California’s water solution

  1. 1. California’s Water Solution<br />By <br />Travis Pirtle<br />
  2. 2. California is About to Face a Water Shortage<br />Southern California has relied on the Colorado River for years. <br />The Colorado River has lowered in time. <br />The River also supplies places such as Las Vegas. <br />
  3. 3. How Much Shortage?<br />
  4. 4. About the Shortage<br />The above picture is what Lake Mead, Nevada looked like back in 1999 when the drought started. <br />The bottom picture shows the Hover Dam at the same time during the drought and what is 80 feet below level. <br />Water has risen since then<br />People should not take water usage for granted.<br />Both Photos taken by Jim Wilson of the New York Times. <br />
  5. 5. Solution To Follow<br />Northern California is supplied by two rivers: The Sacramento and the San Joaquin.<br />The Sacramento River helps supply southern California.<br />Possibly fusing together other small lakes and streams? Not enough to supply.<br />Solution 1: limit water usage.<br />Solution 2: desalination.<br />
  6. 6. Water Limit Solution<br />Laundromats decrease hours of operation and days per week.<br />Make use of only public pools, not home. <br />Car wash use of one wash per month per vehicle.<br />Limit outside watering to once per week.<br />Limiting water usage would help preserve what water there is in the Colorado River and possibly give nature time to raise the water level.<br />
  7. 7. Desalination Solution<br />Drinking straight salt water. Highly unlikely.<br />Process is very popular in Saudi Arabia.<br />This would solve water shortage problems.<br />In the U.S., cities would have to meet certain criteria to undergoe desalination.<br />
  8. 8. Desalination Process<br />Uses the ocean for the water supply.<br />Water goes through huge pipelines to filtration.<br />The filtration desalts the water.<br />After desalting, the water goes through purification.<br />Two purification choices: Distillation and Reverse Osmosis<br />
  9. 9. Environmental Issues<br />Such a great solution, what is wrong with it?<br />Pipelines pose danger to marine life.<br />Consumes a great amount of energy to run a desalination plant.<br />Concentrated salt water remains from purification process goes back into the ocean.<br />
  10. 10. Environmental Solutions<br />Use solar power and wind power to help run the desalination plants.<br />Use heavy duty iron grids to be placed on the pipeline intakes to prevent marine life getting sucked in.<br />For the purification process, there is newer technology that is environment friendly and help reduce salt water waste.<br />
  11. 11. Conclusion<br />Water reservation is really important at this time.<br />Setting water limitations for use will most likely give nature a chance to replenish water to the river.<br />Prolonging water usage of primary source will allow technology to improve for desalination in aspect of energy efficiency and environmental safety.<br />California is one of the largest agricultural states.<br />No water means the U.S. economy will be effected as of food shortage.<br />
