Water is fundamental to our health, our way of life and our environment. It underpins growth in population and our economy—and these are critical to South Australia’s future prosperity. High quality science and monitoring of our State’s natural water resources is central to the work that we do. This will ensure we have a better understanding of our surface and groundwater resources so that there is sustainable allocation of water between communities, industry and the environment. Department for Water scientific and technical staff continue to expand their knowledge of our water resources through undertaking investigations, technical reviews and resource modelling.
