The golf course at the Fort Dodge Country Club will get some less than pristine water for irrigation under a deal approved by the City Council that will save about 15 million gallons of drinking water that’s now used annually to irrigate the course.

Under the agreement, water used to clean filters at the John W. Pray Water Facility will be piped to the country club for irrigation use.

Every day, the water plant uses about 280,000 gallons to clean various filters. That water, called filter backwash, can’t be used for drinking. Now, it is stored in a lagoon and eventually pumped to the wastewater treatment plant.

As a result of the new agreement, the city will send 160,000 gallons of filter backwash to the country club every day.

The city will build a pump station and pipeline between the water plant and the country club. The estimated cost of that is $171,300.

The city will also loan the country club $165,000 to help it pay for its expenses for the project. That loan will have a 4 percent interest rate.

The country club will construct its own pump station, on-site piping and a storage pond. The estimated cost of all that is $426,000.

The council approved the agreement with no discussion. Councilman Kim Alstott was absent from the otherwise unanimous vote.
