Jakarta Provincial Government along with Coordinating Ministry for Economic Affairs and developer will hold the groundbreaking of Giant Sea Wall (GSW) phase A construction on Thursday (10/9). The groundbreaking is in form of strengthening the 32-kilometer long dike on the northern coast of Jakarta.

The GSW phase A construction is ready and must be completed within three years

“The GSW phase A construction is ready and must be completed within three years,” asserted Jakarta Vice Governor Basuki T Purnama, Tuesday (10/7).

When Basuki went to South Korea some time ago, he had proposed for the GSW construction on the northern coast of Jakarta to be reviewed.

“Not all parts of the GSW, just its outside part (phase B). The inner part doesn’t need to be reviewed,” he stated.

Basuki explained that GSW construction needs to be reviewed because the phase B is worried might be a waste pond of 13 rivers in Jakarta. Moreover, the northern coast of Jakarta does not have high tidal wave that could ‘flush’ the sediment in the dike.

“The phase A is like Pantai Indah Kapuk. For phase B, it needs to be reviewed. That could finish until 2030,” he told.

For information, GSW construction on Jakarta Bay waters is divided into three phases. The first phase is strengthening the coastline of Jakarta, including dike strengthening and pipe station installation. Its total investment is Rp 1.9 billion.

The second phase is the construction of outer sea wall and sea reclamation as wide as 1,250-4,000 hectares in the period of 2018-2022. This phase will also include construction of highway from Tangerang and Bekasi, pipe station, sluice, pipelines relocation, and mangrove forest restoration at an estimated cost of Rp 4.8 billion.

And the third phase is the construction of outer sea wall in the east side of Jakarta. However, it is still cannot be determined yet whether the sea wall is required or not since land subsidence in east area is still relatively slow and the main rivers are still flowing freely.
