PBAPP’s portfolio of key water supply engineering projects undertaken in the period 1999 – 2020, for the benefit of Penang and its people, include:
• Assisting the Penang State Government to draft the Water Supply (Catchment Area) Order 2004 under the Penang Water Supply Enactment 2004, and the Water Supply (Catchment Area) Order 2009, to protect 62.9 sq. km of forestlands as Penang’s water catchment areas.
• Commissioning the 18,240 million litre Teluk Bahang Dam to increase Penang’s in-state raw water storage capacity by 65.7%, from 27,773 million litres (ML) in 1998 to 46,013 ML in 1999. The service area of this dam includes Teluk Bahang, the Batu Ferringhi tourist belt, and areas in Tanjung Bungah.
• Assisting the Penang State Government to secure a RM1.2 billion Federal grant in 2011 for the Mengkuang Dam Expansion Project (MDEP). Phase 1 of the MDEP involved the expansion of the dam, to increase its maximum effective capacity from 22,000 million litres (ML) in 2011 to 86,400 ML in 2020.
• Upgrading the Sungai Dua Water Treatment Plant’s maximum treatment capacity by 93.1%, from 636 MLD to 1,228 MLD. PBAPP also upgraded all other water treatment plants to increase Penang’s total maximum water treatment capacity by 78.8%, from 872 MLD in 1999 to 1,559 MLD in 2020, to achieve a water treatment reserve margin of 30.9%.
• Launching the Penang Water Supply Command Centre (PWSCC) in the Sungai Dua Water Treatment Plant in 2017 to realise the concept of real-time monitoring of all key dams, water treatment plants, pumping stations, reservoirs and major pipelines throughout Penang, 24/7.
• Increasing the total length of major water pipelines (100mm and above) by 39.0%, from 3,337 km in 1999 to 4,640km in 2020, in order to supply water to more people and businesses located in various areas within the state.
• Commissioning the 3rd Penang Twin Submarine Pipelines (3rd PTSP) project in 2020 to upgrade the maximum capacity of pumping water from the Sungai Dua WTP to Penang Island by 80.2%, from 393 MLD to 708 MLD.
