Penang Diversifies Water Distribution to Meet Rising Demand

Penang is implementing a comprehensive strategy to diversify its water distribution network, investing RM1.115 billion over the next four years through its Water Contingency Plan 2030 (WCP 2030). This initiative aims to address the increasing water consumption, which has risen to 887 million litres per day (MLD) in the first half of this year from 843 MLD in 2019. The Penang Water Supply Corporation (PBAPP) has already committed RM69.15 million to WCP 2030 projects and plans to complete six more key projects within the next four years.
Decentralisation from Sungai Dua WTP

A core element of PBAPP's strategy is to decentralise the water distribution system, moving away from over-reliance on the Sungai Dua Water Treatment Plant (WTP), which currently supplies 85% of Penang's water. This approach seeks to create a more resilient and robust supply network. The recently completed Package 12A project at the Sungai Muda WTP has already increased its treatment capacity by 114 MLD, bringing the total to 1,726 MLD from a previous 1,612 MLD.
New Water Treatment Plants and Dam Utilisation

The plan includes the construction of new water treatment plants (WTPs) to bolster capacity and serve different regions. A new WTP with a 114 MLD capacity is slated for Central Seberang Perai, utilising water from the Expanded Mengkuang Dam. Furthermore, two additional WTPs, each with a 114 MLD capacity, are planned for Sungai Kerian and Sungai Muda to serve South Seberang Perai and North Seberang Perai, respectively.
Enhanced Pipeline Infrastructure

Significant investment is also being directed towards upgrading and expanding the pipeline network. This includes the construction of dedicated and submarine pipes to ensure direct water supply to the island. Three major pipelines are scheduled for implementation between 2025 and 2026, with an estimated cost of RM189 million. These will comprise a 13km pipeline connecting the Sungai Dua WTP to Butterworth, a 3.9km pipeline from Macallum to Bukit Dumbar on the island, and a pipeline crossing the Sungai Perai river. These new pipelines will enable PBAPP to pump water at higher pressures to approximately 465,000 consumers.
