The Ulu Tutong Dam is an embankment dam currently under construction on the Sungai Tutong River in Tutong District, Brunei. The primary purpose of the dam is to increase water supply in Tutong and Brunei-Muara Districts by as much as 156,000,000 m3 (126,000 acre·ft) annually.[1] When complete it will have a normal reservoir volume of 100,000,000 m3 (81,000 acre·ft) and be the largest water supply project in the country.[2] In February 2010 Sinohydro won the bid to construct the US$85.5 million project and construction began soon thereafter.[3] It was originally expected to be complete in February 2014 but the date was pushed to February 2015 due to difficulties at the construction site. The dam is owned by the Public Works Department of Brunei.[4]
