WELCOME TO THE TANKS
OF LAS VEGAS STREET
other Nature is our instructor
as we clean used water
at the Tanks of Las Vegas Street.
Just as Mother Nature watches over her water day
and night,
the noble Guardians of Wastewater keep
a twenty-four hour a day vigil.
Our task is enormous because each day
we treat approximately 47 million gallons of wastewater
which has been used throughout the realm.
other
Nature scrubs her water as it rushes over rocks in the streams.
Our Wastewater Treatment starts
with the Preliminary Remedy
where sand, grit and larger solids are mechanically separated
from the water.
hen
wastewater flow enters the Primary Sedimentation Tanks
we take advantage of the physical process of gravity
which allows primary solids to settle.
Collection equipment on the bottom of primary tanks
removes this solid matter, called "Primary Sludge".
Floating grease or scum is removed from the top of the tanks.
other
Nature nurses thousands of microbes
who eat harmful bacteria in the water
We created the Secondary Remedy which biologically
removes pollutants.
In this process, also known as activated sludge treatment, microorganisms
use oxygen and gobble up pollutants to stabilize the wastewater.
Our process occurs in an aeration tank or basin.
atching Mother Nature, Clarifiers of the
Secondary Stage
allow microorganisms or activated sludge to settle quietly to
the bottom of the tank.
At this point about 85 to 90 percent of the impurities have been
removed.
hen organic solids have settled to the
bottom of the primary sedimentation
or secondary clarification tanks, this matter is known as sludge.
Mother Nature leaves her sludge at the bottom of streams and rivers,
but we send ours to Clear Spring Ranch
through an 18 mile pipeline.
ome of our water takes a shortcut back
to
nourish Mother Nature's fields and flowers after the
Tertiary Remedy.
This water is called nonpotable
because it is not prepared for the populace to drink.
But it can be reclaimed and reused throughout the kingdom for
landscape irrigation.
ur final measure in treatment is disinfection.
Wastewater discharges from the secondary clarifiers
and enters the Chamber of the Chlorine.
Chlorine is added to kill harmful organisms.
At the end of the chlorine contact chamber,
sulfur dioxide is added to remove the chlorine to prevent
the possibility of chlorine toxicity in Mother Nature's water
ways.
ur
cleaned water then returns to Fountain Creek,
where the water will be used over and over again downstream.
Mother Nature is pleased with the efficiency of our treatment
process.
Mother Nature's process is slow, but we can clean water in a few
hours.
other Nature generally responds slowly
when danger threatens her water.
We, however, have Guardians of Emergency
who protect our environment from enterprises
which might allow destructive or dangerous chemicals to enter
the system.
Our Guardians of Analysis perform
tests
to determine the quality and status of the water.
They are constantly on the look out
for the treacherous environmental contaminants
which might harm our operation.
s
Guardians, we are charged with the mission
of cleaning the used water and returning it to Mother Nature
so creatures large and small can enjoy our water as it flows downstream.
We ask you, our future citizens, to announce
our message of stewardship throughout
the land.
