  5. Lesson One:Water Consumption - The Water You Drink

  6. Do You Know…???? How long can humans live without water? We can live 30+ days without food, but only 4-7 days without water The human body is about 60% water We must drink at least 6-8 glasses of water each day How much of the human body is made of water? How much water should humans drink each day?

  7. How Much Water Should Kids Drink? Factors affecting how much water kids should drink: Age Height & weight Activity level Climate type

  8. How Can We Get the Water We Need? Cucumber Tomato Apple Banana One slice of cheese pizza Chicken nuggets One slice of bread French fries Buttered popcorn Potato chips Cucumber - 97% water Tomato - 95% water Apple - 80% water Banana - 75% water Slice of cheese pizza - 47% water Chicken nuggets - 47% water One slice of bread - 37% water French fries - 35% water Buttered popcorn - 5% water Potato chips - 1% water

  9. How Many 8 ounce Cups of Water are in Your Body? What is 60% of that? How much do you weigh in pounds? There are approximately 8 pounds in a gallon; divide #2 answer by 8 The answer to #4 tells you how many 8 ounce cups of water are in your body I weigh “X” pounds “X” pounds x 60% = ? pounds of water ? pounds ÷ 8 = ?? gallons of water ?? gallons x 16 cups = ??? cups of water in your body Multiply #3 answer by 16 (there are 16 cups in a gallon) How many 8 ounce cups of water are in YOUR body?

  10. The Value of Drinking Water In the U.S., drinking water from your faucet costs…. ….less than about one cent per gallon Bottled water costs… ….about $1.20 per gallon Lemonade costs… ….about $3.40 per gallon Soda costs… ….about $3.79 per gallon

  11. Cost of Drinking Water from a Faucet vs. Bottled Water 12,000%

  12. Yearly Cost of Drinking Tap Water Multiply .01 cent per gallon x 5 gallons per week = Cost of tap water = .01 cent per gallon $2.60 per year .05 cents per week There are 52 weeks in a year Multiply .05 cents per week from above x 52 weeks in a year =

  13. Yearly Cost of Drinking Bottled Water Multiply $1.20 per gallon x 5 gallons per week = Cost of bottled water = $1.20 per gallon $312.00 per year $6.00 per week There are 52 weeks in a year Multiply $6.00 per week from above x 52 weeks in a year =

  14. Tap vs. Bottled Water: Yearly Value Drinking 5 gallons of water a week for a year: Tap water: $2.60 per year Bottled water: $312.00 per year What do you save per year if you drink tap water instead of bottled water? $309.40 What else could you buy with your savings instead of bottled water?

  15. $309.40 Extra Dollars a Year??? What would you do with $309.40 extra dollars a year? • Treat your little brother to a movie once a month for a year • Order one medium pizza & breadsticks every month for a year • Buy some new school clothes for $309.40 • Buy two tickets to a professional NBA game in your home town • Put it in the bank and add it to your college savings account • What else????

  16. Lesson Two:Water Systems - How You Get Your Water

  17. Introduction to Water Utilities Water utilities have 3 main jobs: Oversee water found in lakes, rivers, and other places Treat (or “clean”) water so that it is safe to drink and use Send clean water to the public through water pipes

  18. Water Utilities & Source Water Water utilities’ 1st job is to oversee water in nature Water in nature is called Source Water. Source Water is either: surface water (lakes, rivers, reservoirs), found above the Earth’s surface Groundwater (found below the Earth’s surface; sometimes also called an “aquifer”) Source water is unsafe to drink. Do you know why?

  19. From Source to Utility How source water gets to the water utility Pumping Gravity

  20. Water Utilities & Water Treatment Water utilities’ 2nd job is to “treat” source water Source water cleaned Water becomes safe Safe water is called “Potable” How can utilities clean source water?

  21. Water Utilities & Water Distribution Water utilities’ 3rd job is to send you clean water Water moves through a series of pipes Connected pipes = the “water system infrastructure” Infrastructure handles 40 billion gallons/day

  22. How Water Works: from source to you

  23. How Water Works: from source to you 1a and 1b in this picture shows water at its source. In this case the sources include a reservoir and a river 2 shows the water treatment plant where the source water is cleaned The red arrow shows water moving from its source to the treatment plant for cleaning

  24. How Water Works: from source to you Item 3 shows you an elevated tank. This is also known as a “water tower” The water tower stores clean drinking water that comes from the treatment plant shown in 2 In 4, you see large pipes called distribution mains. Distribution mains carry water from the treatment plant or storage tank to service lines. They also provide water to hydrants for fire protection.

  25. How Water Works: from source to you In the previous slide, we talked about pipes called distribution mains. Item 4 illustrates a distribution main. Distribution mains connect to service lines as shown in item 5. Service lines carry clean water to the plumbing in a building. Once the water is in a building’s plumbing system, you just turn on the faucet to drink it!

  26. Lesson Three:Water Conservation - Becoming a Friend to Water

  27. Fun Facts About Water The Earth’s surface is 70% water but only 1% of this water is suitable for drinking Each American uses from 80-100 gallons of water a day… that’s more than the weight of some elephants! 6 gallons of water is used in the growing and production of…?? French fries

  28. How Much Water Do Americans Use? On average, how much water in gallons (daily per person) does each American use? Estimates range from 80 -100 gallons daily per person

  29. Our Water World The Earth’s surface is about 70% water… Only about 1% of this water is suitable for drinking 70% water 1% suitable for drinking

  30. Water Numbers So far, you have learned that: The Earth’s surface is about 70% water Only 1% of that 70% is suitable for drinking We use about 80-100 gallons of water per day per person We use over 300 gallons of water per day at home The United States uses 355 billion gallons/water a day

  31. How Long Will Our Water Last? Our water supplies are limited (many countries do not have enough clean fresh water) Droughts & changing weather patterns affect our water supply Water can become polluted through natural or human causes

  32. Saving Water in Your Home Be a friend of water at home: Take shorter showers or fewer baths Ask parents to water the lawn less often Check the toilets to make sure they’re not running or leaking Don't leave the faucet running

  33. Saving Water in the Neighborhood Be a friend of water in your neighborhood: Don’t use weed killer on your lawn Pull weeds (don’t spray with chemicals) Pick up trash you see Clean up after your dog (animal waste gets into our water supply)

  34. Saving Water for Life One person can make a difference You are not alone – others will join/follow Everyone has a stake in the future of our world’s water supply You can create a better world for future generations

  35. Summary • Water is necessary for all living things to survive • Public water utilities protect public health by “treating” source water • We protect water sources by not polluting • We save water supplies by not wasting it
