Abstract

Climate-change-driven water security has been declining rapidly in Lesotho, Africa, in recent years. This study provides a scenario for improvement of a gravity water distribution system, in which modifications to the existing tap system are proposed. The tap system was modeled in EPANET, a water distribution network solver. New pipe diameters were calculated to accommodate both the peak demand of the school campus and the basic daily water amount of 30 L per person for the village. Due to climate change, however, there is not enough water anymore to meet the required demands of local Basotho people, and they may have to migrate to areas where water is available. This case study serves as an example of a problem that will occur more and more in the world as climate change continues.
