Jakarta Urgent Flood Mitigation Project/Jakarta Emergency Dredging Initiative Project (JUFMP/JEDI Project)
Overview
Flood incidences are perennial occurrences in Jakarta and have been increasing in severity during the past decade. The last big floods in February 2007 affected more than 2.6 million people, forcing 340,000 people to flee their homes. Over 70 people died and outbreaks of disease affected over 200,000 people. The estimated financial and economic losses from this event amounted to US$900 million. Inundations continue to occur under any sustained rainfall conditions. To improve Jakarta’s flood management system, this project will dredge selected floodways, canals and retention basins to improve their flow capacities and dispose dredge materials in proper facilities.
Challenge
Thirteen major rivers flow northwards through Jakarta into the Java Sea. The 13 rivers, together with a large number of drainage channels, form the macro drainage system of Jakarta. Due to inadequate maintenance and poor solid waste management, there is significant sediment and solid waste build up in these channels. In addition, urbanization trends are central to the causes of floods in Jakarta which have led to the deterioration of several critical factors. The encroachment and/or development of critical catchment areas have resulted in both increased rainwater runoff and lack of natural storm water retention areas both within the city and in upstream areas of the catchment. Flood events in Jakarta are expected to become more frequent in coming years, with a shift from previously slow natural processes with low frequency to a high frequency process resulting in severe socio-economic damage.
