JAKARTA - The DKI Jakarta Provincial Government admits that the capacity of existing flood control infrastructure is beginning to be overwhelmed by extreme rainfall due to climate change. Rain with an intensity above the design capacity is said to be one of the causes of flooding that still often occurs in a number of Jakarta areas.
Head of the DKI Jakarta Water Resources Office Ika Agustin Ningrum explained that most of the flood control infrastructure in Jakarta was designed to accommodate rainfall of around 100 to 150 millimeters. Meanwhile, in recent years, the intensity of rainfall has increased to 250 millimeters.
"Flood control infrastructure such as water pumps, river embankments, drainage channels, reservoirs/situ/embung are built with design capacity or the ability to accommodate and drain surface runoff from a certain amount of rainfall. However, in recent years due to climate change, the rainfall that occurs tends to be high and extreme, namely 150-250 mm," said Ika to reporters on Thursday, May 28.
According to him, this condition makes the capacity of existing infrastructure no longer optimal when extreme rain hits Jakarta. The addition of flood control capacity is said to require large land and costs.
"So, the construction of flood control infrastructure in Jakarta is effective for rainfall of 100-150 mm, while for higher rainfall, a larger infrastructure capacity is needed," said Ika.
The DKI Provincial Government itself is currently operating hundreds of pumps to help control flooding in the capital. Based on data as of May 18, 2026, there are 683 stationary pump units spread across 246 locations and 540 mobile pumps in five administrative city areas and the Thousand Islands.
Meanwhile, for dams and sodetan, the DKI Provincial Government emphasized that the infrastructure is under the authority of the central government and the West Java Provincial Government. "The DKI Jakarta Provincial Government does not have dams, dams or sodetan," he explained.
Ika said that the Sukamahi Dam was managed by the Ministry of Public Works (PU), the Katulampa Dam was under the management of the West Java Regional Agency for Natural Resources and Environment together with the South Jakarta Regional Agency for Natural Resources and Environment, while the Ciliwung Sodetan in Jatinegara was the responsibility of the PU Ministry.
To strengthen flood control, the DKI Provincial Government through the Water Resources Office (SDA) has prepared a number of infrastructure development projects in 2025 to 2027 through the JakTirta program and the National Capital Integrated Coastal Development (NCICD).
Some of the projects prepared include the construction of water management systems and pumps in Bulak Cabe, Pegangsaan Dua, Cilincing KBN, to Daan Mogot. In addition, the construction of new reservoirs and ponds will also be carried out in Pondok Labu, Kebagusan, and Sunter Hulu.
Not only that, the normalization of rivers is also being pushed back at three priority points, namely the Ciliwung River, Kali Krukut, and Kali Cakung Lama. Meanwhile, for coastal area protection, the DKI Provincial Government continues to build the NCICD coastal protection embankment in the Mutiara Beach, Muara Baru, and Kali Blencong areas.
