This compact 20-page review of safe water solutions describes smart business thrusts such as water kiosks, chlorination by micro-entrepreneurs, locally-produced pot filters and industrially manufactured water filters. Equally, with numerous cases, it discusses how to remove constraints to upscaling: viability, scalability, consumer acceptance and ability to reach the poor. A larger study will be published in early-2011
