In response to the growing need for sustainable and healthy practices, many universities have made significant strides in providing free drinking water to students, staff, and visitors. Universitas Airlangga (UNAIR) in Indonesia is a prime example. The university has implemented a comprehensive system to ensure access to safe drinking water across its campuses. Strategically placed water dispensers and ready-to-drink water taps are available at key locations, including the Joint Lecture Building, university lake, prayer rooms, and library, making it convenient for the entire campus community and visitors to stay hydrated.
