Phase one of a project that could replenish the Equus Beds Aquifer is up and pumping.

The Aquifer Storage and Recovery Project, or ASR, was first discussed in the 1990's when the Equus Beds fell to record low levels. Construction on the four-phase project finally began in 2006. Phase one was completed in 2007 to the tune of 27-million dollars. When all four projects are finished, the final bill is expected to run upwards of 225-million dollars.

With just phase one now operating, millions of gallons of water a day can be pulled from the Little Arkansas River during periods of high flows, such as floods. The water is run through a filtration system and thoroughly cleaned, then injected directly into the aquifer or allowed to seep in through recharge basins.

With all pumps operating, 10-million gallons of water can be put back into the Equus Beds in one day. By contrast, a city the size of Salina uses approximately two-million gallons a day.

"All this was new for the state of Kansas," says project engineer Jerry Blain. "We've been able to work with our regulators in Topeka to come up with a set of rules I think provide the protection we need for the aquifer."

Engineers say the Equus Beds could be fully recharged in about 12 years, the first feat of its kind in Kansas, and one that is drawing international attention. Blain has invited engineers from Australia and China to visit and learn more about the efforts underway in Kansas.

Blain says the recharge project is a win-win for all involved. Pipes and pumps will stretch over 150 square miles, taking up only about 400 acres of actual land. There is no requirement that farmers cut down on their irrigation, and in fact the rising water levels mean lower pumping costs.

By comparison, a reservoir would flood thousands of acres and alter or destroy entire ecosystems in its wake.

The Equus Beds is the sole or a primary water source for 35% of the state, including the cities of Hutchinson, Newton, McPherson, and Wichita.

It's expected to take eight years to complete the remaining three phases to the project. When finished, engineers say cities like Wichita will be guaranteed water until the year 2050 and beyond.
