DKI to build five giant pumps in Ancol to control tidal flooding

The Jakarta Provincial Government (Pemprov DKI Jakarta) is adding five giant pumps in the Ancol area, North Jakarta, to control tidal flooding in coastal regions. Jakarta Governor Pramono Anung Wibowo stated that this addition will increase the water management system’s capacity, particularly in flood-prone areas such as Pademangan and Gunung Sahari. “Currently, the capacity at this location is around 15 cubic metres per second or 15,000 litres per second. We will add five pumps, each with a capacity of five cubic metres per second or 5,000 litres per second, bringing the total to around 40 cubic metres per second or 40,000 litres per second,” Pramono said after inspecting the construction of the Ancol Pump House Water Management System in Pademangan, North Jakarta, on Tuesday. Furthermore, Pramono explained that the pump system in the area will be integrated with pumps owned by the central government in Sentiong Ancol, which also have a capacity of around 40 cubic metres per second or 40,000 litres per second. Thus, the total water control capacity in the Ancol and surrounding areas will reach around 80 cubic metres per second or 80,000 litres per second. “If this can be implemented, it will be very beneficial in addressing the flooding issues that have occurred in the Ancol and surrounding areas, with a catchment area of around 2,000 hectares,” Pramono clarified. Meanwhile, the Head of the Jakarta Water Resources Agency (SDA), Ika Agustin, explained that this project is part of the Jaktirta Project, which will be built in five areas of Jakarta. In the Ancol area, the pump system will be strengthened with the addition of five new pump units to support the three existing pumps that are currently operational. “There are currently three existing units here, each with five cubic metres per second. We will add five more pumps, so the total at this location will be around 40 cubic metres per second,” Ika explained. In the future, the Ancol area will be developed into a large polder system covering up to around 5,000 hectares. Water from that area will be channelled and discharged directly into the sea as part of an integrated flood control system. Ika said the project has been contracted since December 2025 and is targeted to start operating in 2027. In addition, the Provincial Government of DKI targets that part of the system can already be operational in May 2027, coinciding with Jakarta Anniversary Day.
