  1. A World of WaterPart 2 Today’s Goal: • To learn where your drinking water comes from and the steps that are taken to make sure your tap water is clean and safe. • To explore some history of water in Kentucky and McCreary County.

  2. A World of WaterPart 2 • Water played a critical role in defining early settlements.

  3. A World of WaterPart 2 • Most major cities were first settled due to their location near a water supply

  4. A World of WaterPart 2 • What are the two main rivers that run through McCreary County? • The Big South Fork River • The Cumberland River

  5. A World of WaterPart 2 Follow the Flow

  6. A World of WaterPart 2 • McCreary County Water District was started in 1962 with 75 customers. 1962

  7. A World of WaterPart 2 • Today, McCreary County Water District has over 6,000 customers.

  8. A World of WaterPart 2 • The Water District also provides water for the Federal Prison in Pine Knot, Cumberland Falls State Park, and even another county (Whitley County).

  9. A World of WaterPart 2 • McCreary County now has over 2,000 fire hydrants. Over 2,000

  10. A World of WaterPart 2 • McCreary County Water District uses surface water from two sources. • The Big South Fork River • The Laurel Creek Reservoir

  11. 6.5 MILLION A World of WaterPart 2 • The two water treatment plants that are operated by McCreary County Water District can treat up to 6,500,000 gallons of water a day.

  12. Let’s go through the treatment process together A World of WaterPart 2

  13. A World of WaterPart 2 Water can be withdrawn from The Big South Fork River or the Laurel Creek Reservoir at three different levels. Intake MCWD’s Raw Water Intake – located near Big Creek on the BSF River

  14. A World of WaterPart 2 Electric pumps move the water into the flash mix while chemicals are added to it. Flash Mix

  15. A World of WaterPart 2 The chemicals make tiny pieces of dirt and debris stick together. When the particles get big enough, they sink to the bottom. Coagulation Before After

  16. A World of WaterPart 2 The water moves through a settling chamber and through settling tubes where it slows down, allowing the sediment to fall out Sedimentation

  17. A World of WaterPart 2 Water then moves into the final clarifying chamber where it is given additional time to allow any remaining particles to settle out. Polishing Basin When it comes to water treatment, TIME is your friend!

  18. A World of WaterPart 2 Water passes through filters made of coal, sand, and gravel. Filtration Gravel Sand Coal

  19. A World of WaterPart 2 Chlorine is added to disinfect the water. Disinfection Kills Germs!
