The first phase of dredging works to restore the capacity of existing drainage canals commenced in November 2013, with the commencement of four physical works contracts at various project locations (out of a total of eight works contracts supported by the project). What is the status of the project implementation? About 42.2 km of embankments/walls are expected to be rehabilitated or constructed within these floodways, canals and retention basins. The 11 floodways / canals are estimated to have a total length of 67.5 km, while the four retention basins estimated to cover a total area of 65.1 hectares. Sections of the following floodways, channels and retention ponds will be rehabilitated with the support of the JUFMP/JEDI project: Ciliwung-Gunung Sahari Floodway, Waduk Melati, Cengkareng Floodway, Lower Sunter Floodway, Cideng Thamrin Drain, Sentiong Sunter Drain, Waduk (Pond) Sunter Utara, Waduk Sunter Selatan, Waduk Sunter Timur III, Tanjungan Drain, Lower Angke Drain, Upper Sunter Floodway, West Banjir (Flood) Canal, Grogol Sekretaris Drain, Pakin – Kali Besar – Jelakeng Drain, Krukut Cideng Drain and Krukut Lama Drain. Which floodways and basins will be dredged? Fifteen priority sections of floodways, canals and water retention ponds in Jakarta have been identified to be restored with the support of this project. Comprehensive hydraulic modeling of recent major flood incidences has shown that the extent and impact of these floods would have been significantly less had the city’s flood infrastructure been operating at their full design capacities. Studies have shown that the restoration of these floodways, canals and water retention ponds is the most beneficial short term step to help alleviate the impact of flooding in Jakarta. Over the years, sedimentation and solid waste accumulation have significantly reduced the water carrying and retention capacities of Jakarta’s existing flood management infrastructure. How will JUFMP/JEDI help mitigate floods in Jakarta? Democratic Republic of Congo - Français.
