Penang’s Ampang Jajar Sungai Muda operations, which experienced a technical disruption on Saturday, have been fully restored.
The Ministry of Natural Resources, Environment and Climate Change (NRECC) in a statement today said the technical malfunction to the Supervisory Control and Data Acquisition (SCADA) system had caused a control gate to open without any warning causing the water in Sungai Muda to recede to 0.67 metres from 1.85 metres.
"Accordingly, the Sungai Muda River Basin Office has taken immediate action by manually closing the sluice gate yesterday at 7.30am and remedial action to raise the water level of Sungai Muda has been made by releasing water from the Beris Dam from 8.45am.
"As of 2.30 pm today, the water level in Ampang Jajar has risen to 1.7 metres," read the statement.
NRECC also informed that all gate operations at Ampang Jajar Sungai Muda will be done manually throughout this dry season, adding to ensure that the system functions well, all 14 actuators will be replaced immediately.
“The Department of Irrigation and Drainage is conducting a detailed investigation to identify the cause of the technical disruption to the sluice gate control system," it added.
According to the statement, the water supply is expected to fully recover in stages in all areas on Wednesday (May 17).
"At the same time, Syarikat Air Darul Aman Sdn Bhd (SADA) has installed submersible pumps to enable the Kulim HiTech, Sungai Petani and Pinang Tunggal Water Treatment Plants (LRA) to operate.
"Penang Water Supply Corporation (PBAPP) released 13,000 cubic metres per hour of water from Mengkuang Dam at 7.24am yesterday and helped Sungai Dua LRA to process 800 million litres per day of treated water," it said.
Kulim HiTech LRA’s operation was fully restored at 8 pm yesterday; Sungai Petani and Pinang Tunggal LRAs and Sungai Petani LRA Raw Water pump (45 per cent restored as of 10 pm); while LRA Pinang Tunggal Raw Water Pump (70 per cent restored as of 10 pm).
"The Sungai Dua LRA has been operating using the raw water source of the Mengkuang Dam with a 90 per cent production of treated water at 11.00pm yesterday," it added.
