T The availability of clean water in high-rise buildings is very supportive of the activities of building users in it, so a good pipe installation planning is needed. High-rise buildings are buildings with a minimum of four floors which are commonly used for hotel apartments, offices and shopping centers (malls). The BRIAN Hotel in the Wahid Hasyim area of ​​Jakarta is currently under construction. One of the important things in a high-rise building is a planning system for the installation of clean water distribution pipes, installation of dirty water pipes and installation of waste water pipes called the plumbing system. This plan begins with a field visit to obtain the data needed to determine the location of the pipe installation, then an isometric drawing is made to make it easier to calculate the diameter of the pipe used and calculate the volume of the Ground Water Reservoir (GWR) and the volume of the roof tank. Based on the results of the pipe installation planning, the results are not too far away, this is still considered reasonable.
