Victor Hugo Victor Hugo 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. HOW WATER IS USED IN THE U.S. (2000 DATA) North Carolina Water Concerns 1.Drought 2.Stormwater Runoff 3.Agricultural Pollution 4.Aquifer Depletion PIG FARM LAGOON CENTRAL COASTAL PLAIN USE AREA Concern about aquifer depletion and salt water intrusion. Water Used in the Homeater/water-footprint-calculator/ 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? 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(SO 4 ) 2 12H 2 O]KAlSO 4H 2 O 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). GO TO THIS SITE AT YOUR CONVENIENCE AND SEVERAL OF THESE TO READ. SEE WHAT IS HAPPENING IN THE WORLD CONCERNING WATER PROBLEMS.
