California’s Water Solution

By Travis Pirtle

Page 2: California’s water solution

California is About to Face a Water ShortageSouthern California has relied on the

Colorado River for years. The Colorado River has lowered in time. The River also supplies places such as Las

Vegas.

How Much Shortage?

Page 4: California’s water solution

About the ShortageThe above picture is what Lake Mead,

Nevada looked like back in 1999 when the drought started.

The bottom picture shows the Hover Dam at the same time during the drought and what is 80 feet below level.

Water has risen since thenPeople should not take water usage for

granted.

Solution To FollowNorthern California is supplied by two rivers:

The Sacramento and the San Joaquin.The Sacramento River helps supply southern

California.Possibly fusing together other small lakes

and streams? Not enough to supply.Solution 1: limit water usage.Solution 2: desalination.

Water Limit SolutionLaundromats decrease hours of operation and

days per week.Make use of only public pools, not home. Car wash use of one wash per month per vehicle.Limit outside watering to once per week.

Limiting water usage would help preserve what water there is in the Colorado River and possibly give nature time to raise the water level.

Desalination SolutionDrinking straight salt water. Highly unlikely.Process is very popular in Saudi Arabia.This would solve water shortage problems.In the U.S., cities would have to meet certain

criteria to undergoe desalination.

Page 8: California’s water solution

Desalination ProcessUses the ocean for the water supply.Water goes through huge pipelines to

filtration.The filtration desalts the water.After desalting, the water goes through

purification.Two purification choices: Distillation and

Reverse Osmosis

Environmental IssuesSuch a great solution, what is wrong with it?Pipelines pose danger to marine life.Consumes a great amount of energy to run a

desalination plant.Concentrated salt water remains from

purification process goes back into the ocean.

Page 10: California’s water solution

Environmental SolutionsUse solar power and wind power to help run

the desalination plants.Use heavy duty iron grids to be placed on the

pipeline intakes to prevent marine life getting sucked in.

For the purification process, there is newer technology that is environment friendly and help reduce salt water waste.

ConclusionWater reservation is really important at this time.Setting water limitations for use will most likely

give nature a chance to replenish water to the river.Prolonging water usage of primary source will

allow technology to improve for desalination in aspect of energy efficiency and environmental safety.

California is one of the largest agricultural states.No water means the U.S. economy will be effected

as of food shortage.
