Koh Samui Implements Water Rationing Amid Severe Shortage
The Provincial Waterworks Authority (PWA) will begin rotating water supply zones on Koh Samui starting August 3, 2026, due to a critical deficit in production capacity.
According to a report by Khaosod Online Thailand, the Provincial Waterworks Authority (PWA) branch on Koh Samui has announced a seven-day water rotation schedule beginning August 3, 2026. This measure follows a prolonged drought that has significantly depleted raw water sources, leaving the island unable to meet local demand.
Currently, the PWA can produce only 16,000 cubic meters of water per day via the mainland pipeline, while the daily demand on the island reaches 34,000 cubic meters. This creates a daily shortfall of 18,000 cubic meters. To manage this, the PWA has divided the island into specific zones—categorized as yellow and red-green—with a rotating supply schedule intended to ensure equitable distribution across all areas.
For residents and travelers, this situation may lead to low water pressure or intermittent supply disruptions, impacting daily activities such as cooking and hygiene. The PWA is urging the public to store water for use during non-supply periods and to practice strict water conservation. While the rotation schedule is set for seven days, it remains to be confirmed how long these restrictions will persist if drought conditions continue. Visitors are advised to check with their accommodation providers regarding local water availability and to use water sparingly during their stay.
