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.
This RURAL WATER SUPPLY DESIGN MANUAL is the first of three related volumes prepared for the use of prospective and actual owners, operators, managements, technical staff, consultants, government planners and contractors of small Level III and Level II water supply systems in the Philippines.

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.

This booklet seeks to suggest ways in which funds can be better used for making safe water available to the poor by illustrating how drilling costs can be reduced without compromising water quality, water quantity, or the productive life of the borehole.

Well rehabilitation is defined as restoring a well to its most efficient condition by various treatments or reconstruction methods (groundwater and wells). This continuing education unit discusses the causes of deteriorating well performance and methods, both traditional and more recently introduced methods.

This field note has been written for managers of water supply programmes and projects. It provides a step-by-step guide on the siting of drilled water wells. As a first step, the essential requirements for a simple groundwater model are set out, including some basic explanations to help the reader establish a sound understanding of hydrogeology.

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.
