The Penang Water Supply Corporation (PBAPP) said the final phase of water supply restoration involving the remaining users in Seberang Perai and those at the end-of-line and hilly areas in the southern part of the island was completed by 6am as per its schedule, Bernama reported.

The restoration was carried out in four phases with the first phase ensuring about 33% of the users having their water supply return to normal on Friday, two days after the shutdown for repairs to the main water treatment plant in Sungai Dua.

Meanwhile, on the leak in the Sungai Perai underwater pipeline which was detected on Friday, PBAPP said it resulted in an estimated loss of 110 million litres per day (MLD) of non-revenue water (NRW).

“Recovery operations in Sungai Perai are now ongoing at the emergency response stage with close monitoring being carried out by commercial divers.

“The next stage is an interim solution, which is the proposed installation of a 2mm x 600mm pipeline next to the Ampang Jajar bridge to replace the damaged riverbed pipeline,” it said, according to Bernama.

PBAPP added that preliminary work for the replacement of the pipe has already started and is expected to be completed within 21 days.
