1. Golf Course Irrigation

2. Purpose Keep turf grass healthy Produces a good playing surface
water comprises 80 to 85 percent of the weight of a grass plant
Produces a good playing surface
Way to apply pesticides and other chemicals

4. Components Water Source Pump Station Supply Lines Control Mechanism
Sprinkler Heads

5. Water Source Rainfall Lakes and Ponds On Site Wells
Municipal Water Systems
Rain fall is the preferred source. This is because it is free, clean, and distributed uniformly. Unfortunately we cannot schedule when it will rain.
Lakes and ponds are used to irrigate and are also used as design features in golf courses.
Well depths to ground
water can be as shallow as 20 to
50 feet or as deep as 1,500 to 2,500
feet (Beard, 2002).
Muncipal water is easy to access however in time of a drought it can become restricted and this is also expensive.

6. Pump Station Draws Water From Source
Release water into system as needed
Pipes are
underground

7. Supply Lines
Large Pipes at the pump station and become smaller towards the sprinkler
Check Pressure Rating
Materials of Pipe:
PVC
Galvanized iron
Poly ethylene
Pressure rating – estimated max pressure of water a pipe can handle before failing

8. Control Mechanisms Starts and stops the valves
Can be automatic or manual
Can control one sprinkler or several

9. Sprinkler Heads Different Types: Most Common on Golf Course
Fixed spray, pop up, bubblers, rotary, and strip
Most Common on Golf Course
Rotary and pop up
Most Turn 360 degrees

10. Subsurface Irrigation Drip
Irrigation hoses are located under the surface of the grass throughout the golf course
Sensors implanted in the ground for more accurate watering
sensors are implanted in the ground that let the groundskeepers know if there are any areas that need extra attention

11. When to Irrigate Most irrigate by the calendar
Best way to irrigate is by assessing frequently
Temperature, humidity
Soil moisture
Wind conditions
Cloud cover
Predicted rainfall
