The Kingman City Council wants more information about a proposal to treat 1.3 million gallons of wastewater per day for use on a golf course at a proposed residential community.
John Lingenfelter and partners would like to use the water on the course for the proposed Villages of Long Mountain community near the Kingman Airport and Industrial Park.
The community would be built on 2,000 acres across Route 66 from the airport near the city's Hilltop Wastewater Facility.
"It has always been a vision of Dr.
John Lingenfelter to reuse the wastewater and save the drinking water for people," said Tom Carter, consultant working with Lingenfelter on the project.
During a Dec.
17 strategic planning retreat for the City Council, City Manager Roger Swenson said continuing to let the treatment plant water evaporate would be less expensive for the city.
"Any reuse of the wastewater would cost the city more money," said Swenson.
"In the long run, would the city be better off to preserve the water for future use?"
Promoters have approached the city at various times to use the water for a power plant, golf courses and agriculture.
City officials considered using the wastewater to irrigate the Cerbat Hills Golf Course but decided it was too expensive.
The city uses 5 percent of water pumped from city wells for the golf course each year.
Wastewater would require treatment before it could be reused for most purposes, including irrigating a golf course.
That would require the construction of a treatment plant and the hiring of personnel working 24 hours per day, seven days per week.
The Hilltop facility was designed as a biological treatment facility with no chemical treatment of the water.
The wastewater goes through a series of wetland ponds where vegetation treats the water naturally.
Evaporation ponds at the end of the facility complete the treatment.
The water that runs out the end of the facility is near potable quality, although not ready for human use, Jeff Corwin, wastewater superintendent, said.
During the summer, when a golf course or agriculture would need the water, almost none would be left, Corwin said.
It all is used by vegetation in the wetlands or evaporates from the evaporation ponds.
"The bottom line is cost," said Public Works Director Jack Kramer.
"Today, it is cheaper to pump good water out of one of our wells."
Retired Kingman City Manager Lou Sorensen explored using the wastewater 10 years ago when the Hilltop facility was constructed.
He estimated the cost of getting the water back to the Cerbat Cliffs Golf Course at $850,000.
Sorensen is a consultant with the Lingenfelter group, which has said using wastewater on a golf course adjacent to the wastewater facility would eliminate the cost of pumping the water several miles into Kingman.
Lingenfelter has drilled a well to city standards on the property to be developed for housing and a golf course.
He wants to work with the city to trade water.
"The well has a definite value to the residents of Kingman," said Mayor Les Byram.
"Using the wastewater would also preserve our aquifer for future years."
Kramer told the council that reused wastewater would definitely cost more per gallon than good water from city or from the Lingenfelter well if only current costs were considered.
"It is a water policy decision the mayor and council will have to make on behalf of the citizens of Kingman," said Swenson.
"They will decide what that water is worth in the future."
