Design of water supply and fire protection system in a low income five storey apartment of Andalas University has been conducted based on Indonesian National Standard (SNI) regulation No.03-7065-2005, that the building which has more than 500 inhabitants or more than 1.500 visitors, should prepare plumbing system design. The University of Andalas Student Rental Building is a residential building of five floors. In this water supply plan the water source is supplied from the Unand’s water treatment plant. The water supply system uses a roof tank system with a combination of gravity flow and booster pump. The water supply tank consists of the bottom tank and the upper tank with capacities of 74 m³ dan 4,5 m³, respectively. The booster pump meets the critical pressure on the 3rd floor up to the 5th floor with 5,44 m head. Class II fire prevention systems use hydrant and sprinkler systems with automatic wet-type upright pipes. The distribution pipes use PVC pipes (1/2  - 1 1/4) inches, while the hydrants and sprinkler pipes use Black Steel (1-4) inch pipe.
