Grand Sutera Housing in Kota Serang Frequently Flooded, BBWS C3 Dredges Cigeplak River
The Grand Sutera residential development in Panancangan District, Cipocok Jaya Sub-district, frequently suffers flooding due to overflow from the Cigeplak River. To address this issue, the Cidanau Ciujung Cidurian River Basin Authority (BBWS C3) has undertaken dredging operations on the Cigeplak River.
BBWS C3 Head Dedi Yudha Lesmana stated that his organisation deployed an Emergency Task Force for Flood and Water Control Operations (Satgaslak PBA) and a long-arm excavator to dredge the Cigeplak River segment at Grand Sutera on Tuesday, 10 March. Emergency response efforts were coordinated with the Banten Province Public Works and Spatial Planning Agency (PUPR).
According to Lesmana, flooding in Grand Sutera is caused by river shallowing due to channel narrowing and sedimentation. These conditions prevent the river from efficiently conveying water at high discharge rates. Sediment dredging and channel widening represent emergency measures to restore the river’s capacity and flow efficiency.
“Through this emergency intervention, the water-holding capacity of the Cigeplak River is expected to return to optimal levels, enabling better water flow and minimising inundation risk in surrounding areas. In addition to sediment dredging, field teams are also removing materials obstructing river flow,” he stated on Wednesday, 11 March 2026.
Lesmana explained that in December 2025, BBWS C3 had undertaken emergency river normalisation work and constructed temporary embankments using sandbags and gabions at three locations in the Grand Sutera residential area.
“Emergency response measures were implemented in December last year, whilst permanent solutions are scheduled for late March,” said Dedi.
“Whilst conducting emergency response, we are currently developing comprehensive plans to determine the most appropriate methods for addressing flooding in this area,” he added.
BBWS C3 is currently assessing river conditions, sedimentation levels, and other factors affecting flow capacity. The purpose of this study is to determine more effective and sustainable management approaches.
