A typical golf course requires 100,000 to 1,000,000 gallons (378.5 m3 to 3,785 m3) of water per week in summer to maintain healthy vegetation. Improving the water efficiency usually requires proper scheduling of the irrigation and improving irrigation uniformity.ll these issues can lead to excessive water use, especially where the golf course is located in regions with arid climates. Turf requires an average of 25 to 60 inches (63.5 cm to 152.4 cm) of water annually, depending on climate, to maintain a healthy appearance.
