Samui enforces strict water rationing amid severe drought conditions
Samui has entered a strict water rationing phase due to an unprecedented drought that cut the island's drinking water production to 40% of normal. Local authorities have introduced a rotational water supply schedule and are urging everyone to save water. Emergency actions include pipeline upgrades, repairs to water treatment systems, and efforts to induce artificial rain. The government is also planning a long-term water security program to prevent future shortages.
Key Points
- 1Water production on Samui has dropped to 40% of normal due to severe drought.
- 2The main underwater pipeline from Surat Thani supplies only 16,000 cubic meters daily versus 34,000 needed.
- 3A rotational water supply schedule is now active, with calls for strict water conservation.
- 4Emergency measures include pipeline capacity increase, system repairs, and artificial rainmaking efforts.
Samui is facing a critical water shortage due to an abnormal drought, prompting local authorities to implement strict water rationing. The island's main freshwater supply from an underwater pipeline connected to Surat Thani province now delivers only 16,000 cubic meters daily, far below the estimated demand of 34,000 cubic meters. Reservoirs are rapidly depleting, and elevated areas are almost completely cut off from centralized water supply.
A rotational water supply schedule by zones is now in effect, urging residents and businesses to conserve water strictly. Many hotels and enterprises have shifted to autonomous water sourcing by purchasing tanker deliveries, which significantly raises their operational costs. The Ministry of Interior has taken special control over the situation as of July 29, signaling the seriousness of the drought crisis.
Emergency measures announced include plans to increase pipeline capacity by 4,000 cubic meters per day, repair reverse osmosis systems, optimize raw water sources, and coordinate with the Royal Rainmaking Department to induce artificial rainfall. These short-term actions aim to ease the immediate shortage but are insufficient to fully resolve the problem.
The Thai government is developing a long-term water security program for Samui, focusing on major infrastructure upgrades, expanding raw water source networks, and establishing a robust resource transmission system. This strategy intends to prevent future water crises and ensure sustainable water availability for the island's residents and visitors.
