Freshwater scarcity is projected to become a major global issue, with the construction industry currently responsible for approximately 30% of worldwide freshwater consump- tion throughout the life cycle of civil infrastructure. As a result, water management and its potential to alleviate water scarcity while enhancing the sustainability of con- crete require greater attention in scientific research and practical application. Existing studies indicate that non-po- table water, such as treated domestic wastewater, could be viable for producing structurally sound concrete in the construction sector.
