KUCHING, 21 July 2026 – An engagement session with Sarawak Energy Berhad (SEB) on the proposed Mapai–Tondong 3rd and 4th 500kV Transmission Line Project was held at the Sarawak Rivers Board (SRB) Headquarters to discuss the project development progress and regulatory requirements relating to the proposed construction of overhead electric cable crossings over major rivers in Sarawak.
The session was chaired by the Asst. Controller (Enforcement and Legal), representing the Controller of SRB, and attended by senior officers from the Riverine Safety, Enforcement and Legal Sections and SRB Region I, Kuching. 
SEB presented an overview of the proposed 500kV transmission line project, which will extend approximately 368 kilometres from Mapai, Kanowit to Tondong, Bau, crossing 11 rivers across seven divisions in Sarawak. SEB also informed that the project is currently in the process of appointing a consultant to conduct the feasibility study as required by the State Planning Authority (SPA), the study outcome to serve as a reference for further project planning and implementation.
During the discussion, SRB highlighted that all proposed works within rivers and riverbank reserves must comply with the provisions of the Sarawak Rivers Ordinance, 1993 and its subsidiary regulation, particularly requirements relating to navigation safety, protection of river facilities, and river cleanliness management. 
SRB further advised SEB that upon completion of the feasibility study and during the implementation stage, the Project Proponent or appointed Contractor shall obtain SRB approval by submitting the required engineering drawings, supporting documents, prescribed fees, and conducting a joint site inspection. SRB will provide comments and recommendations based on the inspection findings to ensure compliance with the relevant requirements.
The engagement session concluded with constructive discussions, reaffirming the commitment of both parties to ensuring the project is implemented in compliance with statutory requirements while safeguarding navigation safety and supporting the sustainable management of Sarawak’s waterways.
