Braces for Extreme Weather: City Deploys Massive Pump Fleet and Accelerates Reservoir Dredging

Jakartaweekly.com – The Jakarta Provincial Government, through the Water Resources (SDA) Department, is intensifying its strategic measures to mitigate flood risks as the city faces the unpredictable challenges of extreme weather. This comprehensive approach focuses on reinforcing flood-control infrastructure, ensuring the readiness of an extensive pumping network, and maintaining the city’s complex polder systems to keep water flowing efficiently during heavy tropical downpours.

Ika Agustin Ningrum, Head of the Jakarta SDA Department, emphasized on Thursday (March 26) that her entire team is currently on high alert. She noted that the department is committed to ensuring every piece of flood-control equipment functions optimally before, during, and after periods of high-intensity rainfall. According to Ika, effective flood mitigation in a metropolis like Jakarta requires a synchronized effort that balances speed, precision, and the reliability of physical infrastructure.

The City’s Frontline: A Network of Over 1,200 Pumps

The primary line of defense for Jakarta’s residential and commercial hubs remains its robust pumping system. As of mid-March 2026, the SDA has activated a total of 668 stationary pumps distributed across 243 strategic locations throughout the capital. This infrastructure is further bolstered by a fleet of 537 mobile pumps stationed across all five administrative regions. These mobile units are particularly vital for the expat community to note, as they are designed to reach localized inundations in neighborhoods that may sit outside the immediate reach of permanent pumping stations.

Expanding Capacity Through Aggressive Dredging

To maximize the capacity of Jakarta’s drainage system, the SDA Department is also accelerating dredging operations across rivers, canals, and waduks (reservoirs). Since the beginning of January 2026 alone, crews have successfully removed over 123,000 cubic meters of sediment to ensure water bodies can hold as much volume as possible.

This ongoing effort builds upon the massive scale of work completed throughout 2025, where nearly one million cubic meters of silt were cleared from the city’s waterways. To maintain this momentum, the department has deployed a heavy-duty fleet consisting of 260 excavators and 465 dump trucks, all working to keep the city’s vital arteries clear of blockages.

The “Blue Squad” and Emergency Response

Beyond the heavy machinery, the city relies heavily on the dedicated personnel of the Water Resources Task Force, affectionately known as the “Blue Squad” (Pasukan Biru). These teams are stationed across the city to provide immediate field support, from manually operating pump systems to conducting routine inspections of drainage grates to prevent debris from causing flash floods.

Residents are encouraged to remain vigilant and monitor weather updates closely. For those living in the capital, the JAKI app remains a critical tool for reporting local flooding in real-time. In the event of an emergency, the city’s unified service hotline can be reached by dialing 112.
