6. Introduction to Water Utilities
Water utilities have 3 main jobs:
• Manage water found in
lakes, rivers, and other
places
• Treat (or “clean”) water so
that it is disinfected and
safe to drink and use
• Send clean water to the
public through water pipes
7. Water Utilities & Source Water
Water utilities’ 1st job is to
oversee water in nature (“source
water”). Source water is either:
• surface water (lakes, rivers,
reservoirs), found above the
Earth’s surface
• Groundwater (found below the
Earth’s surface; sometimes
also called an “aquifer”)
Source water is unsafe to drink.
Do you know why?
8. From Source to Utility
How source water
gets to the water
utility
• Pumping
• Gravity
9. Water Utilities & Water Treatment
Water utilities’ 2nd job is to
“treat” source water
• Source water cleaned
and disinfected
• Water becomes safe
• Safe water is called
“Potable”
How can utilities clean and
disinfect source water?
10. Water Utilities & Water Distribution
Water utilities’ 3rd job is
to deliver clean,
disinfected water
• Water moves through
a series of pipes
• Connected pipes =
the “water system
infrastructure”
• Infrastructure handles
40 billion gallons/day
12. How Water Works: from source to you
1a and 1b in this picture
shows water at its
source. In this case the
sources include a
reservoir and a river
2 shows the water
treatment plant where
the source water is
cleaned and disinfected
The red arrow shows
water moving from its
source to the treatment
plant for cleaning and
disinfection
13. How Water Works: from source to you
Item 3 shows you an
elevated tank.
The elevated tank stores
clean, disinfected drinking
water that comes from
the treatment plant shown
in 2
In 4, you see large pipes
called distribution mains.
Distribution mains carry
water from the treatment
plant or storage tank to
service lines. They also
provide water to hydrants
for fire protection.
14. How Water Works: from source to you
In the previous slide, we
talked about pipes
called distribution
mains. Item 4 illustrates
a distribution main.
Distribution mains
connect to service lines
as shown in item 5.
Service lines carry
clean, disinfected water
to the plumbing in a
building.
Once the water is in a
building’s plumbing
system, you just turn on
the faucet to drink it!
16. Do You Know…????
How long can humans live without
water?
How much of the human body is
made of water?
We can live 30+ days without food,
but only 4-7 days without water
The human body is about 60% water
17. Do You Know…????
We must drink at least 6-8 glasses
of water each day
How much water should humans
drink each day?
How much of the Earth’s surface is
made of water?
About 70% of the Earth’s surface is
water
How much of the water on Earth is
suitable for drinking?
1% of the water on Earth is OK to
drink. The other 99% is unsuitable to
drink because it is salt water, or
frozen in glaciers and Polar ice caps
18. The Value of Drinking Water
In the U.S., drinking water from your
faucet costs….
….less than about one cent per
gallon
Bottled water costs…
….about $1.20 per gallon
Lemonade costs…
….about $3.40 per gallon
Soda costs…
….about $3.79 per gallon
19. Tap vs. Bottled Water: Yearly Value
Drinking 5 gallons of
water a week for a
year:
• Tap water: $2.60 per
year
• Bottled water:
$312.00 per year
Yearly savings drinking
tap water vs. bottled
water?
• $312.00 - $2.60 =
$309.40
• Think about it: a family
of 4 saves over
$1,000/year drinking
tap water instead of
bottled water
20. How Long Will Our Water Last?
• Supplies limited
• Many countries lack
clean fresh water that
is disinfected and safe
• Droughts, changing
weather patterns limit
supply
• Pollution: natural or
human causes
21. Conservation: Preventing Pollution
• Don’t flush products
or pills down toilet
• Don’t pour paint or
used oil down drain
• Take toxic products to
hazardous waste
facility
• Always clean up your
pet’s waste
22. Conservation: Saving Water
How can you save water?
• Reduce, reuse, recycle
• Water Wisely
• Shorter showers, fewer
baths
• Fix running / leaking toilets
• Don't leave faucet running
23. Conservation: for Life
• One person makes a
difference
• You are not alone –
others will join/follow
• Everyone has a stake
• We must conserve
for future generations
