The Codau presents The Class of Clarinha in the water cycle
fine Cristal, it's time, the clouds are already filled
Yeah! I am so excited to begin the water cycle
will be a long ride, we'll show you everything
we are very important Cristal
so important and so present in people's lives
that often they don't even notice our presence
Our tour begins right here. As you know we exist in three states:
solid, liquid and gas
we go to earth in what state?
liquid, as rain!
hey, so let's go, it's time
uhuuuu
the rain is the result of evaporation of rivers and seas
this evaporation creates clouds
when they are loaded release water as rain
then fall on the earth
and penetrate into the soil
thus making the groundwater
part of us runs across the surface as well?
Yes, they make the springs of water are sources of water, streams, rivers and dams
rivers, for example, flow into the ocean where most of the water evaporates and the water cycle resumes
but that's all?
hmmm, now I will evaporate and become cloud again?
wait Cristal, this whole process is slow
before evaporating again, we'll have a long walk
this is the Uberaba River
from here comes the water that supplies the whole city
Yeah! Where do we go?
for Codau Catchment Water Station
straight to where the tanks are sand and clay that is mixed with water
go here, this pipeline will take us straight to the WTS
WTS? what is this?
is the Water Treatment Station
wow , I'm feeling very clean
here in WTS the water receives many chemicals
as lime and alum
and it is not all, we will still go through those tanks there
and these tanks there are filters to clean the water
the process is very fast, and here we go
spent by coal, sand, fine gravel, coarse gravel
Here they still add fluoride
but for that?
is to help fight tooth decay
and now, let's go where?
for the Codau water tanks
from whence the water is distributed to homes
come on, I want to show how people use water
Mrs. Dulce, brought my friends to visit
hello Clarinha, glad you came
only that way for me to take the Aninha of the bath
it is already there in 15 minutes
I'll fix that now Mrs. Dulce
Wow , creed, what a fright you gave me Clarinha!
this is for you to learn not to waste water Aninha
the fact is you turn off the shower while soaping, so you save water
Ok Mrs. Dulce, I've already taken this tricksy of bath
let's take a walk around the neighborhood to see how it uses water
looks Mrs. Matilde sweeping the sidewalk with the garden hose
does she not know that it wastes a lot of water?
right to use the broom Mrs. Matilde
in addition to not wasting water, is more economical and nature thanks
just look at this pile of garbage in the midle of street
when it rains it clogs storm drains causing floods and diseases
let's get it!
soon after in the house of Mrs. Dulce
Mom's right, a dripping tap wastes lots of water
just look at the tank is full of soap!
really
that's right Cristal, now comes the most interesting
that cool
here is the bathroom right?
well, when people pee and poop the water gets dirty
the water tank full of soap, the water from the toilet
everything goes into the sewer
we follow the path of sewage
come on!
is this all just from the Aninhas’s home?
of course not, here comes also all sewage from the neighborhood
are you seeing this pipe?
I'm!
is the emissary, he collects all sewage and this leads to the STS
STS?
yes! Sewage Treatment Station
let's see what happens
are you seeing?
Here, when the sewage arrives, passes through tanks and several treatment lakes
wow! it stinks
these lakes are full of bacteria that eat this dirty mass
ergh!
That's right, they eat dirt
and are slowly becoming all that goo
in clean water again
wow! is pretty clean again. I'm relieved!
understood, from here the water will be returned to the river, is it?
wow, is too much work, right Clarinha?
all this to preserve water and returns it to the river very, very clean
Here ends our trip
Now we follow the river and start all over again
I can not wait to do it all again
