Ulu Tutong Dam is located in the remote jungle of Negara Brunei Darussalam. The dam forms a reservoir of some 80MCM of raw water which acts as a strategic reserve to regulate downstream river levels during times of low flow. The project includes the construction of a 24km access road, 440m long, 42m high embankment dam. The appurtenant works includes a 300m long diversion tunnel, 42m high draw-off tower, 40m wide fixed Ogee weir with a discharge capacity of 850m3/s.
This presentation discusses construction of the dam, appurtenant works, full depth central Plastic Concrete Cut-off wall, and the management of a large relic slip beneath the dam foundation.
