The target window is Sept 3 to 5, but the operation still depends on suitable cloud formations. Agencies are due to meet on Sept 1 to decide how it will be carried out, so the dates are not a confirmed flight schedule. The exercise is intended to support both water sources and power dams.

The wider response is already moving. From Aug 18 to 29, JBALB’s 24 water tankers and 74 contracted lorries—98 vehicles in all—made 680 trips and delivered 3.344 million litres across Samarahan, Sri Aman, Betong, Limbang and Miri. The disaster committee has also approved RM400,000 for additional water tanks and central collection points in larger villages.

Separately, bottled-water assistance recorded 1,943 cases from Jan 1 to Aug 26, covering 49,523 families and 225,822 people. Communities facing supply interruptions should follow JBALB or Sarawak Water notices for the operating details of their local tanker routes and collection points.
