REPUBLIC OF SIERRA LEONE - FEASIBILITY STUDY FOR MANUAL DRILLING - MAPPING OF FAVOURABLE ZONES

In the framework of its programme focused in supporting the application of low cost techniques of manual drilling in Africa, UNICEF promoted a study having as main purpose the analysys of the existing information at national level for in order to have an initial knowledge of areas where environmental and hydrogeological situation could make hand drilling techniques a potentially suitable low cost and sustainable solution to increase the availability of water for the population. The study has been carried out through the analysis wit support of GIS systems of a set of data collected from public source of data (mainly web) and the collection of data available in different institutions at national level by a local consultant.
The present study aims to give a general idea and it is extend to the whole country; the results of this study must be used to target specific ares where more detailed analysis are required in order to have a detailed idea of the best strategy and location to support manual drilling. | »

The 2019 RWSN directory of rural water supply services, tariffs, management models and lifecycle costs 2019 Edition [ENGLISH]

The rural water supply sector is undergoing a period of change. In response to the challenges of achieving universal access to safe, affordable drinking water and sustaining those services, there has been increasing innovation in different types of rural water service models.

This Directory is intended to show the growing range of management options. Some are novel interventions that are still being piloted, others have been established for a decade or more.

Also includes: Handpump Statistics 2019 (from WPDx data from Sub-Saharan Africa and Asia-Pacific)

What’s Working, Where, and for How Long A 2016 Water Point Update to the RWSN (2009) statistics

• An average of 78% of water points are functional across the 11 countries analyzed.

• The high failure rates early after installation are troubling: almost 15% after one year and 25% of water points are non-functional by their fourth year after installation. This indicates widespread problems with poor quality water point installation, due to a range of problems that may include professionalism and skills around contracts, construction and supervision; borehole siting; lack of quality control of hardware; or lack of post-construction monitoring and problem resolution.

• Handpumps are often singled out as technology that fails, but analysis of other water point types show similar functionality levels, and that tens of thousands of handpumps are providing a service

This poster was peer-reviewed and presented at the 7th RWSN Forum in Abidjan, Cote'Ivoire 2016.

Effective Joint Sector Reviews for Water, Sanitation and Hygiene (WASH) A Study and Guidance - 2016

This is the first consolidated and referenced multicountry study of Water or Water, Sanitation and Hygiene (WASH) Joint Sector Reviews (JSRs). The study report and associated Learning Note and Poster provide an understanding of JSR processes and practical guidance on how to introduce and improve them. The study sets out a methodology in the form of visual checklists to reflect and take stock of WASH JSR processes. This could also form the foundation for subsequent cross-country comparisons of the JSR process.

The publications provide an analysis of JSRs as well as practical guidance on how to introduce and effectively manage them. The initial focus of the work was on JSRs in fragile states. However, the contested definitions of a fragile state, arbitrary thresholds as well as the realization that there are common issues with respect to JSRs in nonfragile countries led to a widening of the scope of countries studied. Notably, all countries included are considerably donor dependant for WASH. The study considered 25 countries, and found that between 2001 and 2015, WASH JSRs had taken place in 19 of them.
