The safe water social venture (SWSV) projects commenced in South Sudan in January 2004. If this is of interest, the link below contains the origin story. The South Sudanese projects had to shut down in 2016 due to the civil war there. The resilient team members were able to restart the projects in Uganda (TEDx talk in 2nd link below). We are presently in the process of securing Gold Standard for the Global Goals carbon offsets for the Ugandan projects (due to the avoided need to boil water). These will allow the Ugandan projects to scale up their impact and to restart the projects in South Sudan (hopefully next year)
