Abstrak: Sewerage system is an important part of the urban infrastructure. The purpose of this study is to design a system configuration domestic sewerage and modify drainage systems for flushing discharge. This research use secondary data from relevant agencies, literature, and the results of previous study. Value of peak discharge (Qpeak) at inlet of WWTP 1 at the Bantarjati Village is 0.59 m3/sec with a diameter of 900 mm, while the Qpeak value at inlet the WWTP 2 at Mekarwangi Village is 1.42 m3/sec with a diameter of 1000 mm. The depth of excavation cultivated less than 6 m. Planned of Communal Septic Tank are 5 units in the Pakuan Mulyaharja, Ciluar, Balumbangjaya, and Kencana Village. Rainfall intensity calculation using Sherman Method. Micro drainage system is designed to supply discharge flushing. Flushing point as many as 53 points with range of flush discharge is 0.03 m3/sec. Drainage discharge range of 0.25 m3/sec. Shape of the channel using a rectangular channel with a width range of 0.43 m and 0.42 m high.
