Self-supply, where households invest to develop their own easily-accessible water supplies, is identified as an alternative service delivery model that is potentially complementary to more highly subsidised community-level provision. The approach is widespread in Ethiopia with family wells bringing additional benefits that are in line with wider government objectives, such as supporting small-scale irrigation. However, two recent studies show the current performance of traditional or family wells to be far below potential with most sources providing unsafe water in the absence of adequate protection.

This report by UNEP provides an overview of current major water quality contaminants and the human activities that affect water quality. It details the impacts that poor water quality has on the environment, human health, and vulnerable communities, and quantifies the economic costs of poor water quality. Il also offers insights into specific solutions available to address water quality problems.

Hand dug wells may need repairing, cleaning and disinfecting after inundation by flood- or seawater or after long periods of insufficient maintenance. This Technical Brief elaborates on the process of repairing; cleaning and disinfecting hand dug wells and also discusses the OXFAM kits, which can be used for this purpose.

The Ministry of Local Government and Housing, in consultation and collaboration with key stakeholders, has formulated National Guidelines to improve the utilisation of water resources on a sustainable basis through effective O&M. These guidelines are based on the experiences of implementation of rural water supply projects in Zambia.

This field manual brings together knowledge of the technique of upgrading simple shallow wells. The simple technique of upgrading simple shallow wells has been investigated and tested by staff of the Blair Research Laboratory and subsequently by staff of the Mvuramanzi Trust for many years. It is now well established in many areas of Zimbabwe.

Desalination has become one of the main sources of water in most of the countries in the Middle East and North Africa (MENA) region. All MENA countries lie in the Sunbelt region and have the space needed by solar technologies. Success in implementing solar technologies in desalination depends on the progress made or to be made to economically convert solar energy into electrical and thermal energies.

This paper describes the use of solar thermally driven stand-alone desalination systems adapted to remote areas based on membrane distillation. The aim is to develop systems for a capacity ranging from 0.2 to 20 m3/day. Technical simplicity, long maintenance-free operation periods and high quality output are the important parameters that will enable successful application of the systems.
