The new Bintulu water supply was built in the early 1980s to serve a major development of the town of Bintulu in Sarawak, East Malaysia, arising from the extraction of natural gas from the South China Sea. The water supply was designed to supply 78 Ml/d. The works comprise earth dams forming a pumped storage reservoir, a river intake, pumping stations, pipelines, a water‐treatment works, treated water storage and a distribution system. The treatment works and distribution system are being built in two phases. The first phase was completed in 1983, and the second phase is to be constructed in 1990–91. The paper describes the initial planning of the scheme, including water‐demand forecasts, the design and construction of the Phase I works, and problems encountered during its operation. It also highlights the exceptionally rapid implementation programme and stability problems at the main earth dam.
