Flooding in South Jakarta's Kebayoran Lama and Pesanggrahan since late Wednesday has forced some residents to leave their homes and disrupted traffic. Rain in upstream Bogor, West Java, is being blamed for the flooding, which authorities say could continue until Friday. Manager of Jakarta's Crisis Center, Heru Joko Santoso, said the Meteorology and Geophysics Agency (BMG) forecast Bogor and Puncak, both in West Java, would see three or four days of heavy rain, followed by several days of sunshine.
This patters is expected to prevail all month the transition period between the rainy season and the dry season, he told The Jakarta Post. Pesanggrahan River, which flows out of Bogor, burst its banks, flooding Pondok Pinang, Kebayoran Lama Utara and Cipulir subdistricts, all in Kebayoran Lama, and Pesanggrahan, Bintaro and Ulujami,in Pesanggrahan. The water level ranged between 10 and 190 centimeters, with Kebayoran Lama Utara being the hardest hit.
Heru said water in the flooded areas began to recede Thursday morning, flowing to West Jakarta. The water level at a river near to RCTI TV station (in Kebon Jeruk) began to rise this morning, he said. But the water level in Bintaro was still between 50 and 100 cm this afternoon. Heru said the water would completely recede only when Bogor and Puncak stopped seeing heavy rain.
In addition, the ocean tide is also a factor as it can stop floodwater from running through rivers to the sea, he said. Governor Fauzi Bowo said the city administration would take steps to restore the capacity of Pesanggrahan River. We've paid lot of attention to Ciliwung River but less to Pesanggrahan River, he said at City Hall. He said dredging the river was not enough, and that other steps would be necessary.
The capacity of rivers that run through the capital has been reduced as a result of the use of riverbanks for shanties, according to Fauzi. Such shanties appear, for example, in Manggarai (South Jakarta) and upstream in Angke (North Jakarta), he said. The administration, he said, needs to carry out its river restoration plan, which would involve land acquisition. Apart from the river restoration plan, the city is receiving loans of US$150 million from the World Bank to dredge rivers.
