"Insya Allah (God willing), they will be completed and ready to be launched in March–April 2023," Jakarta's Assistant for Development and Environment, Afan Adriansyah Idris, said here on Thursday.
The projects, which are spread across five administrative areas, are expected to reduce flooding at some vulnerable points in the capital city during extreme weather spells.
The flood control infrastructure project has used the multi-year budget allocated by the provincial government, Idris informed. The budget of Rp1 trillion (around US$65.9 million) for the project is a loan from the central government, which was provided under the National Economic Recovery (PEN) program in 2021.
The nine polders are located in Muara Angke, Teluk Gong, Mangga Dua, Kelapa Gading, Pulomas, Marunda JGC, Green Garden, Kamal, and Tipala Pump - Adhyaksa Pump.
Meanwhile, the four water retention reservoirs are located in river overflow rooms (RLS) in Pondok Ranggon, Embung Wirajasa, Brigif, and Lebak Bulus.
The project for increasing the river capacity has covered the Kali Besar Sodetan Canal of Museum Bahari and the Ciliwung Hilir River in Pasar Baru, Central Jakarta.
In addition to the 942 flood-handling projects, two dams, namely Ciawi and Sukamahi in Bogor district, West Java, have also been prepared to reduce the flood potential in Jakarta.
President Joko Widodo inaugurated the two dry dams on December 23, 2022.
The head of state said that the two dams are expected to reduce flooding in Jakarta by about 30.6 percent, or help prevent inundation in 12 urban villages.
Ciawi Dam, whose construction began in 2016, can hold approximately 6.05 million cubic meters of water.
Meanwhile, Sukamahi Dam has the capacity to hold 1.7 million cubic meters of water.
