While urbanisation and industrialisation have brought about economic growth and improved living standards, their impact on the environment and natural resources such as water has been controversial. Utilities have always been the main player in ensuring the provision of safe and adequate water supply to meet the demands of both the population and industries. But the combined pressures of rapid population, economic growth, and climate change are making this an increasingly difficult task to fulfill. The sustainability of our water resources in the near future is at risk. Over the past few years, the global industrial sector has been identified as the second largest water consumer and hence, can contribute significantly to water sustainability efforts. This contribution includes the implementation of effective water and wastewater treatment technologies as well as being open to innovative technical solutions and strategies that can increase the efficient use or reuse of water in industrial processes. The challenges in both availability of water, which calls for greater water reuse, and the quality of the water discharge, which necessitates more stringent water treatment strategies, have been recognised. However, the interdependency of water and energy still requires more attention, and strategies for recovering energy throughout processes will be of high importance. This theme focuses on water-intensive industries such as oil and gas, food and beverage (F&B), and mining.
