Abstract

Water scarcity and uneven distribution of freshwater resources remain major challenges. As a higher education institution, Brawijaya University holds strategic potential to pioneer sustainable water management practices aligned with the United Nations Sustainable Development Goal (SDG) 6: Clean Water and Sanitation. This study investigates the feasibility and impact of implementing rainwater harvesting systems in the campus environment as a means to enhance water conservation, promote water reuse, and reduce dependency on external water supply. The research employs a mixed-method approach involving hydrological assessment of rainfall patterns, estimation of potential harvested volumes, and evaluation of reuse pathways such as sanitation, and landscape irrigation. The socio-environmental benefits are analyzed through the lens of water security, climate resilience, and contribution to SDG targets, particularly increase water-use efficiency and protect water-related ecosystems. Rainwater harvesting can cover a proportion of non-potable water demand, while reducing stormwater runoff and enhancing local aquifer recharge. The study positions rainwater harvesting not only as a technical solution but also as a model of sustainable campus management that integrates conservation, education, and community awareness. Ultimately, this research provides a framework for universities to contribute actively toward achieving global sustainability goals through localized water management innovations.
