JAKARTA - DKI Jakarta Development and Environment Assistant Yusmada Faizal explained the causes of floods that have occurred from yesterday to today in a number of Jakarta areas, especially in East Jakarta.

Yusmada said, the level of rainfall since Thursday, February 18th until today has been very high, which has exceeded the capacity of the drainage system in Jakarta.

"Jakarta has experienced rain from yesterday afternoon, and it continues until this morning. It has rained evenly throughout Jakarta, ranging from heavy, very heavy, even extreme categories," said Yusmada at the City Hall of DKI, Central Jakarta, Friday , February 19.

Yusmada explained, the highest rainfall since yesterday to today is in the Halim Perdanakusuma area with 160 millimeters per day, Manggarai and Pasar Minggu 130 millimeters per day, and Sunter Hulu 107 millimeters per day.

Unfortunately, the drainage system in DKI is built with a rainfall capacity of between 50 and 100 millimeters per day. Drainage in the area is unable to accommodate water with high rainfall, resulting in water overflows to settlements.

"Please note, our drainage system is designed based on rainfall of 50 to 100 milliliters per day. Hence, if there is extreme rain up to 160 millimeters, it will overflow," he explained.

Today, the DKI Regional Disaster Management Agency (BPBD) recorded that 99 RTs in Jakarta were flooded today. In details, there are 3 RT in West Jakarta and 96 RT in East Jakarta.

Some areas have receded. However, RW 02 and RW 03, Cipinang Melayu Urban Village, were still flooded. BPBD is doing pumping at PHB Sulaiman and Kalimalang.

"As a result of the rain yesterday afternoon, generally it was at 5 o'clock yesterday. Likewise, the one that rained last night, this morning, at 9 am it had receded. Except for areas like the one in Cipinang Melayu, that includes the rain at Halim, "he said.

"Then, the water level in the Sunter River is still high. All the fleets, all the potential, all of our equipment, we mobilize to handle the puddle in Cipinang Melayu," he added.
