Sarawak Energy Addresses Baleh Dam Seepage Concerns with Assurances and Monitoring

Sarawak Energy Berhad (SEB) has reassured the public regarding the stability and safety of the cofferdams for the Baleh dam project, explaining that observed seepage is a normal occurrence within the project's design parameters. The company is actively monitoring water levels at all its hydropower sites, particularly during periods of heavy rainfall, and has engaged with relevant stakeholders to keep them informed. SEB has also established a dedicated channel for public feedback and concerns.
Cofferdam Seepage Is a Designed Phenomenon

SEB has clarified that the seepage observed from the Baleh dam's cofferdams is a common and anticipated phenomenon. The cofferdams are constructed using rock-fill and gravel materials to create a dry environment essential for the main dam's construction. This type of material inherently allows for some water seepage, which has been factored into the design of the structures to ensure their integrity.
Adherence to International Safety Standards

The construction of the Baleh project adheres to stringent international best practices for large dams. Primary standards and guidelines are provided by the International Commission on Large Dams (ICOLD), a globally recognised body that ensures the safe construction and operation of hydropower projects. This commitment to international standards is complemented by comprehensive geological investigations and studies conducted at every stage of the project's development, from initial feasibility to detailed engineering design.
Continuous Monitoring and Stakeholder Engagement

Sarawak Energy is maintaining close surveillance of water levels across all its hydropower project sites, with heightened attention during periods of significant rainfall. The company has proactively communicated with and updated key stakeholders, including the Kapit Division Resident’s Office, the Bukit Mambong District Office, and various community groups, ensuring they are informed about the project's status and any developments.
Public Grievance Mechanism

To facilitate open communication and address any public apprehension, SEB has implemented a dedicated grievance mechanism. Individuals with concerns or queries regarding the Baleh dam project can reach out to the project team through a provided feedback hotline at +6019 882 8641 or via email. This channel ensures that feedback is received and addressed promptly. The river diversion and closure works for the Baleh hydropower project were successfully completed between October 1 and October 16, 2020. The 1,285-megawatt Baleh dam, with an estimated cost of RM8 billion, is slated for commissioning in 2026, joining other significant hydropower facilities in Sarawak such as Bakun, Murum, and Batang Ai.
