Ciliwung River Normalization Project Revived in Jakarta Amid Flood concerns
Table of Contents
Jakarta, Indonesia – Former Jakarta Governor Basuki Tjahaja Purnama, often referred to as Ahok, convened with current governor Pramono Anung at City Hall on Wednesday, August 20, 2025, to discuss Jakarta’s persistent flooding issues. A central focus of their discussion was the resumption of the Ciliwung River normalization project, a critical infrastructure initiative that experienced setbacks following Ahok’s term in office.
The Stalled Normalization Project
Ahok emphasized that approximately 16 kilometers of the Ciliwung River remain uncleared, hindering the project’s completion. He relayed positive feedback from former colleagues at the large River Basin Ciliwung Cisadane (BWSCC), indicating renewed optimism surrounding the initiative.”They were happy about it,” Ahok stated, referencing the potential for progress.
Governor Pramono Anung has reportedly issued a local determination to move the project forward. “Pak Pram had already issued a local determination as well. He mentioned earlier that this would be resolved,” ahok added, signaling a commitment to addressing the long-standing issue.
Prosperous completion of the Ciliwung River normalization is projected to considerably mitigate flood risks in Jakarta. According to Ahok, clearing the remaining 16 kilometers, along with the operation of associated embankments and reservoirs, would prevent the activation of a level 1 alert at the Katulampa dam, a crucial indicator of potential flooding.
Did you Know? The Katulampa dam,built in 1954,serves as an early warning system for Jakarta’s flood defenses,monitoring water levels in the Ciliwung River.
A History of the Ciliwung River Project
The Ciliwung River normalization project was initially launched during the governance of former Governor Joko Widodo (Jokowi).During Ahok’s tenure, some residents along the riverbanks were relocated to facilitate the project’s implementation.
However, the program stalled in 2017 under Governor Anies Baswedan, who shifted the focus to a “naturalization” approach, prioritizing ecological restoration and avoiding further evictions. Acting Governor Heru Budi Hartono later expressed interest in resuming normalization efforts, but faced challenges related to land acquisition. Governor Pramono Anung now appears poised to complete the project.
Recent flooding events in early March and july 2025 underscored the urgency of addressing the Ciliwung River’s capacity. Governor Pramono Anung identified the Ciliwung as the source of 40% of the flooding experienced in March, making its normalization a top priority among Jakarta’s 13 rivers.
Project Timeline and Challenges
The city administration has already mapped the land required for the river’s realignment. While acknowledging the difficulties associated with land clearance and potential resident resistance, Governor Pramono Anung assured a persuasive approach will be employed to encourage voluntary relocation. This approach aligns with principles of community engagement outlined in the World Bank’s guidelines on resettlement [[1]].
| Phase | Governor | Approach | Status |
|---|---|---|---|
| Initial Phase | Joko Widodo | Normalization (with relocations) | In Progress |
| Continued Phase | Basuki Tjahaja Purnama (Ahok) | Normalization (with relocations) | In Progress |
| shift in Strategy | Anies Baswedan | Naturalization (no relocations) | stalled |
| Revival Effort | Pramono Anung | Normalization (with voluntary relocation) | Ongoing |
Pro Tip: Understanding the past context of the Ciliwung River project is crucial for appreciating the current challenges and potential solutions.
What long-term strategies can Jakarta implement to enhance its resilience to flooding beyond the Ciliwung River project? How can the city balance infrastructure development with the needs of its residents?
Jakarta’s vulnerability to flooding is deeply rooted in its geographical location, rapid urbanization, and inadequate infrastructure. The Ciliwung River, despite ongoing efforts, remains a important source of concern. Experts suggest that a holistic approach, integrating green infrastructure, improved drainage systems, and community-based disaster preparedness, is essential for long-term resilience. The city’s commitment to lasting urban development will be critical in mitigating future flood risks.
