About Us WIN-SA is a network of organisations focusing on improving knowledge sharing in the water and sanitation sector, targeting local government and other decision makers. It is being set up as a network of organisations (both government and non-government) in the water services sector. These organisations all have a vested interest in information and knowledge generation and dissemination to local government. They are trying to ensure the body of knowledge in the sector is well managed, readily accessible and applicable, and will lead to improved decision-making and performance in the area of water and sanitation.
