Sustainable Water Extraction at UNS Campus

Universitas Sebelas Maret (UNS) has developed a Drinking Water Supply System (SPAM) on campus to provide safe drinking water for all members of the university community. Raw water is drawn from deep wells on campus and treated using Ultrafiltration (UF) technology. This process is designed to ensure that the water meets drinking water quality standards, and the SPAM system is certified by SNI.

All water used across the UNS campus area is obtained from groundwater wells through a sustainable pumping and monitoring system that minimizes environmental impact and ensures long-term aquifer stability. The SPAM system at the UNS campus is equipped with a solar power plant (PLTS) with a capacity of 2.5 liters per second to support sustainable operations. The treated water is then distributed through pipes to water fountains and dispensers at various strategic locations on campus, allowing the university community to access drinking water directly and thereby reducing their reliance on bottled water.

To ensure sustainable water extraction, UNS applies responsible water extraction practices. The flow from the deep wells is regularly monitored to prevent over-extraction, and the pumping system is designed to be energy-efficient. In this way, the campus can utilize its internal water sources sustainably, in line with the principles of responsible water extraction and monitoring.

The development of the SPAM at UNS demonstrates sustainable water extraction practices, involving the responsible use of internal water sources and the utilization of renewable energy for system operation. Moreover, the program is part of UNS Green Campus initiatives, serving as an educational platform for students and staff on the importance of sustainable water management and responsible use of water resources.
