CHIANG RAI – Chiang Rai Governor Chuchip Pongchai has ordered an urgent acceleration of flood defense repairs along the Sai River, directing local authorities to complete reinforcement works by June 2026.
The move comes as seasonal rains begin to lash the border district, raising fears of a repeat of the catastrophic 2024 floods. With permanent flood walls not expected until 2032, the provincial government is currently mobilizing local budgets to secure five high-risk “gap” points with giant sandbags (big bags) and is preparing to demolish buildings that obstruct natural water drainage.
The memory of the 2024 Sai River overflow, which devastated both the Thai side in Mae Sai and the neighboring Myanmar town of Tachileik, remains a vivid trauma for residents. Although the Royal Thai Army’s Engineer Department installed temporary and semi-permanent barriers shortly after that disaster, recent inspections reveal that these defenses are not yet 100% ready for the 2026 monsoon season.
Governor Chuchip has coordinated with the 3rd Army Area and local administrative organizations (LAOs) to bridge these gaps. The strategy is straightforward: use immediate local funding to shore up defenses while waiting for long-term federal projects to materialize.
Key Protection Measures Underway
To ensure the safety of the business district and residential zones, the provincial authorities have outlined a three-tier response plan:
- Immediate Reinforcement: Five critical locations within the Mae Sai and Wiang Pang Kham sub-districts are being reinforced with “big bags” and additional sand-filling. These works are strictly scheduled for completion by the end of June.
- Removing Obstructions: The government has allocated approximately 39.3 million baht from the 2025 emergency reserve budget to demolish buildings and structures that block the river’s flow. This project has already received approval from the Ministry of Interior.
- The Long-Term Shield: A massive 2.95-billion-baht permanent embankment and drainage system project by the Department of Public Works and Town & Country Planning is in the pipeline. However, this comprehensive infrastructure is currently in the public hearing and design phase, with a projected completion date of 2032.
The urgency of the situation has forced a shift in how these projects are funded. Rather than waiting for the multi-billion baht federal budget to trickle down, Governor Chuchip has instructed local municipalities to tap into their own coffers for materials and labor. This “bottom-up” funding approach aims to bypass bureaucratic delays that often hamper large-scale construction.
According to reports from SondhiTalk, the provincial government is also in the process of coordinating with the Treasury Department to reclaim land areas necessary for widening the water path. This is a sensitive but necessary step to prevent the “bottleneck” effect that contributed to previous disasters.
For the people of Mae Sai, the news is a mixture of relief and anxiety. While the immediate repairs provide a sense of security, the ten-year wait for a permanent solution highlights the vulnerability of the region. Experts suggest that as weather patterns become more unpredictable, these temporary “big bag” solutions must be monitored constantly.
“We cannot wait for the 2032 permanent wall while the clouds are gathering today,” one local official noted. The focus remains on the June deadline—a date that marks the beginning of the most dangerous period for the Sai River basin.
Summary of the Flood Defense Plan
| Project Type | Timeline | Budget/Source | Status |
|---|---|---|---|
| Temporary Big Bags | June 2026 | Local Admin Budget | Active / Urgent |
| Obstruction Removal | 2025-2026 | 39.3 Million Baht | Pending Land Approval |
| Permanent Flood Wall | 2032 | 2.95 Billion Baht | Design & Hearing Phase |
As the first rains of the season arrive, the effectiveness of these makeshift barriers will be put to the ultimate test. For now, the Governor’s message is clear: every day without a flood is a day that must be used to build a higher wall.
