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.

Long Term Sustainability of Outer Space Activities (LTSOSA) was adopted during the UNCOPUOS Session in June 2019. It consists of 21 guidelines in four (4) categories, namely: policy and regulatory framework of outer space activities; safety of outer space operations; international cooperation, capacity building and awareness; and technical research and development. The LTSOSA is in line with the definition of Space Security which relates to guaranteed access to Space and the ability to freely exploit space for various purposes. Space Security cover both: safety, sustainability and the security of the space system and actors. While Human Security is an approach to assist the Member States in identifying and addressing widespread and cross-cutting challenges to the survival, livelihood and dignity of their people. It calls for people-centered, comprehensive, context-specific and prevention-oriented responses that strengthen the protection and empowerment of all people. This article will be focused on analyzing and elaborating three (3) main issues: The correlation among LTSOSA, Space Security and Human Security; The Contributions of LTSOSA and Space Security toward the achievement of Human Security’s Objectives; and Legal and Regulatory Framework of LTSOSA, Space Security and Human Security.
