Solar pumping for rural water supply: life-cycle costs from eight countries 40th WEDC International Conference

Although interest in solar water pumping has been steadily growing, misconceptions persist about the applicability and cost-effectiveness of such systems in remote settings. The primary barrier to wide scale adoption of solar water pumping is that policy makers and practitioners at the local, national and international levels lack valid and transparent information on performance in a broad range of contexts and of the full life-cycle costs. In an attempt to fill this information gap, this paper presents upfront and recurring costs from 85 rural solar water pumping schemes of various sizes that have been designed, constructed and supported by Water Mission in eight countries. The average life-cycle costs associated with the reviewed schemes were within and on the lower end of IRC WASHCost benchmark ranges for both piped water schemes and boreholes fitted with handpumps. These findings indicate solar pumping is a viable and cost-effective intervention for rural water supply. | »

Assessing Community Management of Water Sources in Rural Tanzania Masters Thesis Academic Year 2017

This research study investigates the communal management of water points in a village in rural Tanzania. Following an explorative and people-centred approach, the study provides local in-depth views on how water is accessed and how water sources are managed. The focus is on the barriers people face when bearing the responsibility to manage their water sources.

The study shows that water access and its management are strongly influenced by gendered division of labour, communal power structures, cultural traditions, and daily habits. Instead of understanding water as a bare natural resource with an economic value, this study indicates that water is also a social fact. | »

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.

Domestic Rainwater Harvesting: Tanzania Field Study Report 2009

This report presents the key findings of a study of the domestic rainwater harvesting (DRWH) sub-sector in Tanzania. The principle purpose of the study was to assess the potential of rainwater harvesting (RWH) for domestic use in Tanzania, and equally to collect appropriate background information necessary to evaluate the potential commercialization of the EnterpriseWorks/Vita flexible membrane water tank. Essentially, the study sought to assess the preferred product attributes and technical parameters needed to stimulate demand for the product and evaluate the potential for its commercialization.
