Malaysia’s first Free Trade Zone (or FTZ) was established in Bayan Lepas, near the Penang International Airport, under the leadership of Tun Dr. Lim Chong Eu, the 2nd Chief Minister of Penang. It heralded the beginning of the manufacturing era in Penang, with the arrival of the first wave of multinational manufacturing corporations (MNCs).
The Penang Water Authority, or “Pihak Berkuasa Air” (PBA), was set up to supply water in Penang.
Phase 1 of the “Muda River Water Scheme” (MRWS) officially opened by Tun Abdul Razak bin Hussein, the 2nd Prime Minister of Malaysia, in Seberang Prai. The MRWS was funded by an Asian Development Bank (ADB) loan, with a “water guarantee” from Kedah as a “pre-condition”. This guarantee, as provided by Kedah, allowed Penang to abstract water from the Muda River (Sungai Muda), without any conditions or payment.
PBA began abstracting raw water from Sungai Muda at the Lahar Tiang Intake in Seberang Prai. The raw water was pumped, via the 14km Sungai Dua Canal, to the Sungai Dua Water Treatment Plant (WTP).
Package 1 of the Sungai Dua WTP commissioned, with an initial maximum water treatment capacity of the Sungai Dua WTP was 136 million litres per day (MLD).
1st Penang Twin Submarine Pipelines (1st PTSP) commissioned, with a maximum capacity of 143 MLD, to deliver treated water from the Sungai Dua WTP to Penang Island.
