Zone 1 sewerage area is one of the most prioritized areas out of 15 zones in Jakarta. The WWTP site will take place in Pluit, and will adopt Anoxic-Anaerobic-Aerobic (A2O) process, combined with membrane bio-reactor system (MBR) due to its compact size to fit the limited site. Construction period of WWTP will take 54 months, including 18 months period for Defect Notification Period (DNP) and Operation and Maintenance (O&M), including O&M training for operator.

While, for sewer networks, total of 14.3 km (in Area 1-1) and 24.9 km (in Area 1-2) will be constructed under the project. The construction will last for 48 months, including 12 months period for DNP.
