Byrraju Foundation: SWEET Water Project

In 2008, the Byrraju Foundation, an organization that provides self-sustaining services in Indian villages, was operating more than 50 water purification plants in the rural Andhra Pradesh region. However, almost five years after the launch of the foundation's SWEET Water Project, less than half of the residents of its targeted villages were drinking Byrraju water on a regular basis. The need for purified water was clear: studies showed that 80 percent of the illnesses in Andhra Pradesh were caused by contaminated water. In this case, students develop a marketing strategy to raise the profile of the SWEET initiative, and increase its penetration rates among villagers.
