The Republic of Indonesia, the world's fourth most populous country, continues to achieve stable economic growth and ranks the first in ASEAN region in terms of economic scale, whereas the coverage rate of sewerage system remains at around 12% in the capital city of Jakarta, which has a population of over 10 million. Under these circumstances, the water environment in the capital city needs further improvement urgently and therefore the development of sewerage systems including sewer pipelines and wastewater treatment facilities are necessitated accordingly. Jakarta has unveiled the " Project for Capacity Development of Wastewater Sector through reviewing the Wastewater Management Master Plan in DKI Jakarta ", which divides the entire Jakarta area into 15 treatment zones and plans to improve the living environment by installing sewerage systems in stages.
This contract is to construct a wastewater treatment plant in Zone 1, which is known as the area of a high population density and many commercial facilities such as shopping malls, as part of Jakarta Sewerage Development Project. Due to site space constraints, the anaerobic anoxic aerobic activated sludge process + membrane bioreactor (MBR) will be adapted for a wastewater treatment plant with a capacity of 240,000 m3/day (equivalent population: 1.2 million), which saves space and allows for efficient wastewater treatment. This contract will be undertaken on a unit price contract basis as a designed by the Minister of Public Works and Housing of Indonesia, incorporating Remote Controlled Pneumatic Caisson Method and other Japanese advanced technologies throughout, to realize high-quality technology transfers.
