How has environmental engineering affected you today?



Reducing, Reusing, Recycling to
eliminate excess waste of resources
Disposing of waste (sewage,
garbage...)
What about the space we use, the
CO2 we emit...

Clean (and convenient!) drinking water

Clean air

Clean wastewater

Clean soil
Global and Local implications
Let me tell you about the world I’d like to see
 First, I would like to see the water, ground, and air not
polluted. As in, not having chemicals dumped in somehow.
Like, for the air, no burning plastic or Styrofoam. For the
water, no trash or oil being dumped in. For the ground, no
littering, and for the air, no smog or smoke.
 Second, no endangered species, no animal over population,
when trees are cut another is planted in its place, and I
would also like no more rainforest cutting.
 Third, for people, I would like to see more kindness,
cooperation, and more respect for the world we share.
 That is the world I would like to see.

Environmental Engineering Tasks
between 2010 and 2050
Safe drinking water for everyone
Wastewater treated before discharge to the
environment everywhere
Public policy: politicians or advisors to
politicians
Maintaining and upgrading the
infrastructure
Environmental Engineering Tasks
between 2010 and 2050
Water shortages – reduce, reuse, recycle
Pharmaceuticals in wastewater
Contaminated site remediation
Waste minimization
Environmental Ethics/Justice
Water Treatment Design
 Water supply
 Where does the water come from?
 How much water is needed?
 How does it get to the cities?
 Is the water safe to drink?
 How is the water purified?
 NYC
 Small Communities in Honduras

New York City Water
Where does New York City’s water come
from?
 How does the water get to all the buildings?
Where does the water go when it “goes
down the drain”

Could NYC get its water from
the rainfall on the City?
Solution
Drinking Water Treatment for NYC?
 Sierra Club: “City would spend 1.5 billion [to
build a filtration plant] instead of protecting
Croton watershed”
 NYC Department of Environmental Protection:
“Of the 7,400 surface drinking water supplies in
the U.S. at least 7,310 have filtration plants
designed to insure that the water these systems
provide to their consumers is safe.”
 ENGRI 113: What do you think?
Water Treatment Plant Project
Goal: Design, build, operate, and automate
a miniature drinking water treatment plant.
Here's your chance to develop your
engineering skills!
Logistics
Form teams
Max of 4 teams per section
