Building B Mixed Income Housing planned in the Kampung Tambun Rengas area, Cakung District, East Jakarta City is intended for the people of the area who come from heterogeneous economic levels. With the planning of this building, it is expected to improve the welfare of the community and aims to create social interaction between residents and reduce social disparities and marginalization over time. Therefore, the infrastructure can meet the needs of various types of people, the urgency of proper sanitation aspects must be met, so a building plumbing system is designed which includes a clean water supply system, a waste water collection system, a vent system, a rainwater utilization system, and a fire fighting system. The scope of the plumbing system to be designed in the form of piping is a building that has 11 floors with 10 floors designated as residential floors. These residential floors have 12 rooms per floor with 2 types of typical floors. The first typical floor is on floors 2, 4, 5, 7, 8, 10, and 11 and the second typical floor is on floors 3, 6, and 9. The shaft used is a centralized shaft in the middle of the building. In the design, several alternative choices are made that pay attention to several aspects, namely construction methods, operations, economics, user safety, Green Building, and regulation. The method used is SAW or Simple Additive Weighting. Based on the alternative selection method using SAW, the selected alternative is alternative 2 with the use of a centralized shaft. Buildings that have 1090 occupants have clean water needs that range from 40.32 m3 per day and produce wastewater that ranges from 32.256 m3 per day, therefore design and management by the building needs to be done so that sanitary conditions in the building can be maintained. The clean water system designed in the form of a bottom and roof tank system, in the lower tank, water collection is carried out from the water supply managed by PAM JAYA and then pumped to the top of the building to be collected and flowed to the occupants of the building. For the wastewater plumbing system is distinguished for graywater and blackwater. Greywater will be flowed to the STP or Site Treatment Plant to be treated along with rainwater so that it can be used as flushing water in the toilet, while blackwater is treated in anaerobic treatment tanks whose effluent from processing in accordance with these standards will be flowed to the nearest water body, and sludge from processing will be siphoned periodically. Vent piping, storm water harvesting, and fire hydrant piping are also designed as disaster prevention measures.
