REVERSE OSMOSIS Meeting: 11 – 13 - 12
The Ogallala Aquifer • Located beneath the Great Plains • Covers 174,000 square miles • Wichita uses the portion called the Equus Bed. • 27% of irrigated land is on top of this aquifer • 30% of all United States water for irrigation comes from this • Provides drinking water to 82% of people within the boundaries
The water is divided like so • Irrigation – 50% • Cities – 24% • Industrial Use – 13% • (Spirit falls in this category) • Recreational/Other – 3% • (We aren’t really sure what goes in this category.) • Swimming pools maybe? • 10% is pulled away by the river systems
The Aquifer Storage and Recovery Project • A complicated system to help replenish the aquifer • $550 million dollar cost • The year it was finished, Wichita had an above-average amount of rain and the system wasn’t used properly • Wichita was paying for nothing, basically. • Phase I is the only phase completed so far.
Kansas vs. Colorado • Going on since 1902 • Fighting over rights to the water in the Arkansas river • It’s illegal in Colorado to own a rain barrel. This water is supposed to go to the river. • Last issue was in 2009
Purposes of the Exhibit • Demonstrate that we are using more water than can be naturally replenished to the aquifer. • We want to show how to use less water from the environment • The aquifer • Rain water • Cheney Reservior
Cont’d. • Show how re-using grey water (un-potable) will benefit the economy and city • Focus on water re-use • Show possible solutions to slowing or stopping aquifer depletion • For example, using not drinkable water for industrial use instead of drinking water.
Cont’d Again • We need to convince the city of Wichita that this is a good thing • As opposed to the city making less money because less water is being purchased. • We need to be sure to not make the city of Wichita look like bad guys. • Stephen thinks we should not change the original RO project too much, just give it a “facelift”.
