Transcript what happens to water after you use it?

I met in the street a very poor young man who was in love. His hat
was old, his coat worn, his cloak was out at the elbows, the water
passed through his shoes, - and the stars through his soul.

ALL OF THE EASY SOURCES OF WATER ARE
BEING USED.
TO INSURE SUPPLY, WE NEED TO GO TO
MORE EXTREME SOURCES.
POSSIBILITIES FOR INCREASING WATER
SUPPLY INCLUDE DESALINATION AND
TRANSFERRING WATER BY PIPELINE.
THESE ARE ALL EXPENSIVE.
THE BEST OPTION IS USING WATER MORE
EFFICIENTLY.

WHAT HAPPENS TO WATER AFTER YOU USE IT?
WHAT HAPPENS TO WATER AFTER YOU USE IT?
IT GOES INTO THE SEWER, AND, ULTIMATELY,
TO THE WASTE WATER TREATMENT PLANT.
HOW DOES A SEWAGE TREATMENT PLANT
WORK, AND HOW DOES IT DIFFER FROM A
WATER TREATMENT PLANT?
HOW DOES A SEWAGE TREATMENT PLANT
WORK, AND HOW DOES IT DIFFER FROM A
WATER TREATMENT PLANT?
BOTH HAVE TO REMOVE BACTERIA.
A SEWAGE TREATMENT PLANT HAS TO
REMOVE A MUCH HIGHER LEVEL OF SOLIDS,
SO THERE ARE SEVERAL STEPS WHERE
SOLIDS ARE REMOVED AND TREATED.
DRINKING WATER TREATMENT
1.COARSE FILTRATION – REMOVES STICKS, ROCKS,
LEAVES, FISH, BODIES, ETC.
2.COAGULATION – USUALLY THROUGH THE ADDITION OF
ALUM [KAl(SO4)2·12H2O]
3.SEDIMENTATION – ALLOWS THE COAGULATED SOLIDS
TO SETTLE OUT
4.FILTRATION –REMOVES REMAINING BACTERIA AND FINE
SOLIDS
5.DISINFECTION – USUALLY THROUGH CHLORINATION
6.AREATION
7.DISTRIBUTION
DISTRIBUTION
USE/REUSE
WASTEWATER TREATMENT
1. COARSE FILTRATION – BAR SCREEN FILTER
2. GRIT CHAMBER
3. SEDIMENTATION – SEDIMENT GOES TO DIGESTER AND
PART IS CONVERTED TO METHANE GAS. THE
REMAINDER IS USED AS SOIL CONDITIONER
4. AERATION TANK – BACTERIA EAT SOLUBLE ORGANICS
5. CLARIFIER
6. DISINFECTION
7. DISCHARGE
WINSTON-SALEM WASTEWATER TREATMENT PLANTS
PUT WATER BACK INTO THE YADKIN RIVER CLEANER
THAN IT WAS TAKEN OUT FOR USE AS
HOUSEHOLD/INDUSTRIAL WATER.
WATER IS NOT CREATED OR DESTROYED. IT IS SIMPLY
REUSED (RECYCLED).
