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.
RWSN, with support of the Water and Sanitation Programme of the World Bank (WSP-AF) is supporting the formation of a Nigerian Drillers Association. This report provides an overview of the Nigerian drilling environment and sets out the first stage of the process of establishing the association.

Many people living in coastal regions rely on shallow groundwater for their water supply. Seawater flooding after a severe storm or tsunami can damage wells and contaminate the groundwater. This technical note provides advice for rehabilitating wells in such circumstances. It should be used in conjunction with Technical Note 1 which provides general information about rehabilitating wells after a disaster.

The website provides many excellent publications on various topics on rural development, particularly on hand drilled wells. This section presents an overview of the scale and type of hand drilling activity being undertaken in selected countries and the organisations involved.
As the quality of water can be seriously affected by a disaster or an emergency, it is best practice to disinfect all emergency water supplies. The most common way of disinfecting is with chlorine. This technical note explains why disinfection is important, why chlorine is used, how it works, how to test for its presence and where and when to test.
