Scaling up solar powered water supply systems: a review of experiences

Over the past few years, UNICEF has been exploring new and innovative approaches to water supply, placing an emphasis on systems which are affordable, scalable, environmentally sustainable and climate smart. Solar
powered water systems have the potential to meet all of these criteria. The systems can also help provide a higher quality service to multiple communities through the use of small piped water schemes and therefore play a key role in helping to accelerate the achievement of the Sustainable Development Goal (SDG) on water and sanitation.

The Solar Powered Water System assessment was carried out in four countries; Nigeria, Mauritania, Uganda and Myanmar and was supported by a global UNICEF country office survey and literature review. The assessment aims to take stock of the progress made so far, particularly in terms of programming and the long-term sustainability of systems. It will also provide key lessons to consider when moving forward. | »

Resilience in Groundwater Supply Systems: Integrating Resource Based Approaches with Agency, Behaviour and Choice (RIGSS) Final Report

Focusing on groundwater supplies, RIGSS explores how the interplay between environmental resources, social systems and behavioural choices affects the use of groundwater supplies. It focuses on the case of Nigeria as a means of piloting research approaches and exploring wider conceptual issues. The approach combines perspectives on the interplay of factors influencing choice and behaviour including: the nature of the hydrogeological resource, the perceptions of identified actors, actors’ engagement with news and information resources, socio--‐economic and political factors, psychological factors and the role of coping and survival strategies in the face of shocks and anticipated events. | »

Water Quality Testing Study, Port Harcourt, Nigeria World Bank Contract#7167983

This water quality study was conducted to help inform pending infrastructure investment programs in the city of Port Harcourt, Nigeria, in an environment in which very little a priori information was available. It was also intended to build technical capacity within two local institutions. These were the Port Harcourt Water Corporation (PHWC), a para-statal water service provider, and the Rivers State Ministry of Water Resources and Rural Development (MWRRD), its oversight authority within the state government. The study employs an innovative method for sample selection that relies on widely available remote sensed data, geographic information system (GIS) tools and smartphone-based navigation technology. | »

Manual Drilling Compendium 2015 RWSN Publication 2015-2

Manual drilling refers to several drilling methods that rely on human energy to construct a borehole and complete a water supply. The various techniques can be used in areas where formations are quite soft and groundwater is relatively shallow.

Manual drilling can provide safe drinking water. The equipment can easily be transported to remote, or difficult to serve populations which would otherwise be left behind. The lower costs compared to machine drilling are appreciated by households, businesses and governments. Manual drilling also provides local employment.

Manual drilling methods are being used to provide water for drinking and other domestic needs at least 36 countries around the world. In some places, manual drilling methods are well established.

The compendium provides a useful overview for those wishing to further examine the impacts and challenges of manual drilling, and, more importantly, improve practices on the ground. It is hoped that the document will spur others to undertake fur-ther studies as well as research to document stories and analyse the promotion, uptake and use of manually drilled boreholes. In addition, the compendium should also enable those promoting manual drilling to realise that they are certainly not alone in their endeavours! | »

Handpump Standardisation in Sub-Saharan Africa: Seeking a Champion RWSN Publication 2015-1

Handpump standardisation is the formal or informal mechanism that governs the varieties of community handpumps used within a particular country. In a handful of countries this also includes stand-ard handpump designs. With over a million handpumps in sub-Saharan Africa and new installations every day, handpump standardisation is still vital for the policy and practices of governments and implementing organisations. While rural water practitioners are polarised about the future of formal standardisation, the extent of informal standardisation is of significant importance to the sustain-ability of handpumps across the continent. Of the thirty-five countries in sub-Saharan using handpumps, formal standardisation has emerged in fifteen through regulations (nine countries), and endorsements (six countries). However in the remaining countries, informal standardisation determines what handpumps are installed where, either through recommendations (fourteen countries), or de facto standardisation (six countries). | »
