The Mengkuang Dam has been expanded to meet Penang’s water supply needs during annual dry seasons in the 21st Century.
On 14.12.1985, the Yang DiPertua Negeri (Governor) of Penang, TYT Tun Datuk Dr. Haji Awang bin Hassan, officially opened the “original” Mengkuang Dam. About 35 years ago, its maximum effective capacity was 22.0 billion litres.
The Mengkuang Dam Expansion Project (MDEP) is undertaken by the Malaysian Federal Government as part of its commitments to Penang for migrating to the National Water Services Restructuring Initiative (NWSRI) in 2011.
Works commenced from 2011. Phase 1 of the MDEP saw the construction of a new dam with a crest length of 2km and a maximum height of 56.6m; as well as the raising of the original dam structure by 11m and other associated works.
The two dams were subsequently “joined” to form one significantly larger body of water with a maximum surface area of 3.4 sq. km (as compared to 1.74 sq. km previously). Today, the maximum effective capacity of the dam is 86.40 billion litres.
On 26.10.2020, the Federal Government officially handed back the expanded Mengkuang Dam to the Penang State Government.
