Jakarta develops sewage tunnel system with central government

Published: 09-Mar-2010

The Jakarta city administration is working with the central government to build a sewage tunnel system, which will channel household liquid waste to a plant that will recycle it into raw water.

Indonesia Governor Fauzi Bowo was reported stating that the government would use IDR3.8 trillion ($412.5 million) loan from the Japan International Cooperation Agency (JICA) for the initial construction of pipes and the plant. The city will contribute IDR700 billion ($76.3 million) of the total cost.

As per the government officials, the plant would turn liquid waste, including from septic tanks, kitchens and bathrooms into raw water before flushing it away into nearby rivers or dams. The city and the government would need to review a master plan of the first phase of the project, which is expected to start in the middle of 2011, be operational by 2020. In the first stage of the project, a team from the city and the government would construct the central zone project that would run from Setia Budi in Central Jakarta to a plant in North Jakarta. The plant’s location is not yet decided. The city is considering the options of an area near Pluit dam and Muara Angke, North Jakarta. The central zone would use a 1.8 meter diameter pipe from Setia Budi that would be pumped to the plant.

The next project would be the northwest zone, running from Gunung Sahari in Central Jakarta to Sunter in North Jakarta. The southwest zone would run from Palmerah to Kebon Jeruk in West Jakarta. The pilot project for the system was being applied in 11 cities, including Jakarta, Bandung in West Java, Medan in North Sumatra, Yogyakarta, Surakarta in Central Java, Banjarmasin in South Kalimantan and Denpasar in Bali.
