Climate change and rising global temperatures cause water scarcity and increased water demand. It is vital to ensure the sustainability of existing water resources, to decrease irrigation water consumption, and to harvest rainwater. Hasan Kalyoncu University, one of the UI GreenMetric members, is located in Gaziantep, an adjacent city to the Mediterranean basin with an annual rain of 558 mm. The campus has a 49% green area, which consumes approximately 70% of the water. This study aims to optimize irrigation water by developing a mathematical model for establishing the sustainable water management of the university. The total green area is categorized and indexed to determine the need for irrigation water needs. The optimization of irrigation water has a considerable contribution to sustainable water management. The best solution is to choose climate-compatible plants and change the plant pattern without reducing green areas. It was calculated that decreasing the grass by 25%, increasing the olive tree by 20%, and expanding the area of various plants by 12% reduce the campus’s potential maximum irrigation water requirement by 7%. The model is a core solution and may contribute to the sustainable development of Gaziantep if enhanced and applied to parks in the city.
