Cambodia’s Ministry of Environment has successfully prevented more than 26 million cubic meters of wastewater from contaminating rivers, lakes, and other natural water bodies since the beginning of 2025, according to an official report released on April 1, 2026.
In the first quarter of 2026 alone (January to March), authorities blocked over 6.39 million cubic meters of untreated wastewater from entering the environment. For the full year 2025, the ministry prevented more than 20 million cubic meters from polluting public and clean water areas nationwide.
The combined total since the start of 2025 now exceeds 26 million cubic meters, significantly reducing risks to public health, ecosystems, and local livelihoods across Cambodia.
📊 Key Statistics at a Glance
| Period | Wastewater Prevented (million m³) |
|---|---|
| 2025 (full year) | 20+ |
| Q1 2026 (Jan–Mar) | 6.39 |
| Total since 2025 | 26+ |
🔧 Automated Monitoring Systems: A Game Changer

To strengthen environmental protection and ensure biodiversity sustainability, the Ministry of Environment has mandated the installation of automated wastewater monitoring systems and data management tools at factories and high‑risk enterprises. These systems transmit real‑time water quality data directly to the ministry.
As of March 2026, 57 out of 68 factories and companies that have signed agreements with the ministry have installed automatic water quality monitoring equipment. The remaining 11 are expected to comply soon.
This initiative allows authorities to detect violations instantly, enforce regulations, and prevent illegal dumping before it harms the environment.
🌍 Why This Matters for Cambodia

Cambodia’s rapid industrialization has brought economic growth but also environmental challenges. Untreated industrial wastewater poses serious threats to:
- Public health – contaminated water sources lead to waterborne diseases
- Ecosystems – fish kills, loss of aquatic biodiversity
- Livelihoods – farmers and fishermen depend on clean rivers and lakes
The Ministry’s proactive approach not only protects natural resources but also supports Cambodia’s commitment to the Sustainable Development Goals (SDGs), particularly Goal 6 (Clean Water and Sanitation) and Goal 14 (Life Below Water).
🤝 Ministry Thanks Responsible Factories

The Ministry of Environment expressed gratitude to participating factories and enterprises for their contribution to environmental protection, particularly in:
- Reducing water pollution
- Improving sanitation and public health
- Supporting sustainable industrial practices
Officials also called on more companies with pollution risks to comply with environmental laws and regulations, aiming to curb water, land, and air pollution while supporting sustainable development and increasing green coverage nationwide.
🔮 Future Outlook
The Ministry of Environment has set ambitious targets for 2026 and beyond:
| Goal | Target |
|---|---|
| 100% compliance | All 68 high‑risk factories install monitoring systems |
| Expansion | Include additional sectors (e.g., agriculture, mining) |
| Public transparency | Publish regular water quality reports online |
| Green coverage | Increase national forest and wetland protection |
Travelers and eco‑conscious investors will find Cambodia increasingly committed to environmental stewardship, making it a more attractive destination for sustainable tourism and green investment.

❓ Frequently Asked Questions
What types of factories are required to install monitoring systems?
High‑risk enterprises, including textile factories, beverage producers, food processors, and other industries that generate significant wastewater.
How does the automated system work?
Sensors continuously measure pH, temperature, chemical oxygen demand (COD), and other pollutants. Data is transmitted in real‑time to the Ministry of Environment.
What happens if a factory violates wastewater standards?
The ministry can issue fines, suspend operations, or pursue legal action. The automated system allows immediate detection and response.
Is this initiative unique to Cambodia?
No, similar systems exist in Thailand, Vietnam, and other industrializing nations. Cambodia’s approach aligns with regional best practices.
