Drinking water is a basic requirement of human life, so its availability is very important. Along with population growth, the demand for drinking water will increase. Gedebage Sub-district consists of 4 villages that have an area of 955 hectares and are located at an altitude of 750 m above sea level. In the supply of drinking water, only about 20% of the population is served by piping networks sourced from Badak Singa IPA WTP owned by PDAM Tirtawening Bandung and there is often a continuity problem regarding the availability of water to reaches customers. In an effort to fulfill long-term needs, it is necessary to increase the supply of drinking water for Gedebage District, one of which is by designing a drinking water distribution network. As an effort to emphasize the loss of water to facilitate supervision, it is also necessary to establish a District Meter Area (DMA). The projected water demand for the next 20 years is 67.38 liters / second. So that the capacity of the Badak Singa IPA WTP cannot cover this need. Therefore, a water source from the Cisangkuy River is used for which water treatment will be carried out at Cikalong WTP. In designing the distribution channel there are 3 alternative distribution channels, namely using branch, circular patterns, and simulated combinations using EPANET 2.0 software. Then the path selection is done using the Simple Additive Weighting (SAW) method so that the selected path is obtained, namely the circular path. In addition, the formation of 6 DMA based on selected distribution lines is also carried out to facilitate the control of water loss.
