Accepted Answer

A Landslide Near Haji Baki Traffic Lights Caused the Pipe Burst

A landslide in the vicinity of the Haji Baki traffic lights triggered the pipe burst, leading to significant ground movement that placed excessive stress on the 1,050mm Mild Steel Cement-Lined (MSCL) pumping mains pipeline. This excessive stress resulted in the pipeline's displacement and subsequent rupture, causing road shoulder embankment failure and soil erosion. The incident has led to low water pressure and unscheduled interruptions in water supply across several affected areas.
Landslide-Induced Ground Movement

Preliminary investigations indicate that the primary cause of the pipe burst was a landslide that occurred near the Haji Baki traffic lights. This natural event caused substantial ground movement, which directly impacted the integrity of the buried pipeline. The shifting earth exerted immense pressure on the 1,050mm MSCL pumping mains.
Pipeline Stress and Rupture

The excessive stress resulting from the ground movement, initiated by the landslide, led to the displacement and rupture of the MSCL pipeline. This failure point caused a significant discharge of water into the surrounding soil, which in turn accelerated erosion and compromised the structural support beneath Jalan Haji Baki and Jalan Batu Kitang. The embankment also experienced failure due to the loss of ground support.
Disruption to Water Supply and Infrastructure

The rupture of the pipeline and the subsequent embankment failure have disrupted the water pumping system, leading to critically low reservoir levels. Consequently, residents in the city centre, Petra Jaya, Kota Samarahan, and Padawan are experiencing low water pressure and unscheduled interruptions to their water supply. Emergency repair works are being planned, contingent upon safety assessments of the unstable ground conditions.
