Abstract

The installation of clean water is a very important building component to support the activities of residents in the building, because this component is a provider of water needs for building occupants to carry out bathing, washing, cooking activities, and so on. In planning a clean water installation system, four criteria must be met, namely: Sufficient quantity, Hygienic, Optimal technical, and Economical. Research has been carried out by modeling clean water installation to determine the type of pipe that most effectively meets the clean water installation criteria to be applied to residential buildings. The method used in this study is the modeling of a clean water pipe installation with 3 types of pipes (Polyvinyl Chloride (PVC), Poly Propylene Random (PPR), and Galvanis), measuring the flow rate and water pressure by simulating all the open sanitation points and simulating one of the open sanitation points in turn, then performing calculation of Implementation of Budget Plan for pipe installation. The results showed that the flow rate and pressure readings on the PVC pipe installation experienced an increase in the flow rate of 0.00624 m3 and the pressure decreased by 3.015 psi, the PPR pipe installation experienced an increase in the flow rate of 0.0104 m3 and the pressure decreased by 3.86 psi, while the galvanized pipe installation experienced an increase in the flow rate of 0.029 m3 and the pressure decreased by 3,285 psi. The cost needed to make a PVC pipe installation is Rp. 336,635, to make a PPR pipe installation of Rp. 514,583, and to install a Galvanized pipe of Rp. 538,370. Based on the results of testing and analysis of the implementation budget, it can be concluded that the most effective type of pipe to be used in the installation of clean water pipes in residential homes is PVC pipe.
