This article examines the potential of space science technology for water infrastructure (WI) management. It defines space technology in detail, and when South Africa (SA) started using it as a tool. To explain the context, the different types of orbits, altitudes, and functions of satellites are given, as well as the challenges that satellites encounter in orbit, including the quantity and sizes of orbital debris also known as space junk. The article articulates the international and local challenges to WI and further introduces space technology as a tool that can assist to overcome the challenges. Legislation governing the application of space technology in SA is discussed and the different satellites owned by the various space agencies of Africa are outlined. A discussion on how space technology has boosted the economies and employment in Africa and South Africa is provided. How the various applications of the technology, such as remote sensing (RS), Earth observation (Eo), Geo-Information sciences, navigation, communication, safety, and security can assist WI management are discussed. Details about the involvement of various African and SA universities and colleges in space science programmes that benefit the communities are explained. Also outlined are some experiments performed on the International Space Station (ISS) that benefit the Earth and that could be useful to WI management.
