Jakarta, ID – Coordinating Minister for Infrastructure and Regional Development Agus Harimurti Yudhoyono (AHY) stated that the construction of the North Coast of Jakarta’s protective infrastructure (Giant Sea Wall) Phase A is being carried out, as the northern coastal communities are constantly threatened by tidal flooding caused by land subsidence and the high levels of groundwater extraction.
“We are striving to save human lives, the lives of our fellow citizens who have inhabited this area for a long time. As the Coordinating Minister for Infrastructure, I would like to affirm, together with the Minister of Public Works and the team, that future developments are always oriented towards efforts to improve safety and the quality of life for the community," said Coordinating Minister AHY in Jakarta, Wednesday (6/11/2024).
Coordinating Minister AHY made this statement while inspecting the construction work of the North Coast of Jakarta’s protective infrastructure (Giant Sea Wall) Phase A, accompanied by the Minister of Public Works, Dody Hanggodo, and the Deputy Minister of Public Works, Diana Kusumastuti.
Therefore, the government, through the Public Works Ministry and relevant stakeholders, continues to strive to implement the concept of environmental remediation to mitigate the impact of tidal flooding. This concept can be achieved by providing clean water through the construction of Karian Regional Water Supply System (SPAM), Jatiluhur I SPAM, and Djuanda/Jatiluhur II SPAM.
Furthermore, water quality improvement at river estuaries (sanitation) is being addressed through the Jakarta Sewerage System project, and flood control is being managed by constructing the Ancol Sentiong Pump Station and coastal embankments integrated with the polder system in the downstream area. Additionally, the Ciawi and Sukamahi dams are being built for flood control in the upstream area. The normalisation of the Ciliwung River and the construction of the Ciliwung River diversion channel are also being carried out to control flooding in the midstream area.
“We are striving to ensure a clean water supply that can support the needs of the community. Therefore, we are ensuring that Jatiluhur Water Supply System (SPAM) can provide a supply of approximately 3,200 litres per second, and that Karian SPAM in Banten can also soon be operational to increase the clean water supply. This way, the community can reduce groundwater extraction activities,” added Coordinating Minister AHY.
Support from Various Parties Required
Meanwhile, Public Works Minister Dody Hanggodo explained that in the efforts to tackle tidal flooding and land subsidence, the Public Works Ministry also requires support from various parties, including local governments and the community. This is particularly important in ensuring that the needs of all citizens are met fairly and equitably.
“We must collaborate with local governments, both city and provincial. They have the authority over the area. Then, the Public Works Ministry will prepare the clean water supply infrastructure. Further cooperation with local governments is needed to build the networks or pipelines to each household,” explained Minister Dody.
“Similarly, we will also treat wastewater from the community to ensure that sanitation in Jakarta is healthier and better maintained,” added Minister Dody.
The construction of the North Coast of Jakarta’s protective infrastructure Phase A consists of building coastal and river estuary embankments stretching 46 kilometres (km). In 2019, the Public Works Ministry completed the construction of 12.66 km of embankments. This project was then continued by the Public Works Ministry and the Jakarta Provincial Government in 2020, covering an additional length of 33.54 km.
The coastal embankments that have been constructed include the Kamal Muara – Dadap Embankment, which includes Fishermen’s Access and Pump House as well as Retention Basin, Kalibaru Embankment, Kalibaru Retention Basin, Cilincing Retention Basin, and Cakung Drain Embankment.
Meanwhile, if land subsidence continues, the construction of Phase B of the Giant Sea Wall will be carried out. This Phase B Sea Wall is projected to reduce the flood-prone area by 112,000 m² and decrease potential losses by up to Rp600 trillion.
“Currently, a feasibility study is being conducted on the design and financing aspects of the Giant Sea Wall project in Jakarta,” concluded Minister Dody.
