GEORGE TOWN: The sinkhole that appeared on Jalan Dato Ismail Hashim in Bayan Lepas on Tuesday (Nov 4) is believed to be caused by a leaking underground pipe, leading to water seeping into the ground, says Zairil Khir Johari.
The state infrastructure, transport and digital committee chairman said that investigations are ongoing to determine whether the pipe belongs to the Penang Water Supply Corporation (PBAPP) or Indah Water Konsortium (IWK).
"Excavation at the site found underground water flow, likely causing the road to subside. The Public Works Department (JKR) has informed PBAPP and IWK for further investigation, and digging continues to locate the exact source of the leak.
"PBAPP will conduct tests to pinpoint the leak, while IWK will strengthen the drainage pipes located about 6m underground," he told reporters after visiting the site.
Bayan Lepas assemblyman Datuk Azrul Mahathir Aziz was also present.
To ensure public safety, Zairil said Jalan Kenari has been fully closed from the Jalan Dato Ismail Hashim junction, and motorists can use alternative routes via Jalan Sungai Ara 1, Jalan Persiaran Relau, or Jalan Kedidi.
Zairil mentioned that soil inspections and continuous monitoring are being conducted to ensure the area around the sinkhole is safe and free from cracks or further ground movement.
"Currently, there is no water accumulation or surface movement at the site, but we do not rule out underground water flow due to the pipe leak.
"We don't want to just fill the ground because ongoing water or soil movement below could cause the sinkhole to reopen," he said.
He added that IWK is inspecting all its pipelines across Penang to ensure they are safe, with plans to replace old pipes, especially in George Town, where some have been in use for over 50 years.
Zairil also denied claims that the sinkhole was linked to the construction of the Penang Mutiara Line Light Rail Transit (LRT) project, stating the affected area is not part of the project.
"It has nothing to do with the LRT project. This issue has been around for years and is due to old, worn-out pipes that need replacement. However, replacement work takes time and involves high costs," he said.
The sinkhole, located in front of SMK Sungai Ara, measures 5m long, 3.5m wide, and 1.9m deep. – Bernama
