Located on the island of Borneo in Southeast Asia, Brunei has adequate water sources but the development of the water supply system has been affected by distance and local conditions. In the 1990’s, the Bukit Barun Water Treatment Works was constructed to cater for the increasing water demand in the Brunei-Muara district.
The Bukit Barun WTW can supply nearly 80% of water in the area. For several years, the Water Services Department in Brunei has concentrated on improving the production capacity and robustness of the water supply system. Part of the improvement works involves a £14m extension of Bukit Barun WTW which will increase its capacity to 490 million litres of water daily in order to meet increasing water consumption demand.
