Building an Integrated Water Resource Management System in West Java

The project supported the establishment of a legal and institutional framework for Integrated Water Resource Management (IWRM) in Indonesia’s Cimanuk-Cisanggarung River Basin, which spans eight regencies in West Java and serves over 17 million people.

​

The project reviewed regional regulations against Indonesia’s Water Resources Law No. 17/2019, identifying gaps in planning mandates, institutional coordination, and stakeholder roles. It engaged more than 50 institutions through stakeholder mapping, consultations, and basin-level workshops.

​

Key activities included aligning the IWRM Master Plan with regional development and financial planning cycles, integrating flood mitigation, irrigation, and drinking water priorities, and supporting flood early warning planning for vulnerable areas such as Indramayu.

​

The project also strengthened the River Basin Council by clarifying decision-making roles, introducing conflict resolution measures, and proposing a Basin Secretariat Unit for continuous coordination. Women’s participation was mainstreamed through consultation requirements and access assessments.

​

As a result, five local regulations were reviewed and realigned with national IWRM principles. The basin-wide flood response plan was adopted by the West Java Provincial Government, and the CimanCis model is now being considered for replication in other Indonesian basins.
