GSWI visit report to South Sudan
Executive Summary and Recommendations
The Global Solar and Water Initiative team undertook a visit to South Sudan in order to assess selected existing solar pumping schemes, evaluate the feasibility to solarize water supply points in selected camps and raise awareness and solar technical expertise among WASH stakeholders in the country.
28 water supply schemes were visited in 7 locations: 26 in camps plus 2 solarised community systems in Pariang County.
Out of the 28 visited only 5 were running exclusively with generators.
Solar pumping has been extensively used in camps in South Sudan for the last years.
Security incidents in Bentiu POC camp hindered visits to 4 functional water supply points, 2 of which were being solarized.
The visit entailed collection of relevant data needed for full techno-economic analysis of the systems, in order to determine feasibility for solar pumping as well as gauge the design and performance of solarised schemes. Absence of basic data such as safe yields, water outputs (disaggregated in case of hybrid systems) or water levels made not possible to analyse all the visited water points, especially in Maban. Its absence put into question the basis for some of the existing solar designs.
Climatological and hydrogeological conditions in the locations visited were favourable, making the use of solar pumping a technically feasible solution for each and every borehole and surface scheme assessed
Wide support and prioritization given by some donors to solar solutions in South Sudan, together with a high solar irradiation through the year make the context good to use solar pumping in the country.
