Jakarta Sewerage System is a centralized wastewater management project, which aims to improve the condition of DKI Jakarta's wastewater management which only covers 4% of the whole area with a BOD pollution level of 84 mg/l (KPPIP, 2019). In this project, the DKI Jakarta area is divided into 14 zones and there are several zones planned to have WWTPs which only serve each region in the zone, one of which is zone 6. The Jakarta Sewerage System WWTP 6 will be built in the remaining area of the Duri Kosambi Faecal Sludge Treatment Plant (FSTP) land, and the treatment plan will be integrated with the Duri Kosambi FSTP. The form of integration of WWTP and FSTP is that the sludge produced by WWTP will be transferred to the FSTP, then the supernatant from FSTP will be transferred to WWTP. The planning period of Zone 6 WWTP is 30 years starting from 2020 to 2050, which is divided into 4 construction phases according to the construction phase of the wastewater pipeline network. The treatment capacity of Zone 6 WWTP is obtained based on the consumption of clean water and rainwater infiltration discharge, the WWTP treatment capacity obtained in 2050 is 237,737 m3/day. With a processing capacity of 237,737 m3/day and limited land, Zone 6 WWTP is planned to use processing units that can save land use. In primary processing, the units planned are continuous fine screen, equalization and fine mesh screen. The results of primary processing show the value of the BOD/COD ratio is 0.75 so the secondary treatment plan used is biological processing.
