectives was to investigate sales and distribution challenges in this space. By conducting a portfolio of field-based pilots, the team hoped to test different models for improving customer access to these safe water products in an effort to identify scalable, sustainable, and replicable solutions. Although specific results varied across the pilots, which spanned India, Vietnam, Cambodia, and Kenya, they collectively gave rise to series of important sales and distribution insights.

This case provides an overview of the nonprofit organization PATH and its Safe Water Project-a five-year effort launched in late 2006 with $17 million in funding from the global development unit of the Bill and Melinda Gates Foundation. The purpose of the grant was to evaluate to what extent market-based approaches could help accelerate the widespread adoption and sustained use of household water treatment and safe storage products by low-income populations. One of the key objectives of this effort was to explore how the private sector could help make HWTS products more affordable. By conducting a portfolio of field-based pilots in collaboration with commercial partners, the PATH team sought to better understand the effect of different pricing, consumer financing, and subsidy models on demand within low-income population in developing countries. Over several years, the Safe Water Project team experimented with different affordability models, including microfinance loans for water filters and a layaway program. Although specific results varied across the pilots, which spanned India, Cambodia, and Kenya, they collectively gave rise to series of important insights about the affordability of HWTS products.
