PATH and the Safe Water Project: Making Safe Water Products More Affordable

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.
