Jakarta to evaluate giant sea wall development

Jakarta, Ekuatorial – DKI Jakarta government would evaluated its planning to cooperate with South Korea to construct its great sea wall project, said a senior official on Monday (22/9), in Jakarta.

The decision came after DKI Jakarta Deputy Governor, Basuki “Ahok” Tjahaja Purnama, visited Saemangeum Sea Wall, the world’s longest man-dyke, in South Korea, last week.

Ahok had agreed to re-evaluate the cooperation with South Korea after learning that both areas have different contour. South Korea, which is much higher than the sea level, is suitable for the open-close system of the dyke. On the contrary, Jakarta is lower than the sea level, if using the same system it would risk polluted sea water runs through and contaminate the dyke.

Andi Baso Mappapoleonro, Head of DKI Jakarta Planning Development Agency, said to deal with the waste water, the project would best to use pumps rather than the system.

Furthermore, he said that the system could flood coastal areas and endanger fishermen’s lives. The study case revealed three Korean fishermen were killed by the tides after they opened the dyke in early operation.

“[The] great sea wall in Jakarta is much suitable to adapt the concept in Rotterdam, Netherlands,” he said adding that they would still be cooperating with South Koreans on technical development.

The Jakarta Giant Sea Wall runs from Jakarta-Bekasi border in the east to the Jakarta-Tangerang border in the west. The 200 trillion rupiah (US$ 16 billion) project is designed to deal with flooding as a result of sea level rise, to clean river water before runs through the ocean, clean water supply, and coastal reclamation.

It has been constructed during Fauzi Bowo’s administration in cooperation with Deltares, a Netherlands consultant company. It should start its development in 2020 and end in 2030.

The project, which is now known also as National Capital Integrated Coastal Development, has been under the coordinating ministry of economic involving ministry of public works.

The project comprise of three phases, starting with reclamation, wall development, and the giant sea wall along with man-made lake development and huge pumps. The current government had agreed to speed up to the last phase.

Nevertheless, there are some doubts on the project, especially on its environmental strategic assessment from the ministry of environment as it will affected coastal ecosystems of Bekasi, Tangerang, and Tanjung Priok harbor, also Muara Karang power plant in North Jakarta. Ekuatorial Team
