Water Use and Conservation Practices on U.S. Golf Courses
Just recently a comprehensive study on golf course water use and conservation was published (1). The Environmental Institute for Golf sent a survey to superintendents at 16,797 golf facilities in the United States. Of these surveys, 15 percent were returned. The entire report can be found at: http://www.eifg.org/programs/EIFG_GCEP_Vol_2.pdf
Although done in the United States some of the interesting points include:
• Golf courses comprise an estimated 484,978 ha of irrigated turfgrass in the United States, and their total annual water use averaged over 3 years (2003-2005) is estimated at 2,852,675 megalitres
• Twelve percent of the golf courses use re-use water (effluent, reclaimed)
• In the eastern United States 57 to 64 percent of the golf courses do not pay for irrigation water. In the southwestern United States, only 18 percent of the golf courses do not pay for irrigation water.
• Golf courses that used various types of water conservation methods:
• Wetting agents (92%)
• Hand watering (78%)
• Keeping the turf drier (69%)
• Mulch landscape beds (51%)
• Utilize irrigation scheduling techniques (weather stations, forecasts, etc.) (47%)
