Ancol Pump Capacity to be Increased to 40,000 Litres Per Second
Governor of DKI Jakarta, Pramono Anung, inspected the Ancol Pump water management system in Tanjung Priok, North Jakarta. He assured that the pump capacity in the area will be significantly increased to address flooding in coastal regions.
Pramono explained that the pumps currently managed by the DKI Provincial Government have a capacity of around 15,000 litres per second. This capacity will be augmented by five new pump units, each with a capacity of 5,000 litres per second, bringing the total to 40,000 litres per second, equivalent to the pumps owned by the central government.
“One pump managed by the central government has a capacity of approximately 40,000 litres per second. In DKI, it is currently 15,000. It will be increased by adding five times five, so it will become 25, plus 15, making 40,000 litres per second,” said Pramono in Tanjung Priok, North Jakarta, on Tuesday (7/4/2026).
According to him, this capacity increase is very important because the catchment area of the Ancol Pump covers around 2,000 hectares, including areas vulnerable to flooding and tidal surges.
“If this can be implemented, it will be very beneficial in addressing the flooding issues that have occurred in the Ancol area and its surroundings,” he stated.
Pramono also urged the Water Resources Agency staff to strengthen the maintenance of all pumps, considering that Jakarta will enter a long dry season due to El Niño starting from mid-April to September.
“The pumps must be maintained. We are preparing for September and beyond, including continuing the normalisation of rivers that have been decided, such as Ciliwung, Old Krukut, Old Cakung, and Krukut,” he explained.
Nevertheless, Pramono remained realistic. He stated that pooling could occur if extreme rainfall coincides with tidal surges.
“If the rainfall exceeds 200 mm and there is a tidal surge, Jakarta will definitely have pooling. But with the experience we have, on average, it recedes within 3-5 hours once the tide drops,” he emphasised.
