Water is vital for life but scarce in many parts of the world. Pollution from construction waste, litter, and untreated wastewater is contaminating lakes and rivers in Vietnam. While water treatment plants can help mitigate pollution, currently only 25% of industrial parks treat their wastewater before discharging it into rivers. Individual actions like using water filters and conserving water can also help address water issues.

3. Water Facts

4. Water is vital
You can last weeks without food, but only days
without water!
Man lost in Sahara desert for 10 days Nepal earthquake victim survived after 80 hours

5. Water scarcity
Drought Flood
Out of 7.2 billion people in the world
748 million do not have access to an
improved source of drinking water

6. Ocean pollution

7. Polluted lakes in Hanoi
• Dumping construction waste at lakes
• Littering (domestic wastes)
• Directly discharging municipal
wastewater
Eutrophication at Truc Bach lake
Linh Dam lake
Hao Nam lake Ho Me lake (Truong Chinh str)

8. Contaminated rivers in Vietnam
Illegal pipe of discharging wastewater
at Long Thanh Industrial park
• Total about 232 industrial parks (143 has
Wastewater treatment plant)
• Total wastewater capacity ~ 1 million cubic
meter/day
• 75% without treatment and discharge to
the river
Fish died

9. Freshwater is little but..
Does meat make the planet thirsty?

10. How to mitigate pollution?
Aquatic rafts on To Lich riverCleaning the river bed
Exercising machine purifies Ngoc Khanh and Thanh Nhan lake

11. Wastewater treatment plants
Yen So WWTP 200,000 cubic meter/day
• Pilots (in small scale): Kim Lien, Truc
Bach, Bay Mau, North Thang Long
• High investment WWTP: Yen So,
Yen Xa (To Lich river) by 2020
• Call for construction: West of Nhue
river and Phu Do
Truc Bach WWTP 2,300 cubic meter/day

12. Advanced water treatment
Reverse Osmosis Membrane Desalination
• 9,500 desalination plants worldwide
• total capacity of 8.5 billion gal. per day (32 billion liters)
• creating a total market worth $95 billion
Nano filtration membrane
Forward Osmosis

13. Access to clean drinking water
Lifestraw water filter RO filter for household
Faucet water filter
Over 80,000 X-Packs are
fielded to US military
personnel

14. What can you do in the future?
To be a politician
To be an environmental engineer
