The project at hand is designed to contribute to the overall aim to sustainably improve the wellbeing and health conditions of the poorest and most vulnerable communities in South Sudan. More specifically the project proposes to increase the beneficiaries’ access to sufficient and clean drinking water, reduce water shortage during dry seasons, and increase their access to sanitation facilities. In addition the project focuses on the improvement of the communities’ capacity to sustainably operate and manage its water resources, water infrastructures and sanitation facilities. This is directly related to the overall improvement of the beneficiaries’ health by means of adopting safe hygiene and sanitation practices. Several training components accompany the construction measures to address the needs and to strengthen the beneficiaries capacities. The training measures refer to 1.) the creation of Village Water Committees, which will regulate and manage the village water system and its consumption, 2.) on-the-job trainings for local craftsmen and technicians in order to be able to provide simple repair and maintenance work as well as the 3.) training of Village Hygiene Promoters, who sensitize the village communities in hygiene and sanitation aspects. Overall the project implementation strongly applies a participatory approach to create ownership among the beneficiaries and to ensure the continuation of the initiated project in the communities.
