BACKGROUND
The first phase of the Flint Hills Athletic Park was completed in 2013. The park includes three fully
irrigated athletic fields. Currendy, the fields are irrigated using City water supplied by a connecrion to the
water main along Akron Avenue. Based on water use totals from 2013, 2014, and 2015, the average water
usage for the fields is 3.5 million gallons (I�ZG) per year.
A similar project has recently been completed that utilizes an irrigation well for irrigating athleric fields. In
2012, the Ui�lore Ball Fields Irrigation Well was completed and is used for irrigating two softball fields. As
a reference, the average water use is on average 1.6 �TG per year,which is less than half of the Flint Hills
Athletic Park. The construcrion cost for the irrigation well was �116,000.
The costs associated with constructing an irrigation�vell and connecting the existing irrigarion system to
run off the irrigarion well are anticipated to be $195,000. The design and cost of the well takes into
account any future phases of the park that will be serviced by the well for irrigation purposes.
Based on the water usage of 3.5 MG per year, at the current irrigation wateY rate of$2.60 per 1,000 gallons,
the yearly cost of water is $9,200. The cost of electricity and maintenance per year is estimated at$700 per
yeaY for the irrigation well option. The yearly savings from the water less the electricity and maintenance is
$8,500. A simple life cycle cost analysis was done to evaluate the benefit over the life of the project. With
the initial improvement costs and the annual savings, the break-even point is after the 22nd year of
operation. The basis for this analysis is based on the current phasing and use of the Flint Hills Athletic
Park. There are future phases planned that could potentially add an additional4 athletic fields and green
space to the park. If these phases are initiated in the future, the anticipated yearly water use for the entire
site and savings could potentially increase by 50% and the break-even point could be significandy reduced.
Based on the benefit and long term break-even point of the project, staff does not recommend pursuing
the construction of an irrigation well to serve the Flint Hills Athletic Park.
SUMMARY
Staff�vould like to uutiate a discussion regarding the Flint Hill rlthletic Park irrigation well.
