Control Tidal Flooding on Jakarta's Coastline, Pramono Adds 5 Giant Pumps in Ancol
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 stated that the addition of these pumps will enhance 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 5 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,” said Pramono during his inspection of the Ancol Pumping Station on Tuesday (7/4/2026).
Consequently, the total water control capacity in Ancol and its surroundings will reach approximately 80 cubic metres per second or 80,000 litres per second.
According to Pramono, this capacity increase will have a significant impact on reducing flooding in North Jakarta, which has a fairly extensive catchment area.
“If this can be implemented, it will be very beneficial in addressing the flooding issues that have long occurred in Ancol and surrounding areas, with a catchment area of around 2,000 hectares,” he said.
Meanwhile, the Head of the Jakarta Water Resources Agency (SDA), Ika Agustin, explained that this project is part of the Jaktirta Project to be built in five Jakarta regions.
In the Ancol area, the pumping system will be strengthened with the addition of five new pump units to support the three existing pumps currently in operation.
“There are currently three existing units, each with 5 cubic metres per second. We will add five more pumps, making the total at this location around 40 cubic metres per second,” Ika clarified.
“For this location, the pumps used are from Japan, under the Ebara brand. In general, we also use several other brands such as Torishima from Japan, KSB from Germany, and Grundfos from Denmark,” she revealed.
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.
The project was contracted in December 2025 and is targeted to begin operations in 2027. The Pemprov DKI aims to have part of the system functional by May 2027, coinciding with Jakarta Anniversary Day.
To anticipate the rainy season before the project is completed, the SDA Agency is also preparing mitigation measures by adding around 25 large-capacity mobile pumps, each approximately 1,000 litres per second.
