The Ciliwung-Cisadane Flood Control Office (BBWSCC) has been alerting mobile pumps in Bukit Duri, South Jakarta. It is aimed to anticipate flooding. 

It is because Bukit Duri is still prone to inundation if the Katulampa Sluice Gate shows  on alert I. This is because construction of sheet pile and parapet wall on Ciliwung riverbank is not yet completed. 

"If the citizen settlement is inundated, we will do pumping," said Fikri Abdurrachman, Head of BBWSCC's Water Resources Network Management, Wednesday (2/8).

After sheet pile and parapet wall is installed, the drain will also be arranged. Besides polder, there will be sluice in each connecting drain that flows from the settlement.

"Open-close system on the sluice will be set by the officer. The time is adjusted to the field condition," he finished.
