Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.

These equipment packages have been devised by the Oxfam Public Health Engineering Team and others to help provide a reliable water supply, primarily for emergency situations such as in refugee camps and disaster-relief operations. The equipment is designed to be readily available, easily transported, simple to use, rapidly assembled, and fully self-contained, to provide an adequate water supply at moderate cost.
