Raw water source is an essential requirement for the survival of living things. Raw water requirements for Cimahi Subdistrict have increased from 115 L/sec (in 2018) to 310 L/sec (in 2038). The availability of raw water is only able to supply 84 L/sec, so there are still service areas that do not get clean water. The study of the availability of raw water is needed in order to meet water needs for water needs in 2038 with a planning period every 5 years. Based on the results of the analysis it was found that the dry discharge with duration and return period varied. The dry discharge used for the development of water resources is used R10-R20 years with a duration of 1 day, the dry discharge value obtained for the Cimahi River is 334 L/sec and for the Cibeureum River which is 275 L/sec. Dry discharge is used to plan the design of intake buildings according to the regulations for permit for taking water (Qizin <QR10). The raw water distribution system is one component in the development of a Drinking Water Supply System (SPAM). The approach to selecting the transmission path to be chosen is carried out using a weighting approach that contains various parameters. Based on the weighting of the three alternatives, the first alternative is obtained as the main path with a weighting value of 67.66%. This value is the largest value compared to alternatives two and three which have a value of 66% and 65.63%.
