MCDI Technology-Based Local Demonstration Project Briefing Session in Vietnam
Vietnam is a country rich in water resources, but?
🌊 Abundant water resources vs. poor access
Total annual renewable freshwater resources per capita 9,350㎥ (world average 6,000㎥)
(Source: FAO Aquastat)
However, access to safe drinking water remains a challenge:
- 7 million+ children: Lack of access to clean water at school (UNICEF 2025)
- Rural 50% and above: Use of contaminated water (MONRE 2024)
- Groundwater 80%+: E. coli contamination (mountainous/rural areas)
☠️ Serious pollution situation
Arsenic (As) contamination: Mekong/Red River Delta average 159μg/L
(WHO standard 10μg/L) 16 times↑)
Annual Tens of thousands of casesCauses outbreak of waterborne diseases
(Vietnam Ministry of Health, MOH 2024)
Water demand is expected to surge to 321 tpa3t by 2030.

Vietnam's Water Crisis
The dire reality revealed by official data
Water Scarcity: By the Numbers
⚠️ water-scarce countries
Vietnam's annual water availability per capita is 3,840㎥, falls below the IWRA water shortage standard (4,000㎥).
"This means it is classified as a "Water Stressed Country”.
Water resources status
- ▪ Total water resources: approx. per year 844km³
- ▪ Domestic sources: 40% (340km³)
- ▪ Foreign inflow: 60% (504km³)
- ▪ Current demand: 11.7 billion ㎥/year (increasing trend)
Regional water resource imbalance
Severe Water Pollution
🏭 Industrial wastewater problem
Among the industrial complexes About 70% Inadequate or non-operational wastewater treatment facilities
Widespread unauthorized discharge of hazardous substances exceeding standards (heavy metals, CN⁻, H₂S, etc.)
Most of the rivers in major cities do not meet the standards for domestic water supply (Class B and below)
🏘️ Domestic sewage problems
City sewage treatment rate: 12.5% (2024)
Mostly domestic sewage Unprocessed River/lake discharge
Government Target: Urban Wastewater Treatment Rate by 2030 50% attainment
⚕️ Health crisis
Diseases caused by the use of contaminated water account for a large proportion of all diseases. About 70-80% Charge estimate.
Annual About 9,000 people died 및 100,000+ people develop cancer Relevance raised.
