- Abstract
Clean water supply in Galiukir Indigenous Village, Bali, is constrained by a large elevation difference, a long transmission pipeline, limited source yield, and inadequate existing pump head. This study develops a conceptual engineering design for a community-based high-head, low-flow water supply system serving 150 households or approximately 600 residents. Based on a domestic water consumption of 60 L/person/day and an assumed 1% water loss, the average design demand is 36.36 m3/day (0.421 L/s). The primary source yield of 0.27 L/s is insufficient to meet this demand, whereas the combined primary and secondary sources provide approximately 0.47 L/s or 40.61 m3/day. The hydraulic analysis was performed using the Darcy–Weisbach method for a PE100 DN/OD63 SDR11 PN16 transmission pipe with a length of approximately 910 m and a static elevation head of 136 m. At an upper conceptual flow of 0.50 L/s, the calculated major and minor head losses are approximately 1.55 m and 0.03 m, respectively, resulting in a steady-state total dynamic head of approximately 137.58 m. A 15% conceptual equipment-selection allowance gives a preliminary pump-selection head of approximately 158–160 m. Preliminary water-hammer screening indicates a peak pressure of approximately 14.21–14.33 bar, which remains below the nominal PN16 pressure class but requires further transient verification. The proposed configuration therefore adopts a variable-speed high-head multistage centrifugal pump supported by pressure monitoring, non-slam check valve, dry-run protection, air-release and washout valves, and reservoir-level control. The proposed design provides a technically quantified basis for subsequent detailed design, pump-curve verification, transient hydraulic analysis, and field commissioning.
