Understanding the irrigation system of a golf course is crucial for maintaining healthy turf grass and providing an excellent playing surface. Water is essential as it makes up 80-85% of a grass plant's weight. This guide covers components including water sources (rainfall, lakes, wells), pump stations, supply lines, and control mechanisms, alongside types of sprinkler heads like rotary and pop-up. It also discusses when to irrigate based on factors like temperature, humidity, and soil moisture for optimal grass health.

Purpose • Keep turf grass healthy • 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
Components • Water Source • Pump Station • Supply Lines • Control Mechanism • Sprinkler Heads
Water Source • Rainfall • Lakes and Ponds • On Site Wells • Municipal Water Systems
Pump Station • Draws Water From Source • Release water into system as needed • Pipes are underground
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
Control Mechanisms Starts and stops the valves Can be automatic or manual Can control one sprinkler or several
Sprinkler Heads • Different Types: • Fixed spray, pop up, bubblers, rotary, and strip • Most Common on Golf Course • Rotary and pop up • Most Turn 360 degrees
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
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
