YOU PAY APPROXIMATELY $0.25 PER 100 GALLONS OF WATER USED. THAT’S A REAL BARGIN.

DRINKING WATER STANDARDS EPA SETS DRINKING WATER STANDARDS. EPA REQUIRES COMMUNITY WATER SYSTEMS TO TEST FOR OVER 80 CONTAMINANTS. THE HIGHEST LEVELS ALLOWABLE ARE CALLED MAXIMUM CONTAMINANT LEVELS (MCL’S). FOR CONTAMINANTS THAT COULD CAUSE CANCER, EPA SETS THE STANDARDS SO THAT THERE WOULD BE NO MORE THAT 1 IN 10,000 TO 1 IN 1,000,000 OVER A LIFETIME. FOR NON-CANCER CONTAMINANTS, EPA SETS THE MCL’ S SO THAT THERE WILL BE NO RISK.

DRINKING WATER COMES FROM SURFACE WATER AND GROUND WATER. LARGER CITIES TEND TO USE SURFACE WATER. SURFACE WATER WOULD INCLUDE LAKES AND RIVERS.. Ground water is pumped from wells that are drilled into aquifers. Aquifers are geologic formations that contain water.

We use tap water for various purposes. A typical family of four on a public water supply uses about 350 gallons per day at home (each person about 350 liters per day). A typical family of four that gets water from a private well uses about 200 gallons per day at home. People in the U.S. use a lot more water that people in other countries.

HOW COULD YOU REDUCE THE AMOUNT OF WATER USED AT YOUR HOUSE?

1. TAKE SHORTER SHOWERS. 2. DON’T FILL THE BATH TUB SO FULL. 3. DON’T LEAVE THE WATER RUNNING WHEN YOU BRUSH YOUR TEETH. 4. INSTALL WATER SAVING SHOWER HEADS. 5. DON’T WASH CLOTHES UNLESS YOU HAVE A FULL LOAD. 6. DON’T RUN THE DISHWASHER UNLESS YOU HAVE A FULL LOAD. 7. DON’T LEAVE WATER RUNNING WHEN YOU WASH DISHES BY HAND.

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).
