Transcript of Providing Access to Clean Water

Providing Access to Clean Water Overview Summary of Issue

Significance of Issue

Role of Engineers

Connection to Engineering Disciplines

Recent Developments

Future Developments Why is This Issue Important? 1 in 6 people does not
have access to clean water 3.4 million Number of people who die
from lack of access to water 2.5 billion Number of people who lack
access to modern sanitation More people own a
cellphone than a toilet 1.5 million Number of deaths from
diarrhea per year Why Should Engineers
Focus On This Issue? 2.53% of water on Earth is fresh water
THE REAL ISSUE IS ACCESS Engineers can develop
cost-effective technologies
chemical processes
new structures Desalination of seawater is expensive Why is This Issue
Difficult to Solve? Recent Developments Predictions for
Future Developments Recycling Wastewater Thank You! Any Questions? Connection to Engineering Disciplines Allison Keeton, Lynn Recker, Lindsey Werner Works Cited Reducing Water Use Distillation Units Conclusion Summary Quick Statistics: Mechanical Engineering: Biomedical Engineering: Access to clean water is crucial

Current purification - expensive

Need better processes and technology

Recent developments

Future developments Shallow Wells Dug by small rigs to around 150-200 ft. Recent Developments PUR Packets Powdered mixture
Technology similar to water systems in developing countries
Turns contaminated water to drinkable water How It Works: Coagulation
Disinfection Expenses

Political Conflicts

Natural Pollutants 70% of Earth is covered with water
Over 97% is salt water
2% of fresh water is frozen in glaciers

Water is not distributed evenly across the world

Drinking unclean water causes serious diseases
E. Coli, Cholera, Hepatitis A
