This article focuses on point-of-use drinking water treatment and safe storage options, which can accelerate the health gains associated with improved water until the longer-term goal of universal access to piped, treated water is achieved. It summarizes five of the most common options for household water treatment: chlorination, filtration (biosand and ceramic), solar disinfection, combined filtration/chlorination, and combined flocculation/chlorination. It describes implementation strategies for each and identifies implementing organizations and the successes, challenges, and obstacles they have encountered in their projects. It also considers sources of funding and the potential for large-scale distribution and sustainability of each option, and proposes future research and implementation goals. A consistent evaluation scheme is used for each of the household water treatment and safe storage (HWTS) options discussed: 1. Does the HWTS option remove or inactivate viral, bacterial, and parasitic pathogens in water in a laboratory setting?; 2. In the field, is the HWTS option acceptable, can it be used correctly, and does it reduce disease among users?; and 3. Is the HWTS option feasible at a large scale?
