Penang will undergo its only scheduled water supply interruption (SWSI) for 2025 from April 25 to 28, affecting over 340,000 consumers across the state. The Penang Water Supply Corporation (PBAPP) has assured that efforts will be made to restore water in stages, with 40% of consumers expected to see their supply return within the first 24 hours.

PBAPP executive officer Datuk K. Pathmanathan stated that water supply is projected to resume for 136,683 consumers within a day, 163,502 within 48 hours, and the remaining 41,523 within 60 hours. Full restoration is anticipated by April 28.

“The disruption is scheduled to start on Friday night and over the weekend to minimise inconvenience,” he said, noting that the interruption is essential for carrying out 23 critical water works projects in 26 locations. These upgrades will benefit 465,000 consumers serviced by the Sungai Dua Water Treatment Plant (WTP), the state’s largest.

Affected areas on the mainland include parts of North, Central, and South Seberang Perai, such as Butterworth, Alma, Permatang Pauh, Batu Kawan Industrial Areas, and northern Nibong Tebal. Key unaffected areas include Bertam, Kepala Batas, Bukit Mertajam, and southern Nibong Tebal.

On Penang Island, affected areas in the northeast district include George Town, Jelutong, Gelugor, and USM. Meanwhile, areas such as Air Itam, Tanjong Tokong, and Batu Ferringhi will not be affected. In the southwest district, disruptions will occur in Bayan Baru, Batu Maung, and Teluk Kumbar, while Balik Pulau (north), Teluk Bahang, and Sungai Pinang will remain unaffected.

PBAPP is prioritising major industrial zones and the Penang International Airport for early restoration, aiming for minimal disruption to essential services and businesses.
