"Flooding is mostly triggered by low topography," he expressed, Sunday (9/23).

In Cengkareng, he explained, Rawa Buaya Urban Village is prone to flooding, especially in Kedaung Kali Angke Urban Village.

Then in Kalideres, flood-prone areas in Kamal Urban Village are bordering the sea.

"Flood and inundation in Kalideres is caused by rob (tidal wave)," he stated.

While in Kembangan Utara area, flood is caused by overflowing waters of Pesanggrahan River that has no sheet pile.

"Inundation is also spotted in a number of points along Sekretaris River that pass in Kebon Jeruk Sub-district, as they have not matched the trajectory," he told.

To handle it, his side would optimize pump house in some areas that have low topography.

Currently there are totally 98 stationer pumps installed in 31 pump houses in West Jakarta.

"Around 30 percent of pump houses are in Cengkareng area. And the rest are in Kebon Jeruk, Kembangan, Taman Sari, Palmerah, Grogol Petamburan, and Kalideres areas. As for the Tambora, pump house is still unavailable, but mobile pump will be installed if flood happens," he stated.
