Campus Water Supply and Monitoring System

Caraga State University (CSU) operates a centralized water supply system, ensuring reliable access to clean water across its academic, residential, and administrative facilities. The system utilizes a mechanical power pump that extracts groundwater daily to meet the campus’s total water requirements. The pumped water is stored in a cylindrical tank measuring 10 meters in height and 5 meters in radius, with a storage capacity of approximately 785 cubic meters.

From this storage tank, water is distributed through an extensive underground piping network that has served the campus for about two decades. The General Services Office (GSO) regularly oversees system maintenance, monitors pump performance, and tracks estimated discharge volumes to effectively manage water consumption.

Based on daily pumping operations, CSU’s estimated annual water volume reaches about 286,000 cubic meters under full operation. Accounting for periods of low attendance, holidays, and class suspensions, the adjusted annual consumption is approximately 258,000 cubic meters. These figures are based on inbound extracted water in 2024, monitored via tank operation and regular system inspections, which serve as the university’s baseline data for tracking consumption and planning efficiency.
