This dissertation investigates the commercial viability of point-of-use (POU) water treatment systems (solar treatment, physical treatment and chemical treatment) in lower income settings. Six factors that have helped POU projects approach commercial viability are highlighted, including refining and improving product positioning, leveraging existing health awareness, offering an array of POU options, adapting business practices, finding alternative models of viability, and focusing on key product improvements.
