There are many variables that impact the life
of an irrigation system. Exposure to freeze/thaw cycles, the type of soil
surrounding the pipe, quality of the water and the intensity of use of the
system are just a few factors that must be considered. Another consideration is
the advancements in irrigation technology. While the pipe may still be good,
the control system may need to be updated to capitalize on improvements in
water and energy management that can save thousands of dollars per year, or
even per month, depending on the cost of water and power in your area. The only
sure way to determine if the irrigation system on your course is due
replacement is to employ an irrigation engineer to perform a system analysis.
As a very general recommendation, it is time to start investigating the need
for replacing the entire irrigation system once it has reached 15 years of age.
The control system should be evaluated at least every 10 years to determine if
advances in technology justify an upgrade.

The USGA and Chevron have committed to using the game of golf to encourage students in science, technology, engineering and math (STEM) disciplines.
This commitment has led to the creation of extensive golf-focused STEM teaching tools, and has resulted in charitable contributions to support golf-related
programs through Eagles for Education
At U.S. Open Championships the Chevron STEM ZONE™ is an interactive experience highlighting the science and math behind the game of golf through a variety of hands-on exhibits and experiments.
The partnership has also produced educational materials such as the Science of Golf video series and a nationally-distributed newspaper insert which are provided to teachers as tools to enhance existing curriculum in schools. These lessons teach the science behind the USGA’s equipment testing, handicapping, and agronomy efforts.
For more interactive experiences featuring golf-focused STEM lessons, visit the partnership homepage.
