The Murum Dam (Malay : Empangan Murum) is a gravity dam on the Murum River in Sarawak, Malaysia. Construction began in 2008, [4] the dam's reservoir began to fill in July 2013 and the first generator was commissioned in December 2014. [5] [6] The fourth and final turbine became operational on 8 June 2015. [7] Concerns have been raised about the displacement of the Dayak people and the removal of rainforest due to the construction of the dam.
The dam site is located on the Murum River, which is in the uppermost part of the Rajang River basin, 200 km (124 mi) from Bintulu. The upstream of Rajang river includes four steps, which are Pelagus, Bakun, Murum, and Belaga. The Murum Hydroelectric Project is the second Step-Hydroelectric Project of the four steps, and is 70 km (43 mi) from the constructing Bakun Hydroelectric Project downstream.
The Bakun Dam is an embankment dam located in Belaga District, Kapit Division, Sarawak, Malaysia, on the Balui River, a tributary or source of the Rajang River and some sixty kilometres east of Belaga. As part of the project, the second tallest concrete-faced rockfill dam in the world would be built. It would generate 2,400 megawatts (MW) of electricity once completed.
The Rajang River is a river in Sarawak, northwest Borneo, Malaysia. The river originates in the Iran Mountains, flows through Kapit, and then towards the South China Sea. At approximately 565 km long (351 mi), the river is the seventh-longest in Borneo and the longest in Malaysia.
Belaga is a district in Kapit Division, Sarawak, Malaysia. It is located on the upper reaches of the Rajang River, some 120 kilometers northeast of Kapit and slightly less than 100 kilometers from the South China Sea coast near Bintulu.
