Even though solar water pumping is ready for mainstreaming and has started to take off in some parts of the world, its benefits remain largely unknown to communities, governments, and development institutions. 

To address this knowledge gap, the World Bank has developed an accessible and interactive Knowledge Base on Solar Water Pumping. This online repository aims to raise awareness about the technology and provide resources that help incorporate it into operations. Currently, the repository contains more than 260 resources from all regions where the World Bank works, and covers a broad range of issues from technological change to institutional setup.
