This Water Business Kit is published jointly by IFC and Aquaya. It is intended to provide small and medium enterprises and entrepreneurs with a step-by-step guide to developing a water treatment and vending business in Kenya. Such businesses have been observed to serve customers in many parts of the world with high-quality, treated drinking water. These businesses represent the efforts of independent, local entrepreneurs to meet consumer demand for treated drinking water. Although the kit is based on research and information collected for Kenya, the guidance may be relevant to businesses in other countries.
